Assignment 2

Please try to work on the following questions individually. If you have difficulties, you can work with other students. However, you are required to turn in the assignment individually.

1. Fifteen men and fifteen women in an introductory psychological statistics course have taken their midterm exams. Their scores are listed here. (For gender, 1=male and 2=female) Create an SPSS data file using the data below. Name the variables “gender” and “score”. Make sure to add the value labels for “gender.”

Hint: Since there are two variables, you are only creating two columns. You can add the column for “student”, if you like.

Student	Gender	Score	Student	Gender	Score
1	1	87	16	2	89
2	1	53	17	2	73
3	1	92	18	2	91
4	1	70	19	2	76
5	1	78	20	2	75
6	1	73	21	2	89
7	1	91	22	2	81
8	1	60	23	2	83
9	1	77	24	2	68
10	1	82	25	2	86
11	1	85	26	2	55
12	1	33	27	2	89
13	1	88	28	2	89
14	1	98	29	2	70
15	1	88	30	2	93

2. Run a frequency table on the variable, gender. Copy and paste the output into a Word file and describe the table briefly. Your output table should look like the table below.

Table1: Gender

		Frequency	Percent	Valid Percent	Cumulative Percent
Valid	male	15	50.0	50.0	50.0
	female	15	50.0	50.0	100.0
	Total	30	100.0	100.0

3. Repeat the above for the variable, score.

4. Open the GSS93subset data in SPSS and answer the following questions. (You can find the dataset when you open SPSS. 1. Open SPSS. 2. File. 3. Open data 4. GSS93subset)

a. What is the percentage of people who favor the death penalty?

b. What is the valid percentage of people who favor the death penalty?
