Arrange Data in Ascending Order: Arrange the data set in ascending order.Data set: −9,−7,−6,−4,−2,−2,−2,0We need to sort the numbers from the smallest to the largest to find the median.Sorted data set: −9,−7,−6,−4,−2,−2,−2,0
Determine Number of Data Points: Determine the number of data points.Count the total number of values in the sorted data set.There are 8 values in the data set.
Find the Median: Find the median.Since there is an even number of data points (8), the median will be the average of the 4th and 5th values in the sorted list.The 4th value is −4, and the 5th value is −2.
Calculate Average: Calculate the average of the 4th and 5th values.Median = (−4+−2)/2Median = (−6)/2Median = −3
