Partner #2: Romisa Shakeriniasar

INSTRUCTIONS

1.Each partner download and open the dataset in SPSS.

2.Complete this worksheet with your partner.

3.Download the worksheet as a PDF.

4.Turn in just one worksheet per group on Moodle, due Friday 4/1 by 11:59 pm.

5.I DO NOT anticipate this taking more than a normal class period (i.e., 1 hour 40 minutes), IF that long. If, for whatever reason, this lab is taking your group considerably longer than that, PLEASE reach out to me on Slack before proceeding.

PART 1: Do some stuff in SPSS!

***EDITORS? NOTE: The questions listed in the table below come directly from the GSS dataset; I did NOT write them. This dataset is from 2012, but some of the language used in it feels slightly aged (e.g., ?Homosexual couples??).***

Step 1: Choosing Variables

Select 6 variables from this list and summarize them in Table 1 below. THREE variables must be ORDINAL with 4 levels/groups; THREE must be interval.

Table 1: Variables

Variable

(Level) SPSS Variable Name Explain what the variable measures IN YOUR OWN WORDS

1 (Ord) Attend How often do you attend religious services?

2 (Ord) income The group that the family?s total income (before taxes) fall into for the previous year

3 (Ord) educ The highest educational level achieved

4 (Int) www hours The time spent online

5 (Int) hrs1 Hours spent doing work the previous week

6 (Int) sexfreq Estimated amount of sex in the past 12months

Step 2: Graphs!

Next, create a graphical representation of each variable! Copy and paste the graphs into the spaces below.

INSTRUCTIONS:

1.Click Analyze

a.Descriptive Statistics ? Frequencies

2.Frequencies window appears

3.Find the first of your 6 variables

a.Select it and move it into the right-hand window

4.Click Charts

a.Select HISTOGRAM

b.Click SHOW NORMAL CURVE ON HISTOGRAM

5.Click CONTINUE, THEN OK; SPSS will create the graph on the same output as your FDs

6.Copy and paste graph below

7.Repeat for other 5 variables

Figure 1: [Attend]

Figure 2: [income ]

Figure 3: [educ]

Figure 4: [www hours]

Figure 5: [hrs1]

Figure 6: [sexfreq]

Step 3: Measures of Central Tendency and Dispersion

Now that we have these descriptions of our variables, let?s first examine what the typical case in each looks like (MCT) and then how much variability is in each (dispersion!).

INSTRUCTIONS:

1.Click Analyze

a.Descriptive Statistics ? Frequencies

2.Frequencies window appears

3.Find the first of your 6 variables

a.Select it and move it into the right-hand window

b.Find the other 5 variables and do the same thing

4.Click Statistics

a.Check boxes for mean and standard deviation

5.Click OK and SPSS will create the frequency distributions on an output just like before

a.BUT you will also see the statistics you asked for in a summary table at the top

6.Use this info to complete Tables 2 and 3 below

a.HINT: To find the Category Label for ordinal variables?

i.At the bottom of SPSS, select VARIABLE VIEW

ii.Find your variable?s ROW in the column on the left, scan across to the VALUES column

iii.Click on the cell in Values column, then click the small button that appears with three dots

iv.A new box will pop open called Value Labels; in here, you will see the categories associated with each value of your variable!

Table 2: Measures of Central Tendency and Measures of Dispersion ? Ordinal variables

SPSS Name Level of Measurement Mean (Number) Category (Label) Range SD

Attend Ordinal 2.71 8 2.592

income Ordinal 14.84 24 6.476

educ Ordinal 13.41 14 2.41

Table 3: Measures of Central Tendency and Measures of Dispersion ? Interval variables

SPSS Name Level of Measurement Mean Range SD

www hours Interval 14.52 184 19.555

hrs1 Interval 35.79 88 14.25

sexfreq Interval 4 6 1.509

Step 4: Calculating Z-Scores

You now have lots of information about this sample on the variables you chose ? plenty of ways to describe people?s answers. Let?s add another descriptive statistic to that list: z-scores! Using the steps below, you can easily calculate z-scores for EACH participant on your chosen variables; remember, these will pinpoint how far from the mean each score is.

INSTRUCTIONS:

1.Click Analyze

a.Descriptive Statistics ? Descriptives

2.Descriptives window appears

3.Find your three INTERVAL variables

a.Move them to the box on the right

4.Check the box that says ?Save standardized values as variables?

5.Click OK

a.That will create three NEW variables in your dataset labeled ?zVARIABLENAME? (e.g., ?zclass?)

6.Click on DATA VIEW at the bottom of the SPSS dataset screen

7.Find the COLUMN for your first variable

a.Right click on the column header and select SORT DESCENDING

i.Enter the top value into Table 4 below for ?Highest z-score?

ii.Repeat for other two variables

b.Right click on the column header again, but this time select SORT ASCENDING

i.Enter the top value into Table 4 below for ?Lowest z-score?

ii.Repeat for other two variables

8.Use the textbook Appendix B (Normal Curve Table) to complete Table 4

Table 4: Z-scores ? Interval Variables

SPSS Name Level of Measurement Highest z-score % of scores above % of scores below Lowest z-score % of scores above % of scores below

www hours Interval 8.67 0% 100% -0.74 77% 23%

hrs1 Interval 3.73 0% 100% -2.44 99% 1%

sexfreq Interval 1.32 10% 90% -2.65 99% 1%

Step 5: Reporting and Interpreting Results

You now have quite a bit of info about the sample in this dataset. Using the information from Tables 2-4, write a sentence to summarize the distribution of each variable.

1.For the ordinal variables, include the mean, range, and SD in your sentence. Be sure to place the variable IN CONTEXT ? that is, mention what it?s measuring.

2.For the interval variables, include all of the above, but also add in the z-score info from Table 4. Mention, for instance, the percentage of cases that fall above or below a certain value in the dataset (e.g., ?Roughly 98% of all people would be expected to be younger than age 89, which had a z-score = 2.75?).
