Arrange Data Set: Arrange the data set in ascending order.To find the median, we first need to sort the numbers from smallest to largest.
Sort Data Set: Sorting the data set.The sorted data set is: 1.2, 2.2, 3.1, 5.7, 8.4, 9.8
Determine Median Position: Determine the position of the median. Since there are 6 numbers in the data set, the median will be the average of the 3rd and 4th numbers.
Calculate Median: Calculate the median.The 3rd number is 3.1 and the 4th number is 5.7. The median is the average of these two numbers: (3.1+5.7)/2
Perform Calculation: Perform the calculation.Median = (3.1+5.7)/2=8.8/2=4.4
