Practice calculations Dataset 1 Dog agility is a sport where trainers guide their dogs through an obstacle course as quickly as possible. Two trainers, Abby and Lauren, have dogs participating in agility competitions. Each dog completes the same agility Insite course, and they measure the time it takes each dog to complete the course (in seconds). Leurun Times for Abby's three dogs were 30, 40, and 50. 20 30 Times for Lauren's three dogs were 50, 60, and 70. 40 50 TO 90 Time [in seconds) 1. Calculate the Sum of Squares Total (SST). 2. Calculate the Sum of Squares Error (SSE). 3. Calculate the Sum of Squares Groups (SSG). 4. What do you notice about the relationship between the three numbers you calculated? Dataset 2 What if we changed the numbers? Times for Abby's three dogs were 20, 40, and 60. Times for Lauren's three dogs were 40, 60, and 80.
