Regression
- Regression: Correlation + Prediction
- predicting y based on x
- e.g., predicting….
- Maximal Hear Rate, HRmax (y)
- based on Age (x)
- Regression equation
- y' = bx + a; e.g., HRmax = 220 - Age
- plug in an x value (Age) to predict y (HRmax)
- Note
- y = actual value of a score
- y' = predict value
