Arrange Data in Ascending Order: Arrange the data set in ascending order.Data set: 9, −7, −1, −4, 3, 6Arranged data set: −7, −4, −1, 3, 6, 9
Count Data Points: Determine the number of data points.There are 6 data points in the arranged set.
Find the Median: Find the median.Since the number of data points is even 6, the median will be the average of the 3rd and 4th numbers in the ordered set.The 3rd number is –1 and the 4th number is 3.
Calculate Median: Calculate the average of the 3rd and 4th numbers.Median = (−1+3)/2Median = 2/2Median = 1
