data set: 1, 7, 5, 3, 4, 4
mean is m: (1 + 7 + 5 + 3 + 4 + 4) ÷ 6 = 24 / 6 = 4
3,2,4,2,3,3, and p
m - 1 = (3 + 2 + 4 + 2 + 3 + 3 + p) / 7
4 - 1 = (17 + p)/7
3 * 7 = 17 + p
21 - 17 = p
4 = p
2, 2, 3, 3, 3, 4, 4 ⇒ median q is 3.
m = 4 ; p = 4 ; q = 3.
mean is m: (1 + 7 + 5 + 3 + 4 + 4) ÷ 6 = 24 / 6 = 4
