Question

Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Also, remember that we divide the p value in half when reporting one-tailed tests with 1 – 2 groups.

A researcher wants to investigate whether mindfulness training improves ability for employees to notice positive experiences in the workplace, and if this differs by gender and/or disposition. Employees were randomly assigned to one of two groups: no training or a half-day session. Gender was categorized as male or female. Disposition was categorized as follows: optimist, pessimist or realist. Ability to notice positive experiences in the workplace was quantified using a Likert-based ambulatory assessment. A factorial design was used to analyze the data.
1. How many factors are there?		Answer:
2. What is the factorial notation for this design?		Answer:
3. If there is a main effect of Disposition, would Tukey’s HSD need to be calculated? Why or why not?		Answer:
4. What is the dependent variable?		Answer:
5. How many conditions (cells) are there in the scenario?		Answer:
6. How many null hypotheses (and thus, F-ratios) are there in this scenario?		Answer:

Use one of the following key terms to answer each of the following questions. KEY TERM BANK (separated by commas): Univariate, Multivariate, meta-analysis, F-ratio, interaction, main effect
7. Use this type of statistics to analyze data when you have more than one dependent variable.	Answer:
8. This describes the effect of a single variable as if there were no other variables in the study.	Answer:
