Why 17 decide by 6?wasn't it 6.5 6:09

[@Itz_AdiZ]

6 was the amount of numbers in the data set, we had 3.5, 3.5, 1.5, 1.5, 5.5, and 1.5 so 6 numbers if u add those 6 numbers up u get 17 and divide that by 6, idk if you know how to find average but its almost the same formula! :D

[@murugesanram7560]

I did not know this when my teacher was explaining this

yo, in class the teacher/the book said that we needed to subtract the number of points by 1 and divide 17 (or whatever number you get when you add the deviations) by that number, is he correct?
