Given data,
A researcher hypothesizes that plants given Plant Food A, Plant Food B, or Plant Food C will grow to different heights



The total sample size is    . Therefore, the total degrees of freedom are:
  
Also, the between groups degrees of freedom are    , and the within-
groups degrees of freedom are
  
First, we need to compute the total sum of values and the grand mean. The following is
obtained
  
Also, the sum of squared values is
  
Based on the above calculations, the total sum of squares is computed as follows
