Calculate the Repeated Measures ANOVA using the following data. Trial 1 Trial 2 Trial 3 643 469 484 655 427 456 702 525 402
I need to know what x-bar, SS, Σx2 and so that I can solve the problem. I already know what T, n, k, N, and G are.
Obtain the mean value (x-bar) for each of the 3 treatments:
The value of x-bar for trial 1 is obtained as given below:
Thus, the value of x-bar for trail-1 is 666.6667.
The value of x-bar for trial 2 is obtained as given below:
Thus, the value of x-bar for trail-2 is 473.6667.
The value of x-bar for trial 3 is obtained as given below:
Thus, the value of x-bar for trail-3 is 447.3333.
Obtain the value of sum of squares (SS) for each of the 3 treatments:
The value of sum of squares (SS) for trial 1 is obtained as given below:
Thus, the value of sum of squares (SS) for trial 1 is SS1 = 1,944.6667.
The value of sum of squares (SS) for trial 2 is obtained as given below:
Thus, the value of sum of squares (SS) for trial 2 is SS2 = 4,834.6667.
The value of sum of squares (SS) for trial 3 is obtained as given below:
Thus, the value of sum of squares (SS) for trial 3 is SS3 = 3,474.6667.
