Question

Explain how to use the regression calculator to make a reasonable prediction given a data table

Answer 1

Sample Answer: Given bivariate data, first determine which is the independent variable, x, and which is the dependent variable, y. Enter the data pairs into the regression calculator. Substitute the value for one variable into the equation for the regression line produced by the calculator, and then predict the value of the other variable.

Answer 2

Given data, first determine which is the independent variable, x, and which is the dependent variable, y. Enter the data pairs into the regression calculator. Substitute the value for one variable into the equation for the regression line produced by the calculator, and then predict the value of the other variable.

Explanation:

1. Enter data into the regression calculator.
2. Determine the regression equation.
3. Substitute the correct value for x or y into the equation.
4. Simplify to find the value of the other variable.
