Study Notes
Choosing the Right Statistical Test
- To compare the scores of husbands and wives in a survey on marital happiness, use a paired t-test (since the data is paired and related).
- To determine if there is a significant difference in reaction times between two groups exposed to different stimuli, use an independent samples t-test (since the data is from two independent groups).
- To compare the heights of a sample of 30 men to the national average height for men, use a one-sample t-test (since the data is compared to a known population mean).
- To compare the blood pressure of the same individuals before and after an intervention, use a paired t-test (since the data is paired and related).
- To compare the means of two independent groups with different sample sizes, use an independent samples t-test (since the data is from two independent groups with different sample sizes).
