Question

Using the class data set "sociability2016.sav" (see the note below), answer the following questions: a. Using the "compute" command in SPSS, generate a new composite variable (soc) by summing up the individual items socl, soc2 to soc9. This new variable therefore, measures individual's overall sociability level (the higher the score, the more sociable the person is). Using SPSS again, calculate the mean, median, standard deviation and variance of this new variable (i) for the entire sample, (ii) for females only, and (iii) for males only. b. For those whose total score is below 20 (i.e. soc 20), how many of them are males and what is the percentage of it? c. What is the T score equivalent for soc 20? d. It is known that Edward's sociability score is 20. Determine Edward's percentile rank based on (i) normal approximation, (ii) the empirical distribution of the data. Note: The file "sociability2016.sav" is a SPSS data file. Some of the variables include: Label Variable Individual item score of the Sociability Scale socl-soc9 sal sa6 Individual item score of the Social Anxiety Scale (notice that the 4th variable, sa4r, is a reverse item and it has been properly recoded) 1 male, 2 female Sex

Explanation / Answer

Please note that all these are calculated in SPSS:

a)

(i)soc=SUM(soc1,soc2,soc3,soc4,soc5,soc6,soc7,soc8,soc9)

for male:

mean=22.78

median = 20

variance =437.85

standard deviation = 20.92

for female:

mean=23.16

median = 21

variance =212.64

standard deviation = 14.58

b. 70 males are there whose value is less than 20 out 174 total people whose value is less than 20 which is ~40.22%

c.Z score is 0.12

T score = 51.2
