In the data set below, what are the lower quartile, the median, and the upper quartile? 1, 3, 5, 6, 7, 7, 9 lower quartile = _____ median = _____ upper quartile = _____

Identify the Median: Step 1: Identify the median of the data set 1, 3, 5, 6, 7, 7, 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: 1, 3, 5 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: 7, 7, 9 Calculation: Upper quartile = 7

Identify the Median: Step $1$ : Identify the median of the data set $1, 3, 5, 6, 7, 7, 9$ . 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: $1, 3, 5$ $\newline$ 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: $7, 7, 9$ $\newline$ Calculation: Upper quartile $= 7$
