Arrange in ascending order: Data set: 1,2,5,4,0,0,1,4,8First, we need to arrange the data set in ascending order to find the median.
Count data points: Arranging the data set in ascending order: 0,0,1,1,2,4,4,5,8
Calculate median position: Count the number of data points in the set.There are 9 numbers in the data set.
Identify middle number: Since the number of data points is odd, the median will be the middle number.To find the middle number, use the formula: (n+1)/2, where n is the number of data points.(9+1)/2=10/2=5The median is the 5th number in the ordered set.
Find median: Identify the 5th number in the ordered set.The 5th number in the ordered set is 2.
Find median: Identify the 5th number in the ordered set.The 5th number in the ordered set is 2.The median of the given data set is 2.
