Question

PLEASE HELP ME I REALLY NEED HELP

Answer 1

a) mean: add all numbers and then divide them.. so:

3+9+10+5+8+5+9+11+10+3+10= 83

83 divided by 11 = 83/11 or 7 4/11

b) median: the middle number of the sequence but put in order first.. so:

smallest to largest: 3,3,5,5,8,9,9,10,10,10,11

so then middle number: 9

c) mode: most frequent (popular) figure/number.. so:

most frequent value: 10

d) range: difference between smallest number and largest number

so in this case: 11-3 = 8

e) positive direction
