Arrange Data Set: Arrange the data set in ascending order.Data set: 2,8,−1,3,−2,8,6Arranged data set: −2,−1,2,3,6,8,8
Count Data Points: Determine the number of data points.There are 7 numbers in the data set.
Find Median Position: Find the position of the median. Since there is an odd number of data points, the median will be the middle number. For 7 data points, the median is the 4th number (since (7+1)/2=4).
Identify Median: Identify the median.The 4th number in the arranged data set is 3.
Verify Calculation: Verify the calculation.The data set is correctly arranged in ascending order, and the middle position for an odd number of data points is correctly identified. The 4th number is indeed 3, which is the median.
