Q. In the data set below, what are the lower quartile, the median, and the upper quartile?\newline20,20,20,36,40,40,56,59,66,80,9120, 20, 20, 36, 40, 40, 56, 59, 66, 80, 91\newlinelower quartile==__\_\_\newlinemedian==__\_\_\newlineupper quartile==__\_\_
  1. Arrange Data Set: Arrange the data set in ascending order if it is not already sorted.\newlineThe given data set is already in ascending order: 20,20,20,36,40,40,56,59,66,80,9120, 20, 20, 36, 40, 40, 56, 59, 66, 80, 91.
  2. Find Median: Find the median of the data set.\newlineThere are 1111 numbers in the data set, so the median will be the middle number, which is the 66th number in the sorted list.\newlineThe median is 4040.
  3. Identify Lower Quartile: Identify the data set for the lower quartile.\newlineFor the lower quartile, consider the first half of the data set, excluding the median if it is a part of the data.\newlineThe first half is 20,20,20,36,4020, 20, 20, 36, 40 (the first five numbers).
  4. Find Lower Quartile: Find the value of the lower quartile.\newlineSince there are 55 numbers in the first half, the lower quartile will be the median of these 55 numbers, which is the 33rd number.\newlineThe lower quartile is 2020.
  5. Identify Upper Quartile: Identify the data set for the upper quartile.\newlineFor the upper quartile, consider the second half of the data set, excluding the median if it is a part of the data.\newlineThe second half is 40,56,59,66,80,9140, 56, 59, 66, 80, 91 (the last six numbers).
  6. Find Upper Quartile: Find the value of the upper quartile.\newlineSince there are 66 numbers in the second half, the upper quartile will be the average of the 33rd and 44th numbers in this half.\newlineThe upper quartile is the average of 5959 and 6666.\newline(59+66)/2=125/2=62.5(59 + 66) / 2 = 125 / 2 = 62.5\newlineThe upper quartile is 62.562.5.
