Problem
1. Provide a null hypothesis for two of the hypotheses presented in the Heide & Sellers, 2014 article.
2. Explain the use of a t-test. Provide a research question that could be answered with a t-test.
The T-Test tests the difference between two groups on a continuous dependent variable.
3. What level of measurement is needed for the independent variable and dependent variable for the following tests?
a. ANOVA
b. Correlation
c. T-test
d. Chi square
4. Using the Practice Data Set Spring 2018 Recoded, answer the following questions (use either Excel or SPSS) - provide the test statistic (chi square, t value, r value, etc.) and significance:
a. Is there a significant relationship between gender of respondents and choice of instructor?
b. Is there a significant difference between genders on reported number of hours studied each week?
c. Is there a significant difference between people who are currently employed on the number of courses they are taking this semester?
d. Is there a significant relationship between CJ experience and support for the death penalty?
5. SPSS provides a significance statistic. How do we use this to tell if there is a significant relationship between variables (describe interpretation)?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
