1

What is a linear regression?

Where there is one continuous predictor variable

2

What is B0?

The intercept, where the line meets the Y axis

3

What is B1?

The slope, the angle of the regression line

4

What is the equation for regression as a predictive tool?

Y = B0 + (B1 * X) + (any other predictors)

5

What are zero order correlations?

Whether there are significant correlations between each individual predictor variable and the outcome

6

What is the adjusted R squared?

the amount of variance explained by the overall model

7

What does the B value tell you??

Whether the direction is positive or negative

8

How do you analyse binary variables?

-The difference between the two groups are always going to be the same
-Regression tells you if the difference from one group to the other is a significant predictor of the outcome

9

What does the direction of the relationship depend on? (binary)

Depends on the order of coding
