Answer in Statistics and Probability for Khuts1o #89042

Data set “=66,48,59,89,67,79”

Reordered “=48,59,66,67,79,89”

“n=6”

“median={66+67 over 2}=66.5”

There is no mode for this data set.

The first quartile (or lower quartile or 25th percentile) is the median of the bottom half of the numbers. 

So, the bottom half is 48,59,66.

“lower quartile=59.”

The third quartile (or upper quartile or 75th percentile) is the median of the upper half of the numbers.

So, the upper half is 67,79,89.

“upper quartile=79.”

The interquartile range (IQR) is the difference between the upper and lower quartiles.

“IQR=79-59=20”

The interquartile range “=20.”
