Mary, the counselor, wants to test whether there is any meaningful difference in depression scores among women and men clients of hers. She has 13 women clients and 14 men clients. The mean depression score of men clients is 4.5, while that of women is 5.3. The pooled standard error is 0.5 of the two groups. Is there any gender difference in depression levels among her women and men clients?

  1. Indicate the null and research hypothesis.
  2. What test do you do to test the null hypothesis above, among independent-sample t-test, paired-sample t-test, or one-sample t-test?
  3. What is the t-statistics?
  4. What is the d.f. for the test?
  5. Do you reject the null hypothesis? - Use the t-table on p. 163
  6. So, is there a statistically significant difference between women and men clients of Mary for their depression scores?

A group of researchers wants to examine whether taking multiple practice quizzes improve scores on tests. They compare the exam scores for a sample of n1 = 12 students who took multiple practice quizzes with the test scores of a sample of n2 = 10 students who did not do any practice quizzes. Results of the study revealed that the practice quiz group had M1 = 95, SS1 = 52. The no quiz group had M2 = 92, SS2 =...

Researchers studied nausea among a sample of hospitalized patients. They used a t-test to compare average nausea scores in men and women. They report men had an average score of 1.02 and woman had an average score of 1.79. (p<0.001) Which statement is correct? Men had significantly less nausea Men had 79% less nausea but we can not determine if this is a significant relationship. A paired t-test was appropriate because the patients were all from the same hospital. There...

Below are depression scores for women who report experiencing intimate partner violence. These scores were taken from a random sample of 10 women. In the general population, depression scores are normally distributed with a mean (μ) of 31 and a standard deviation (σ) of 2. You hypothesize that this sample is not representative of the general population. Specifically, you hypothesize that these women form a distinct sub-population, with specifically HIGHER depression, relative to the general population. That is, if they...

Researchers wants to know if taking the herbal supplement St. John's Wort will affect depression. First, they measure the depression level of a sample of n = 4 depressed people (Pre-Test Scores). Then after a week of taking St. John's Wort, they again measure the sample's depression levels (Post-Test Scores). Note that high scores on the depression measure indicate more depression, whereas low scores indicate less depression. Participant Pre-Test Scores Post-Test Scores A 9 6 B 12 5 C 13...

A group of researchers want to determine if there are any significant differences in marital satisfaction between male and female spouses. To test this hypothesis, they collected data on marital satisfaction from 28 couples (i.e., 28 men and 28 women). They observed that the average marital satisfaction among men was 6.5, and the average among women was 6.0. The sum of squares for the difference scores (SSD) was 440. Additionally, male and female spouse marital satisfaction were strongly related (r...
