In the data set below, what are the lower quartile, the median, and the upper quartile? 3, 5, 6, 8, 8, 9 lower quartile = _____ median = _____ upper quartile = _____

Arrange and Find Median: Arrange the data set in ascending order and find the median. The data set is already in ascending order: 3, 5, 6, 8, 8, 9. Since there are 6 numbers, the median will be the average of the 3rd and 4th numbers. Median: (6 + 8) / 2 = 14 / 2 = 7.Identify 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 not part of the data points. First half is 3, 5, 6. Lower quartile data: 3, 5, 6.Find Lower Quartile Value: Find the value of the lower quartile. Lower quartile data: 3, 5, 6. For an odd number of observations, the lower quartile is the middle number. Lower quartile is 5.Identify 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 not part of the data points. Second half is 8, 8, 9. Upper quartile data: 8, 8, 9.Find Upper Quartile Value: Find the value of the upper quartile. Upper quartile data: 8, 8, 9. For an odd number of observations, the upper quartile is the middle number. Upper quartile is 8.Write Quartile Values: Write the values of the lower quartile, median, and the upper quartile. Lower quartile = 5 Median = 7 Upper quartile = 8

Arrange and Find Median: Arrange the data set in ascending order and find the median. $\newline$ The data set is already in ascending order: $3, 5, 6, 8, 8, 9$ . $\newline$ Since there are $6$ numbers, the median will be the average of the $3$ rd and $4$ th numbers. $\newline$ Median: $(6 + 8) / 2 = 14 / 2 = 7$ .
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 not part of the data points. $\newline$ First half is $3$ , $5$ , $6$ . $\newline$ Lower quartile data: $3$ , $5$ , $6$ .
Find Lower Quartile Value: Find the value of the lower quartile. $\newline$ Lower quartile data: $3, 5, 6$ . $\newline$ For an odd number of observations, the lower quartile is the middle number. $\newline$ Lower quartile is $5$ .
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 not part of the data points. $\newline$ Second half is $8, 8, 9$ . $\newline$ Upper quartile data: $8, 8, 9$ .
Find Upper Quartile Value: Find the value of the upper quartile. $\newline$ Upper quartile data: $8, 8, 9$ . $\newline$ For an odd number of observations, the upper quartile is the middle number. $\newline$ Upper quartile is $8$ .
Write Quartile Values: Write the values of the lower quartile, median, and the upper quartile. $\newline$ Lower quartile = $5$ $\newline$ Median = $7$ $\newline$ Upper quartile = $8$
