Textbook Problem

**a.** A researcher computes the regression equation for a sample of *n* = 25 pairs of scores, *X* and *Y* values. If an analysis of regression is used to test the significance of the equation, what are the *df* values for the *F*-ratio?

**b.** A researcher evaluating the significance of a regression equation obtains an *F-ratio* with *df =* 1, 18. How many pairs of scores, *X* and *Y* values, are in the sample?

**a.**

To determine

The
d . f values for the *F*-ratio.

Explanation

**Given info:**

A researcher computes the linear regression equation for a sample of
*X* and *Y* values.

**Calculation:**

There are two

- Degree of freedom for regression which is 1.
- Degree of freedom for residual which is calculated as (n-2)

**b.**

To determine

The numbers of pairs of scores in the sample.
