Question

The number of regular seasons wins for 10 football teams in a given season are bellow. Determine the range,mean, variance, and standard deviation of 2,10,15,3,12,7,13,6,3,10

Answer 1

Answer:

Step-by-step explanation:

Range is calculated by the highest value in a given data set - lowest value

Given the data set above, the highest value is 15, while the lowest value is 2

To calculate range, we insert the values into the formula:

Range = 15 - 2 = 13

2) To calculate mean, we sum the total of all values in the data set and divide by the number of values

Mean = 2+ 10 +15+ 3+12+7+13+6+3+10/10

= 83/10 = 8.3
