SOC 390 SPSS Assignment The Independent Samples t-Test

Question 1

1 / 1 pts

You recently learned about the joy of hypothesis testing, and now you are eager to put it to use!!! You wonder if men and women differ in their perception of how well they understand political issues facing our country. Gender is recorded in the “gender” variable in the data, with 1 = female and 0 = male. Political understanding is recorded as “polunderstand” in the data and measured using the following question and response options:

• I feel that I have a pretty good understanding of the important political issues facing our country.

1 = strongly disagree

2 = disagree

3 = neither agree nor disiagree

4 = agree

5 = strongly agree

Based on your research question (do men and women differ in perceived political understanding), you will most likely conduct a:

Negative one-tailed test

Two-tailed test

Positive one-tailed test

Question 2

1 / 1 pts

You now turn to SPSS to conduct an independent samples t-test. You find that the t value (with equal variances assumed) is (enter your answer to rounded to 3 decimal places, i.e., 10.001, not 10.01, not 10.1, not 10). The significance for this t value is (enter answer to 3 decimal places). Do NOT enter any + or - signs in your answers above.

Answer 1:

2.519

Answer 2:

0.013

Question 3
