PSYC 354 Part III:
The following data are based on numbers taken from the Bureau of Labor Statistics surveys
from the years 2009–2013, with some modifications. They represent the average weekly pay
for wage and salary earners measured at 4 different quarters each year and broken down by
gender. Enter these data into a new file containing one variable for gender and one variable for
salary. For the gender variable in column 1, code women as 1 and men as 2
o Remember to define these in Value Labels as covered in presentations since
o There will be twenty “1”s and twenty “2”s (as many participants as in each
group). The corresponding earnings will be entered in the salary column (second column). If you need an example, look at the set-up of gender in the “Lesson 21 Practice Data
File 1” document.
Men 1) 749

928 933 946 937 951 968 931 981 954 In SPSS, compute descriptive statistics for each gender for these data.
The necessary steps are covered in the last 3 slides of this module’s SPSS tutorial. Answer- SPSS Table- Descriptive Statistics for Weekly Pay by Gender:
(Paste one table; should include weekly pay grouped by men and women)
Create a boxplot describing the average overall weekly salary for each gender.
Answer- SPSS boxplot: 2) 3) Based on these data, what is the mean weekly income for men? Answer 4) What is the standard deviation of the weekly income for women? Answer Page 1 of 3 PSYC 354 Part IV: Cumulative
Questions 1-4 1) The BDI (Beck et al., 1961) is an instrument
widely used to assess levels of depression in
individuals in a variety of settings. The scores range from 0–63 (whole numbers
only). A researcher administers the BDI to a sample
of college students. The results appear in the
table below. They are entered as two columns to save
space (i.e., you will not need two columns in
the SPSS file, only one). BDI Scores
11 Using SPSS, run a frequencies analysis on these scores that includes: A Frequency Table Table of Descriptive Statistics
o Include measures of central tendency, variability/spread, and
distribution shape. Paste the output into your homework file. Answer- SPSS Table- Frequency Table for BDI Scores:
Answer- SPSS Table- Descriptive Statistics for BDI Scores (Include measures of central
tendency, variability/spread, and distribution shape):
Create a graph to describe the data set.
Justify why this graph is the best choice for these data.
Answer- SPSS graph 2) Explanation/ Justification
Based on your SPSS output, what is the numerical skewness value of this data
What does this value say about how the scores are distributed?
Answer 3) Page 2 of 3 PSYC 354 Explanation 4) Based on your graph and your answers above, which measure of central
tendency is most appropriate for describing this group of scores?
