Answer:
Mean: 12.6
Median: 12
Mode: No Mode
Step-by-step explanation:
First of all, put in ranking from smallest to largest.
9, 10, 12, 15, 17
Mean:
You add all the numbers up then divide by the <u>amount</u> of numbers.
9 + 10 + 12 + 15 + 17 = 63
5 numbers
63 / 5 = 12.6
Median:
What number is in the middle?
Because there's an odd amount of numbers, we can find the number in the middle. To do this you need to cancel out from the left to the right, until you get to the middle.
12
Mode:
For this you need to find a number that is recurring the most. But with the numbers that you were given here; there was no number that is repeated more than twice. So for this you would say 'No Mode'.
