Let's consider an example involving a study on the effects of three different exercise programs (A, B, and C) on participants' heart rate. We'll compare the heart rates at three different time points: pre-exercise, immediately post-exercise, and 30 minutes post-exercise.
Here's a table representing the data for three participants:
To calculate the values for the table, we follow these steps:
Calculate the overall mean:
Mean Pre-Exercise = (75 + 80 + 70) / 3 = 75
Mean Post-Exercise = (120 + 130 + 125) / 3 = 125
Mean 30min Post-Exercise = (85 + 90 + 80) / 3 = 85.
Calculate the Sum of Squares (SS):
Calculate the Degrees of Freedom (df):
Calculate the Mean Squares (MS):
Calculate the F-ratio (F):
Calculate the p-value:
Final Table will look like:
