Answer 1

For example

1, 2, 3, 4, 5

What's the minimum number in the set?

Answer 2

1?

Answer 3

Right, because it's the smallest.
So maximum would be the largest

Answer 4

For range, you need to do an operation (add, subtract, multiply, or divide) with the maximum and minimum. Any idea?

Answer 5

hmm.. subtract?

Answer 6

Yep
Range = Maximum - Minimum

Lets do those 3 and see if we can eliminate some answer choices

Answer 7

Okay! I got 7.2 - 2.4 = 4.8

Answer 8

Cool!

Maximum = 7.2
Minimum = 2.4
Range = 4.8

Answer 9

yayyy!

Answer 10

The median, i have trouble with XD

Answer 11

So that leaves A and D I guess

Answer 12

yepp!

Answer 13

For median, lets first put all the numbers in order from greatest to least

Answer 14

Okay! I know the mean is 39.5 divided by 8 = 4.9375

And here is the median:

2.4, 2.6, 4.1, 5.5, 5.5, 6.1, 6.1, 7.2

So, the median is 5.5!

The answer is D?

Answer 15

Yep, nice job on the mean also

Answer 16

Thank you!
