T-test

Order Description

one analysis (i.e., Part A or B) will use a dependent (or paired) samples t-test and the other (i.e., Part A or B) will use independent samples t-test. Figure out which test is appropriate, and then proceed with your analysis

Results of both X2 and X1
Part A
Thirty teachers at ACE Charter School were given a 20% raise in their salary in August of 2015. How was their job satisfaction (“0” = very unsatisfied to “50” = very satisfied) affected as a result? Use job_satisfaction(1).sav data. (Note: You can make causal inferences in this analysis.)
What is the research question?
What is the null hypothesis?
What is the research hypothesis? (Directional)
Basic descriptive analysis of the variables used (e.g., mean, median, mode, range, skewness, etc.)

Part B
Compare the highest years of education between men and women using practice(1).sav data. (Note: Avoid causal inferences here, and just talk about the differences between men and women in the analysis.)
What is the research question?
What is the null hypothesis?
What is the research hypothesis? (Non-Directional)
Basic descriptive analysis of the variables used (e.g., mean, median, mode, range, skewness, etc.)
Write out the results in an APA format.
Please include appropriate tables from the SPSS output used in your analyses.

An Example of a Paired-Samples t-Test Result
“Using a sample of 99 participants, a paired-sample t-test was conducted to compare the number of words recalled (from 0 to 15) in ginkgo and placebo conditions. There was a significant difference in the number of words recalled for ginkgo (M=6.23, SD=3.91) and placebo (M=4.35, SD=3.45) conditions; t (99)= -4.12, p < 0.001. These results suggest that consumption of ginkgo is related to a significant or meaningful increase in one’s memory. The size of the effect is moderate at .51.”
An Example of an Independent Samples t-Test

“Using a sample of 200 participants, an independent samples t-test was conducted to compare the number of words recalled (from 0 to 15) in ginkgo (n=100) and placebo (n=100) conditions. There was a significant difference in the number of words recalled for ginkgo (M=5.95, SD=3.91) and placebo (M=5.25, SD=3.60) conditions; t (198)=1.99, p = 0.03. These results suggest that ginkgo group had greater word recall than their placebo counterparts. The size of the effect is small at .24.”
