Find mean of group A and B (tenth) and find their difference
Can you do it like a 7th grader
Sure!
First, let's find the mean of group A:
Group A: 8, 5, 7, 10, 9
Step 1: Add the numbers together
8 + 5 + 7 + 10 + 9 = 39
Step 2: Divide the sum by the total number of numbers (5 in this case)
39 / 5 = 7.8
So, the mean of group A is 7.8
Now let's find the mean of group B:
Group B: 12, 14, 16, 10, 18
Step 1: Add the numbers together
12 + 14 + 16 + 10 + 18 = 70
Step 2: Divide the sum by the total number of numbers (5 in this case)
70 / 5 = 14
So, the mean of group B is 14
Now, let's find the difference between the mean of group A and B:
14 - 7.8 = 6.2
Therefore, the difference between the mean of group A and B is 6.2.
Can you make it shorter?
Sure!
The mean of group A is 7.8 and the mean of group B is 14.
The difference between the two means is 6.2.
