Q. In the data set below, what are the lower quartile, the median, and the upper quartile?1,2,2,5,6,6,9lower 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: 1,2,2,5,6,6,9.Since there are 7 numbers, the median is the middle number, which is the fourth number in the list.Median: 5
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.First half is 1,2,2.Lower quartile data: 1,2,2
Find Lower Quartile Value: Find the value of the lower quartile.Lower quartile data: 1,2,2For an odd number of observations, the median is the middle number.Lower quartile is 2.
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.Second half is 6,6,9.Upper quartile data: 6,6,9
Find Upper Quartile Value: Find the value of the upper quartile.Upper quartile data: 6,6,9For an odd number of observations, the median is the middle number.Upper quartile is 6.
Write Quartile Values: Write the values of the lower quartile, median, and the upper quartile.Lower quartile = 2Median = 5Upper quartile = 6
