For the regression equation, Y = 3X + 8, what can be determined about the correlation between X and Y?

A set of n = 5 pairs of X and Y scores has SX = 15, SY = 5, and SXY = 10. For these data, what is the value of SP?

Consider the following data table. What is the correct value for the F ratio? Note, you will also need MSwithin treatments.                 Treatment 1                 Treatment 2                  Treatment 3   4 0 1

The correlation coefficient is a reasonable explanation for the causal relationship between two variables.

If there is a positive correlation between X and Y, then the regression equation Y = bX + a will have _____.

One or two extreme data points can have a dramatic effect on the size of a correlation.

For an independent-measures ANOVA comparing four treatment conditions, dfbetween = 3.

The chi-square test for independence is most like a non-parametric version of which of the following parametric statistics?

Suppose that there is a correlation of r = 0.41 between the amount of time that each student reports studying for an exam and the student’s grade on the exam. This correlation would mean that there is a tendency for people who study more to get better grades.

Post tests are only needed if H0 is rejected in an ANOVA comparing more than two treatments.
