Answer 3

I think it's b.

Answer 4

Let's use the online mean (arithmetic average) calculator for this.

We will have to type in the data from the chart.

This will be done twice. Once for the Group A data and once for the Group B data.

Answer 5

I am not into guessing answers. So, let's calculate the means.

Answer 6

Are you okay with that? You can calculate by hand if you like.

Answer 7

yes I am ok with that

Answer 8

I'm going over to the online calculator. I'll be back to compare answers with you for the means.

Answer 9

What did you get for the Group A mean?

What did you get for the Group B mean?

Answer 10

i got 2

Answer 11

2 for what?

Answer 12

Do not round the result.

Answer 13

i mean i got 1 for group b and 2 for group a

Answer 14

That sounds as if you did not use the calculator and are guessing.

Answer 15

Just add up the numbers and divide by the number of scores.

Those answers are not correct and neither is option B correct as far as I can tell.

Answer 16

okay let me do that hold on

Answer 17

i got 2 again

Answer 18

2 for which group?

Answer 19

@tabpernick

Answer 20

(1 + 1.5 + 3.03 + 3.2 + 2.8 + 1.5 + 1.8 + 2.5 +2.2)/9=

(2+2.5+3.23+1.3+1.8+2.4+3+1.5+1.8)/9 =

I don't get 2 for either of these. Do you see my error?

Answer 21

for you first one i'm still getting 2.17

Answer 22

Yes. Note that 2.17 is not the same as 2.

Answer 23

The second group has a mean of what?

Answer 24

Sorry :( for beign so frustrating anyway so the answer is choice a?

Answer 25

The mean of the second group is 2.17 so yes, option A.
