In the data set below, what are the lower quartile, the median, and the upper quartile? 1, 1, 1, 3, 4, 9, 9 lower quartile = _____ median = _____ upper quartile = _____

Identify Median: Identify the median of the data set 1, 1, 1, 3, 4, 9, 9. Since there are 7 numbers, the median is the fourth number. Calculation: Median = 3 Determine Lower Quartile: Determine the lower quartile. Consider the first half of the data set, excluding the median: 1, 1, 1. Since there are 3 numbers, the lower quartile is the second number. Calculation: Lower quartile = 1 Determine Upper Quartile: Determine the upper quartile. Consider the second half of the data set, excluding the median: 4, 9, 9. Since there are 3 numbers, the upper quartile is the second number. Calculation: Upper quartile = 9

Identify Median: Identify the median of the data set $1, 1, 1, 3, 4, 9, 9$ . Since there are $7$ numbers, the median is the fourth number. Calculation: Median $= 3$
Determine Lower Quartile: Determine the lower quartile. Consider the first half of the data set, excluding the median: $1, 1, 1$ . Since there are $3$ numbers, the lower quartile is the second number. Calculation: Lower quartile $= 1$
Determine Upper Quartile: Determine the upper quartile. $\newline$ Consider the second half of the data set, excluding the median: $4, 9, 9$ . $\newline$ Since there are $3$ numbers, the upper quartile is the second number. $\newline$ Calculation: Upper quartile $= 9$
