Q. In the data set below, what are the lower quartile, the median, and the upper quartile?3,4,5,5,5,7,8,8,9,9lower quartile=__median=__upper quartile=__
Identify Median Calculation: Step 1: Identify the median of the data set 3,4,5,5,5,7,8,8,9,9. Since there are 10 numbers, the median will be the average of the 5th and 6th numbers. Calculation: (5+7)/2=6.
Lower Quartile Data Set: Step 2: 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 3,4,5,5,5.Lower quartile data: 3,4,5,5,5.
Find Lower Quartile Value: Step 3: Find the value of the lower quartile.Since there are 5 numbers in the lower quartile data, the lower quartile is the middle number.Calculation: The third number is 5.
Upper Quartile Data Set: Step 4: 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 7,8,8,9,9.Upper quartile data: 7,8,8,9,9.
Find Upper Quartile Value: Step 5: Find the value of the upper quartile.Since there are 5 numbers in the upper quartile data, the upper quartile is the middle number.Calculation: The third number is 8.
