Calculate quartiles and interquartile range

Full solution

Q. In the data set below, what are the lower quartile, the median, and the upper quartile?

\newline

1, 1, 2, 2, 2, 4, 4, 7, 8, 8, 8

\newline

lower quartile

\_\_

\newline

median

=

\_\_

\newline

upper quartile

=

\_\_

Identify the Median: Step $1$ : Identify the median of the data set $1, 1, 2, 2, 2, 4, 4, 7, 8, 8, 8$ . Since there are $11$ numbers, the median is the $6$ th number. Calculation: Median $= 4$
Determine Lower Quartile: Step $2$ : Determine the lower quartile. $\newline$ Consider the first half of the data set, excluding the median: $1, 1, 2, 2, 2$ . $\newline$ Since there are $5$ numbers, the lower quartile is the $3$ rd number. $\newline$ Calculation: Lower quartile $= 2$
Determine Upper Quartile: Step $3$ : Determine the upper quartile. $\newline$ Consider the second half of the data set, excluding the median: $4, 7, 8, 8, 8$ . $\newline$ Since there are $5$ numbers, the upper quartile is the $3$ rd number. $\newline$ Calculation: Upper quartile $= 8$
