Question: A researcher is studying the effectiveness of two different teaching methods, A and B, on student performance in mathematics. The researcher randomly assigns 100 students to either method A or method B. After a semester, the researcher gathers data on each student's math test scores. The mean test score for students in group A is 85 with a standard deviation of 5, while the mean test score for students in group B is 88 with a standard deviation of 4. Determine if there is a statistically significant difference in the mean test scores between the two groups at a significance level of 0.05.
Answer:
To address this question effectively, our expert employs rigorous statistical methods:
Define the Hypotheses:
- Null Hypothesis (H0): There is no significant difference in the mean test scores between teaching methods A and B.
- Alternative Hypothesis (H1): There is a significant difference in the mean test scores between teaching methods A and B.
Select the Test:
- We use a statistical method that helps compare the effectiveness of teaching methods A and B.
Analyze the Data:
- The mean test score for group A was 85 with a standard deviation of 5, while group B scored 88 with a standard deviation of 4.
Interpret the Results:
- After comparing the test scores of the two groups, we found that there was a statistically significant difference in the mean test scores between teaching methods A and B.
