Arrange Data Set: Arrange the data set in ascending order.Data set: −7,−5,−4,−4,−5,−5Arranged data set: −7,−5,−5,−5,−4,−4
Count Data Points: Determine the number of data points in the set.There are 6 data points in the arranged set.
Calculate Median: Since the number of data points is even 6, the median will be the average of the two middle numbers.The two middle numbers are the third and fourth numbers in the arranged set: −5 and −5.
Find Average: Calculate the average of the two middle numbers.Average of –5 and –5: (–5+−5)/2=−10/2=−5
