Module 3

Assignment 1: Discussion: Generating Research Questions for z-Tests and t-Tests

By Saturday, August 1, 2015, post your response to the prompt in the Discussion Area below. Present the rationale for your selection. Be very specific in your presentation. Through Wednesday, August 5, 2015, review and comment on at least two peers’ responses, wherein you present your feedback regarding the research questions proposed.

Discussion

Suggest one psychological research question that could be answered by each of the following types of statistical tests:

  • z test
  • t test for independent samples, and
  • t test for dependent samples

 

Assignment 2: LASA 1 Quiz

You are allowed to use your textbook so that you can access the equations needed to solve the problems. The test is not timed, but you should complete the test in one sitting. Make sure you review the readings and module notes for Modules 1 throughbefore you begin.

Complete the quiz by Wednesday, August 5, 2015.

Module 4

Assignment 1: Generating hypotheses for t-tests and ANOVAs

By Saturday, August 8, 2015 post your response to the prompt in the Discussion Area below. Through Wednesday, August 12, 2015 review and comment on at least two peers’ responses, and offer your thoughts on their hypotheses and any recommendations you have to enhance their contributions.

Assignment 1: Discussion

Post a null hypothesis that would use a t test statistical analysis.. Use the same hypothetical situation taken in the t test hypothesis, and turn it into a null hypothesis using a one-way ANOVA analysis and a two-way ANOVA. 

 

Assignment 2: Analyzing with ANOVA

Submit your answers to the following questions using the ANOVA source table below. The table depicts a two-way ANOVA in which gender has two groups (male and female), marital status has three groups (married, single never married, divorced), and the means refer to happiness scores (n = 100):

  1. What are the independent variables and their levels? What is the dependent variable?
  2. State all null hypotheses associated with independent variables and their interaction? Also suggest alternate hypotheses?
  3. What are the degrees of freedom for 1) gender, 2) marital status, 3) interaction between gender and marital status, and 4) error or within variance?
  4. Calculate the mean square for 1) gender, 2) marital status, 3) interaction between gender and marital status, and 4) error or within variance.
  5. Calculate the F ratio for 1) gender, 2) marital status, and 3) interaction between gender and marital status.
  6. Identify the critical Fs at alpha = .05 for 1) gender, 2) marital status, and 3) interaction between gender and marital status.
  7. If alpha is set at .05, what conclusions can you make?

Please Note: The table that you see in the assignment has been slightly modified from the one presented in the module notes since it is beyond the scope of this unit to have students calculate p values. Instead you are asked to calculate the F value and compare it to the critical F value to determine whether the test is significant or not.

By Wednesday, August 12, 2015, deliver your assignment to the M4: Assignment 2 Dropbox.
