DV=Final exam scores (continuous)
Best method of analysis= independent sample t-test

Are the student final exam scores in classroom A significantly different than the average of classroom B, 80%? Provide the Independent Variable, Dependent Variable, and best method of analysis.

To determine if the student final exam scores in classroom A are significantly different from the average of classroom B (which is 80%), we need to identify the Independent Variable (IV), Dependent Variable (DV), and the best method of analysis.

IV: The independent variable in this case is the student final exam scores in classroom A. This is the variable that you will manipulate or compare to see if it has any effect on the dependent variable.

DV: The dependent variable is the average score of classroom B (80%). This is the variable that you are trying to measure or observe to see if it is influenced by the independent variable.

Method of Analysis: To compare the student final exam scores in classroom A with the average of classroom B, you can use a statistical test called the independent samples t-test. This test compares the means of two independent groups to determine if there is a significant difference between them.

Here's how you can conduct the independent samples t-test:

1. Collect the final exam scores of the students in classroom A and calculate their mean.
2. Calculate the standard deviation of the scores in classroom A.
3. Obtain the average score of classroom B (80%) and subtract it from the mean score of classroom A.
4. Divide the result by the standard deviation of the scores in classroom A.
5. Finally, use a t-distribution table or statistical software to find the p-value associated with the calculated t-value.
6. Compare the p-value to a predetermined significance level (e.g., 0.05) to determine if the difference between the classroom A scores and the average of classroom B is statistically significant.

If the p-value is less than the significance level, it indicates that the difference between the two groups is statistically significant, suggesting that the student final exam scores in classroom A are significantly different from the average of classroom B.

We do not do your homework for you. Although it might take more effort to do the work on your own, you will profit more from your effort. We will be happy to evaluate your work though.

You assuming that we know what IV and DV symbolize. This is not true.
