In the data set below, what are the lower quartile, the median, and the upper quartile? 2, 3, 4, 6, 9, 9, 9 lower quartile = _____ median = _____ upper quartile = _____

Identify the median: Step 1: Identify the median of the data set 2, 3, 4, 6, 9, 9, 9. Since there are 7 numbers, the median is the fourth number. Calculation: Median = 6 Determine lower quartile: Step 2: Determine the lower quartile. The lower quartile is the median of the first half of the data set (excluding the median of the entire set). First half: 2, 3, 4 Calculation: Lower quartile = 3 Determine upper quartile: Step 3: Determine the upper quartile. The upper quartile is the median of the second half of the data set (excluding the median of the entire set). Second half: 9, 9, 9 Calculation: Upper quartile = 9

Identify the median: Step $1$ : Identify the median of the data set $2, 3, 4, 6, 9, 9, 9$ . Since there are $7$ numbers, the median is the fourth number. Calculation: Median $= 6$
Determine lower quartile: Step $2$ : Determine the lower quartile. $\newline$ The lower quartile is the median of the first half of the data set (excluding the median of the entire set). $\newline$ First half: $2, 3, 4$ $\newline$ Calculation: Lower quartile $= 3$
Determine upper quartile: Step $3$ : Determine the upper quartile. $\newline$ The upper quartile is the median of the second half of the data set (excluding the median of the entire set). $\newline$ Second half: $9, 9, 9$ $\newline$ Calculation: Upper quartile $= 9$
