1.When conducting an independent t-test, what is the dependent variable?

a.The experimental conditions

b.The scores

c.One of the independent variables becomes the dependent variable in the analysis.

d.The term 'dependent variable' does not apply to the t-test.

2.The null hypothesis in a two-tailed, independent t-test of means would be:

a.m1 m2

b.m1 m2

c.m1 = m2

d.m1 m2

3.Choose the correct statement:

a.if the null hypothesis is true, there is no difference between population means.

b.if the null hypothesis is false, the samples are considered the same.

c.if the null hypothesis is true, there is a difference between population means.

d.m1 will never be equal to m2

4.An inferential statistical test yields a p-value of .015. Which of the following is true?

a.This finding is statistically significant at the .01 level of significance.

b.This finding is statistically significant at the .05 level of significance.

c.This finding is statistically significant at the .001 level of significance.

d.This finding is not statistically significant.

A researcher is interested to see if there is an average difference in the age of male v. female CJ381 students. To examine this, she conducts a t-test. The SPSS output is shown below:

5.Construct a one-tailed research hypothesis based on the research question above. (1 pt)

6.Write up the results of the t-test in full APA format. Remember, this means that you should include the following:

-mean and standard deviation for each group

-the t statistic

-the df

-the observed p-value (remember, this is a one-tailed hypothesis test)

-indicate what the significance test tell you. (4 pts total)

A researcher is interested to see if a mentoring program impacts student retention. He compares retention rates for students who were and were not mentored. To examine this, he conducts a Chi Square test. The SPSS output is shown below:

7.What is the research hypothesis (note how the problem is worded to indicate if it is one or two tailed)? (1 pt)

8.Write up the results of the Chi Square results in full APA format. Remember, this means that you should include the following:

-the chi square statistic

-the df

-the observed p-value

Be sure to indicate what the significance test tells you. (2 pts total)
