What are the characteristics, uses, advantages, and disadvantages of each of the measures of location and measures of dispersion? Discuss them with examples

Measures of location and measures of dispersion are two different ways of describing quantitative variables. Measures of location are often known as averages. Measures of dispersion are often known as a variation or spread. Both measures are helpful with describing statistical information. (Lind, Marchal, & Wathen, 2015)
The different measures of location include: the arithmetic mean, the median, the mode, the weighted mean, and the geometric mean. All of these measures of location pinpoint the center of a distribution of data. An advantage of measures of location is that the averages show us the central value of the data. A disadvantage of only using measures of location is that we may not draw an accurate conclusion because an average does not tell the spread of the data. Some examples of using measures of location include: finding the average price of a concert ticket, finding the average age of homeowners in a community, finding the averages shoe size of boys between the ages of 13-19, and finding the average amount of money people spend on food annually. (Lind, Marchal, & Wathen, 2015)
The different measures of dispersion include: the range, the variance, and the standard deviation. All of these measures of dispersion tell us about the spread of the data and it helps us compare the spread in two or more distributions. Advantages of using measures of dispersion are that it gives us a better idea of the range in which an average was calculated, and it is easy to calculate and understand. A disadvantage of using measures of dispersion is that it is a broad measurement because it only shows the maximum and minimum values of data. For example, the salaries of dentists in the state of Georgia might range from $70,000-$120,000 (just a made up example – not necessarily accurate data). This information is great for someone to know the range of dentist salaries, but it lacks in showing specific information about dentists’ salaries. (Lind, Marchal, & Wathen, 2015)

What are the characteristics, uses, advantages, and disadvantages of each of the measures of location and measures of dispersion? Discuss them with examples.
These are the measures in common use of location and dispersion: arithmetic mean, median, mode, weighted mean, and geometric mean. The arithmetic mean, median, and mode The mean usually refers to the arithmetic mean or average. This is just the sum of the measurements divided by the number of measurements. We make a notational distinction between the mean of a population and the mean of a sample. The general rule is that Greek letters are used for population characteristics and Latin letters are used for sample characteristics. Therefore: “A% * B%” denotes the arithmetic mean of a population of observations and “A * B” denotes the mean of a sample of size selected from a population. The mean can be thought of as a center of gravity of the data values. This property of the mean has advantages and disadvantages. The mean is a natural measure of location for data that have a well-defined middle of high concentration with the frequency decreasing more or less evenly as we move away from the middle in either direction. The mean is not as useful when the data is heavily skewed.
The median is estimated by first ordering the data from smallest to largest, and then counting upwards for half the observations. The estimate of the median is either the observation at the centre of the ordering in the case of an odd number of observations, or the simple average of the middle two observations if the total number of observations is even. The median has the advantage that it is not affected by outliers, so for example the median in the example would be unaffected by replacing ‘2.1’ with ’21’. However, it is not statistically efficient, as it does not make use of all the individual data values.
“The “mode” is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.” It is not used much in statistical analysis, since its value depends on the accuracy with which the data are measured; although it may be useful for categorical data to describe the most frequent category. In the set of numbers:13, 18, 13, 14, 13, 16, 14, 21, 13. The mode is the number that is repeated more often than any other, so 13 is the mode.
The geometric mean is a type of mean or average, which indicates the central tendency or typical value of a set of numbers by using the product of their values. A geometric mean is often used when comparing different items finding a single “figure of merit” for these items when each item has multiple properties that have different numeric ranges.
The variance, range, and standard deviation are the measures of dispersion. In statistics, dispersion is the extent to which a distribution is stretched or squeezed. A measure of statistical dispersion is a non-negative real number that is zero if all the data are the same and increases as the data become more diverse. Most measures of dispersion have the same units as the quantity being measured. In other words, if the measurements are in meters or seconds, so is the measure of dispersion.

I. Physical Network Design
Introduction

Consider introducing the overall objective of the network design. Look into UMUC’s Strategic Plan, how would the network design help the stakeholders, the leadership
of the university, the students, and the instructors achieve their goals? How would a great network design contribute to students (your) experiences in learning? To
do this we look at five aspects of a network design herein to support the leadership to help meet the goals of the strategic plan.
A. Network Topology

Business Needs

In this section, you will assess the business needs of the company. Use the information provided in the scenario to analyze the need for infrastructure or equipment.
If you need more information, feel free to ask your instructor or make some assumptions. If you make some assumptions, be sure to list them. This section is not about
the actual infrastructure or equipment, but it should discuss the business needs of the company.

Example

ABS Enterprises believes that employees’ health, well­being, and morale have a significant impact on the productivity of the employees and thus the overall results or
output of the company. The company wants to invest in a facility that will provide the most return on investment while still providing a facility that employees will
use. The company has 20 employees and wants needs one or more servers and two printers. All computers should be able to communicate, but the HR staff of 5 needs to be
on a separate network due to the sensitive information on their PC’s.

Proposed Topology

Select one or more topologies to use for this design (star, bus, mesh, ring- Please note that the star topology is the most commonly used). This section should be used
to provide details of the selected infrastructure or equipment. Include the model, manufacturer, features, and cost. Below is an example topology. Topologies can be
created using Microsoft Visio, or you can create a free account at gliffy.com and create diagrams.

Justification

(Each section should contain the reasoning you present to justify the selection you made for your proposal. Look at it as your platform to tell finance and operations
personnel why this should be selected for the network design)
B. Network Media

Note: (Choose wired or wireless)Be aware that your solution needs to include support for the selected media. For example, if you choose wireless, ensure you have
wireless adapters for your desktops.

Business Needs

Assess the business needs.

Proposed Network Media (include network wiring diagrams)

Select one or more network media to use for this design.

Justification

Justify your determination that the selected media will meet the business needs.

C. Network Devices

Business Needs

Assess the business needs.

Proposed Network Devices

Select network devices to use to implement and support your design. Include setup and location information for the devices. Provide a comprehensive list of devices,
including the quantity of each device needed.

Justification

Justify your determination that the selected network devices will meet the business needs.

Example: I selected a Cisco 2621 Router in order to connect the HR users to the rest of the company’s employees

D. Network Security Devices

Business Needs

Assess the business needs.

Proposed Network Security Devices

Select network security devices to use to secure the network. Include setup and location information for the devices. Provide a comprehensive list of devices,
including the quantity of each device needed.

Justification

Justify your determination that the selected network security devices will meet the business needs.

Example: I selected a Cisco ASA 5510 Firewall in order to protect the company’s network.

E. Computer Systems

Business Needs

Assess the business needs.

Proposed Computer Systems

Select computer systems (servers) to use to implement the network design. Include setup and location information for the devices. Provide a comprehensive list of
devices, including the quantity of each system needed.

Justification

Justify your determination that the selected systems will meet the business needs.

Example: I selected Windows 10 Professional for the operating system, because it is the newest, most secure, and stable version of Windows for end users.

II. Network Addresses Design (in its entirety)

A. Subnetting

Subnetting is a process of breaking a large network into small networks known as subnets. Subnetting happens when we extend the default boundary of the subnet mask.
Basically we borrow host bits to create networks (i.e., subnets).

We have been assigned the network address 199.1.2.0. Based on the chart below, we know this is a Class C address. This is determined by observing the first octet of
the IP address, which is 199. This octet falls in between 192 and 223.

Class Octet Decimal Range
A 1 – 126
B 128 – 191
C 192 – 223

Each class has a predefined default subnet mask that tells us the octets, which are already part of the network portion, as well as how many bits we have available to
work with.

Class Subnet Mask Format
A 255.0.0.0 Network.Host.Host.Host
B 255.255.0.0 Network.Network.Host.Host
C 255.255.255.0 Network.Network.Network.Host

CIDR (Classless Inter Domain Routing)

CIDR is a slash notation of the subnet mask. CIDR tells us the number of on bits in a network address.

● Class A has default subnet mask 255.0.0.0. that means first octet of the subnet mask has all on bits. In slash notation it would be written as /8, means
address has 8 bits on.

● Class B has default subnet mask 255.255.0.0. that means first two octets of the subnet mask have all on bits. In slash notation it would be written as /16,
means address has 16 bits on.

● Class C has default subnet mask 255.255.255.0. that means first three octets of the subnet mask have all on bits. In slash notation it would be written as /24,
means address has 24 bits on.

Scenario

The building will house four computer labs that will be used for instruction. In the building diagrams above, the labs are labeled Classroom #2 and Classroom #4 on the
first floor and Classroom #1 and Classroom #5 on the second floor; each computer lab will have a closet. Each lab will have 25 computers: 23 student computers, 1
instructor computer, and 1 server in the closet for instructional use.
In addition, there will be a Student Computer Lab that will provide computer access to students to do their homework. There will be 25 computers in this lab and a
server in the closet. To allow students access to library resources, the library will also have 20 computers for the general public to use and 5 computers for library
staff.
There needs to be separation between students, staff, and public access networks. The open Wi-Fi also needs to be separate from the other three groupings.
Finally, there are various offices in the building. Each of these offices will have one computer for staff use, with the exception of the admissions office, which will
have five computers. There will be two server rooms, one on the first floor and one on the second floor.

 

Methodology

Given the aforementioned scenario, we are going to use the 192.168.0.0/24 network and create a total of 8 subnets, with 25 hosts on each subnet. The chart below
describes structures the scenario to include each subnet and required hosts.

Subnet Description Required Hosts
Students in Classroom 1 Computer Lab 23Computers
Students in Classroom 2 Computer Lab 23Computers
Students in Classroom 3 Computer Lab 23Computers
Students in Classroom 4 Computer Lab 23Computers
Students in Student Computer Lab 24Computers
Public Access network 20 Computers

This week, you learned about active reading and analysis by looking more closely at a passage from a selected reading. In doing so, you uncovered ideas in the “Turning Off, Dining In” article that may have been difficult to identify during your cursory, literal reading of the text.

In this journal, reflect on the importance of active reading and analysis by further revisiting the article you selected for Writing Notes. Please note that you will not be doing a deep dive analysis yet—that will come next week. For now, simply consider the importance of analysis and how it will help you write your final essay.

To prepare for this assignment, please re-read your selected article and your notes from Module 1. Then, either using the MindEdge Notebook or a Word Document, answer the following questions:

Who do you think your audience will be in your critical analysis essay? Describe this audience, and explain how they would benefit from any insights produced from your analysis of your selected article.

Why is analysis so important for your selected reading? How will it help your audience understand the author’s goal in a clearer, more captivating way?

After re-reading your article and notes from Module 1, what do you believe is your goal in analyzing your selected article? Will you provide additional context to help your audience understand the importance of the author’s goal, or will you use your essay as an opportunity to persuade your audience that the author’s goal is incorrect?

In total, the reflection should be three fully developed paragraphs (5-8 sentences each) in length (consider one paragraph per question). As you work on the journal,

NOTE: PLEASE BE CLEAR AND CONCRETE ON IDENTIFYING THE AUDIENCE

PROMPT: Please be detailed and concrete about the audience.

Thanks

Please use APA style double spacing with 12 font Also I will send two files labeled Mother Tongue guidelines for writing.

Smartphones for online study

Smartphones for online study
The attached document are the first and second chapters of my dissertation (Intro and Lit Review). It includes comments and needed changes from my dissertation advisers. Please make their recommended changes with academic professionalism. Below is a summation of their comments. Chapter 1. What we miss in this chapter is your own motivation for doing this study. We’d expect to know where you are coming from, why you care, maybe why your institution cares about the research. It would help, I think, to provide the justification for the study which is still a bit vague. You certainly establish that smartphone use has increased but we’re less convinced that you’ve established cause for concern about approaches to study or engagement. We think the problem is that you’re inclined to make the assumption that there is a causal direction of influence from smartphone use to approaches/engagement. There doesn’t seem to be any evidence to base that on. It’s easier to justify a general exploration of the possible correlations between them, either way. So the questions need to be phrased carefully to reflect this. Chapter 2. Fine on technology etc but still a little weaker on learning stuff, meaning the chapter is rather unbalanced. Pretty uncritical presentation of approaches to learning and engagement as concepts (both these sections slide quickly into more discussion of smartphones). Transactional distance theory surely needs to come after the critical discussion of these concepts, not dropped in at random as it seems to be at the moment. I also think the chapter needs to end with a return to the research questions, showing what light the literature has shed on them (otherwise why do the review?).
