Answer:
Mean: 16.
Step-by-step explanation:
—Mean—
13 14 14 16 16 16 16 18 18 19
Simply start by adding the numbers together.
13 + 14 + 14 + 16 + 16 + 16 + 16 + 18 + 18 + 19
= 160.
Then divide it by how many numbers there are. Which is 10.
160 divided by 10 = 16.
—MAD—
Subtract each number by the mean.
|13-16| + |14-16| + |14-16| + |16-16| + |16-16| +|16-16| + |16-16| + |18-16| + |18-16| + |19-16|
Negatives don’t matter, everything should be positive numbers.
3 + 2 + 2 + 0 + 0 + 0 + 0 + 2 + 2 + 3
= 16
16 divided by 16 (amount of numbers).
MAD = 1
–IQR—
Seperate both sides in half.
|13 14 14 16 16| |16 16 18 18 19|
Take the median of each group.
Group 1:
|13 14 (14) 16 16|
This one is 14.
Group 2:
|16 16 (18) 18 19|
This one is 18.
Now take (number from group 2) 18 and subtract by (number from group 1) 14.
18 - 14 = 4
IQR = 4.
