Statistics I ? First Analysis Project

You are part of a research team that is studying academic motivation in high school students. A question has arisen regarding the strength of the relationship between academic motivation and achievement. Some members of the team believe there is a strong positive relationship between academic motivation and achievement, while others don?t think the two variables are related much, if at all.

To provide some information relevant to this discussion, a small study was designed. A random sample of 50 high school seniors from the local school district agreed to participate. Each student filled out a measure of academic motivation and released his/her SAT-math scores to the researchers. The data for this study are provided on the following page.

The measure of academic motivation was the Peabody Academic Motivation Scale (PAMS). Studies of the reliability and validity of scores obtained from using this instrument have been favorable when the instrument was used with high school students. The possible scores range from 0 to 100. The SAT-math scores can range from 200 to 800 and have also been shown to be reasonably reliable and valid in previous studies.

For this project you should:

1. Analyze each of the variables individually (mean, SD, skewness, kurtosis)
2. Analyze the relationship between the two variables (scatterplot and correlation)
3. Write a one or two paragraph summary of the results

Please turn in (1) the summary, (2) the program, and (3) the output.
