Answer:
2.42
Step-by-step explanation:
First, we need to find the mean
Add up all the number
1+6+5+8+3+7+1+4+10+9 = 54
Count up all the numbers (found in data)
10
Then, divide
54/10 = 5.4
Then find the absolute difference between each point and the mean and sum them together and divide by the number of points
((5.4-1)+(5.4-6)+(5.4-5)+(8-5.4)+(5.4-3)+(7-5.4)+(5.4-1)+(5.4-4)+(10-5.4)+(5.3-9)) ÷ 10
24.2 ÷ 10 = 2.42
2.42
