Interpreting Regression Analysis Flashcards

1

represents the predicted change in the y - variable for a one unit increase in the x - variable

2

the residual plot must show this to suggest linear regression is the appropriate analysis

3

This is the predicted y variable value when the x-variable is 0.

4

this plot helps to determine if linear regression is appropriate for the data

5

The y-variable is predicted to inc/dec by this amount for each additional unit in x - variable

6

percent of variation in the y-variable explained by the linear model relating x and y

7

found by doing: actual y - predicted y

8

a value that shows how much the regression line under-/over-predicted the actual amount

9

If you square root the percent of variation, then you will get this value.

10

A value to determine the strength of the linear relationship between two quantitative variables
