SS (sum of squares) for between-groups variation is missing, but it can be calculated using the formula: total SS - within-groups SS.

total SS = 2113.833 
within-groups SS = 1483

Substituting these values in the formula, we get:

between-groups SS = 2113.833 - 1483 = 630.833

Therefore, the answer is B) 630.83.
