1 Correlated Variables:

In this study, I used Fhealth.sav data file.

I tried to investigate whether there is a correlation between weight and systolic blood pressure.

The correlation between age and pulse rate is .618. There is a moderate and positive relationship between these two variables. The correlation coefficient is significant at 0.01 level.

1. Compare the different Year in School for students in the Stat_Grades.sav dataset to determine if there is a statistically significant difference in the average Final Exam Points between the different years (first year, sophomore, junior, senior). Be sure to state the hypothesis, state Ho and Ha, include and explain all SPSS results, and write final conclusions for the full results of the test. Include Post Hoc results and the plot. Be sure that your final conclusions are written in common terms for an average person to understand.

(a) What is the hypothesis being tested?
Research question: whether there is a statistically significant difference in the average Final Exam Points between the different years (first year, sophomore, junior, senior).

(b) What are Ho and Ha?
Ho: There is no statistically significant difference in the average Final Exam Points between the different years (mean of first year = mean of sophomore = mean of junior = mean of senior)
Ha: There is a statistically significant difference in the average Final Exam Points between the different years (mean of first year NOT = mean of sophomore OR NOT= mean of junior OR NOT = mean of senior) (AT LEAST ONE OF THEM IS DIFFERENT)

(c) What statistical test will you run - and include all the SPSS outputs (including the plot and post hoc)?

ONE WAY ANOVA

Limit of (cos pi/3)(cos pi/4)...(cos pi/n) as n approaches infinity
