In the data set below, what are the lower quartile, the median, and the upper quartile? 14, 25, 26, 26, 28, 46, 65, 66, 68, 71 lower quartile = _____ median = _____ upper quartile = _____

Arrange Data in Ascending Order: Arrange the data set in ascending order and list it out. Data set: 14, 25, 26, 26, 28, 46, 65, 66, 68, 71Find Median: Find the median of the data set. Since there are 10 numbers, the median will be the average of the 5th and 6th numbers. Median: (28 + 46) / 2 = 74 / 2 = 37Identify Lower Quartile Data: Identify the data set for the lower quartile. For the lower quartile, consider the first half of the data set, excluding the median if it's part of the data. First half: 14, 25, 26, 26, 28Find Lower Quartile Value: Find the value of the lower quartile. Since there are 5 numbers in the first half, the lower quartile will be the middle number. Lower quartile: 26Identify Upper Quartile Data: Identify the data set for the upper quartile. For the upper quartile, consider the second half of the data set, excluding the median if it's part of the data. Second half: 46, 65, 66, 68, 71Find Upper Quartile Value: Find the value of the upper quartile. Since there are 5 numbers in the second half, the upper quartile will be the middle number. Upper quartile: 66

Arrange Data in Ascending Order: Arrange the data set in ascending order and list it out. $\newline$ Data set: $14, 25, 26, 26, 28, 46, 65, 66, 68, 71$
Find Median: Find the median of the data set. $\newline$ Since there are $10$ numbers, the median will be the average of the $5$ th and $6$ th numbers. $\newline$ Median: $(28 + 46) / 2 = 74 / 2 = 37$
Identify Lower Quartile Data: Identify the data set for the lower quartile. $\newline$ For the lower quartile, consider the first half of the data set, excluding the median if it's part of the data. $\newline$ First half: $14, 25, 26, 26, 28$
Find Lower Quartile Value: Find the value of the lower quartile. $\newline$ Since there are $5$ numbers in the first half, the lower quartile will be the middle number. $\newline$ Lower quartile: $26$
Identify Upper Quartile Data: Identify the data set for the upper quartile. $\newline$ For the upper quartile, consider the second half of the data set, excluding the median if it's part of the data. $\newline$ Second half: $46, 65, 66, 68, 71$
Find Upper Quartile Value: Find the value of the upper quartile. $\newline$ Since there are $5$ numbers in the second half, the upper quartile will be the middle number. $\newline$ Upper quartile: $66$
