Q. In the data set below, what are the lower quartile, the median, and the upper quartile?49,49,53,89,89,98lower quartile=__median=__upper quartile=__
Arrange Data Set: Arrange the data set in ascending order if it is not already sorted.The given data set is already in ascending order: 49,49,53,89,89,98.
Find Median: Find the median of the data set.Since there are 6 numbers, the median will be the average of the 3rd and 4th numbers.Median =(53+89)/2=142/2=71.
Identify Lower Quartile: 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 is a single number. Since we have an even number of data points, we will include the lower middle value in the first half.First half is 49, 49, 53.
Find Lower Quartile: Find the value of the lower quartile.The lower quartile is the median of the first half of the data set.Since there are 3 numbers in the first half, the lower quartile is the middle number, which is 49.
Identify Upper Quartile: 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 is a single number. Since we have an even number of data points, we will include the upper middle value in the second half.Second half is 89, 89, 98.
Find Upper Quartile: Find the value of the upper quartile.The upper quartile is the median of the second half of the data set.Since there are 3 numbers in the second half, the upper quartile is the middle number, which is 89.
Write Quartile Values: Write the values of the lower quartile, median, and the upper quartile.Lower quartile = 49Median = 71Upper quartile = 89
