Question

PLEASE HELP SOMEONE ANSWER THIS FOR ME AND PLEASE BE CORRECT IT'S DUE RN

The table shows the number of goals made by two hockey players.


Player A Player B
2, 1, 3, 8, 2, 1, 4, 3, 1 2, 3, 1, 3, 2, 2, 1, 3, 6


Find the best measure of variability for the data and determine which player was more consistent.
Player A is the most consistent, with an IQR of 2.5.
Player B is the most consistent, with an IQR of 1.5.
Player A is the most consistent, with a range of 7.
Player B is the most consistent, with a range of 5.

Answer 1

The answer to your problem is, B. Player B is the most consistent, with an IQR of 1.5.

Explanation:

Steps in which we need to answer

1. We then add up all of these values.
2. Then divide the result by the quantity of numbers.
3. Then calculate its square root.

We know the first table be represented as A.

A = { 2 , 1 , 3 , 8 , 2 , 1 , 4 , 3 , 1 }

mean of A = 25/9 = 2.778

We know the second table be represented as B.

B = { 2 , 3 , 1 , 3 , 2 , 2 , 1 , 3 , 6 }

mean of B = 23/9 = 2.5556

The standard deviation of B = 1.5

Which can conclude to the answer.

Thus the answer to your problem is, B. Player B is the most consistent, with an IQR of 1.5.
