Highlight 4 assumptions pertaining to regression:
- Scatter plot pattern is reasonably straight (Linearity)
- No points lie far enough away to pull the line of best fit away from the main point pattern (Influence).
- The plot does not fan out as x increases or decreases (Equal Spread)
- Predict Y at a value of X within the range of the X data (Interpolation)
- Predict Y at a value of X outside the range of the X data (Extrapolation)
- The observations are independent (Independence)
