Question

33. What are the minimum, first quartile, median, third quartile, and maximum of the data set?

18, 20, 11, 10, 8, 6, 12, 4

Answer 1

First put the data in ascending order:
4, 6, 8, 10, 11, 12, 18, 20
Now you can easily find the minimum and maximum.
The median is the value halfway between the two values either side of themiddle,
\[\frac{1}{2}\times (10+11)=\]
Next partition the data into two equally sized sub-sets:
{4, 6, 8, 10} and {11, 12, 18, 20}
The lower quartile is the median of the first of the two sub-sets,
\[\frac{1}{2}\times (6+8)=?\]
The upper quartile is the median of the second of the two sub-sets,\[\frac{1}{2}\times (12 +18)=\]
