Suppose you are a product engineer for a tool manufacturing company, and want to investigate the strength of several new prototype redesigns of one of your drills. You have 13 new drill designs and would like to include a control group also of the original drill design. Your  firm has decided to sample 37 drills for each new drill design and 37 drills in the control group with the original design. Using this information, if you were to conduct an ANOVA test based on a quantitative measure of the drill's performance, what is the degree of freedom associated with the variation within groups (SSE) in this analysis
