Find the mean median and interquartile for the data set below

17,23,8,5,9,16,22,11,13,15,17,18

mean = 14.5 ; median = 15.5 ; interquartile = 7.5

Step-by-step explanation:

Given : 17,23,8,5,9,16,22,11,13,15,17,18.

To find : Find the mean median and interquartile for the data set .

Solution : We have given 17,23,8,5,9,16,22,11,13,15,17,18.

First we arrange in ascending order 5 , 8 ,9 ,11, 13, 15, 16 , 17, 17,18, 22, 23,

Mean : .

Mean :  .

Mean : 14.5

Median : Average of middle two numbers

Median :  .

Median :  .

Median : 15 .5

Interquartile  : median of lower half  - median of upper half.

Interquartile  :  - .

Interquartile  :  17.5 - 10= 7.5

Therefore, mean = 14.5 ; median = 15.5 ; interquartile = 7.5

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
