## 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
