How do I find my s2p?

When the group sizes are equal, the pooled variance reduces to s2p=(s21+s22)/2, which is the average of the two variances. Again, if all groups have the same number of observations, then the formula simplifies to Σki=1s2i/k, which is the average of the k variances.

What is S2P and procure to pay?
