Q. In the data set below, what are the lower quartile, the median, and the upper quartile?5,6,7,9,9,9lower quartile=__median=__upper quartile=__
Arrange data set, find median: Step 1: Arrange the data set in order and find the median.Data set: 5,6,7,9,9,9.Since there are 6 numbers, the median is the average of the 3rd and 4th numbers.Calculation: (7+9)/2=8.
Identify lower quartile data: Step 2: Identify the data set for the lower quartile.For the lower quartile, consider the first half of the data set.First half: 5,6,7.Lower quartile is the median of this subset.Calculation: Median of 5,6,7 is 6.
Identify upper quartile data: Step 3: Identify the data set for the upper quartile.For the upper quartile, consider the second half of the data set.Second half: 9,9,9.Upper quartile is the median of this subset.Calculation: Median of 9,9,9 is 9.
