SPSS Assignment

 Instructions:

 

 1.  Variables highlighted in red (see file SPSS Data Set.274) must be entered in the data editor as numeric values. Refer to the Doctoral Application Coding Guide (page 4).

 

2.  Print a copy of the data editor file with all relevant variables included.

3.  All required printouts must be attached to the assignment.

4.  Answer to all questions must be typed. 

Note:

 1.  Assignment must be typed. Only typed assignments will be graded.

 

2.  Printouts and Datasheets must be uploaded with the assignment. No credit will be given if the original printouts and datasheet are not uploaded with the assignment.

 

3.  No duplication of answers or printouts in anyway. 

Last Name Ending: A-I are assigned variables   Ethnicity   GPA      (Refer to page 1)

                                J-R are assigned variables   Category   Pretest   (Refer to page 2)

                              S-Z are assigned variables   SES           GREQ   (Refer to page 3)

 

I.     Identify the characteristics (scale of measurement; qualitative or quantitative; continuous or

       discontinuous) of scores for the following variables:

       Gender    SES    GREQ 

II.   Use SPSS to run the following:

        1.  a frequency distribution for the variable SES and the variable GREQ

 

        2.  the appropriate graph, either a histogram with a normal curve or bar graph, for the variable SES and for the variable GREQ

 

        3.  analyses on GREQ scores: mean, median, mode, standard deviation, skew, and the Pretest score for the top 10% of the distribution.

 

        4.  compare the mean analysis command, calculate the mean and standard deviation for SES based on GREQ scores

 

 III.   Use the printouts from the analyses to answer the following:

 

          1.  Use the analyses from GREQ scores to interpret the mean, median, mode, standard deviation, skew, and the top 10% of the distribution.

 

          2.  Use the analyses from the compare the mean printout to answer the following:

        a.  Which SES performed better on the GREQ subscale?

 

        b.  Which SES demonstrated more consistent scores on the GREQ subscale?
