What is the median of the following numbers? 12,15,93,32,108,22,16,21

  • A. 22
  • B. 21.5
  • C. 21
  • D. 8

Correct Answer: B. 21.5

Explanation

To find the median, first you arrange the numbers in order from least to greatest. Then you count how many numbers you have and divide that number by two. In this case (12,15,16,21,22,32,93,10)/8= 8 numbers. So 8/2=4 Then starting from the least side of the numbers count 4 numbers till you reach the median number of 21 Then starting from the greatest side count 4 numbers until you reach the other median number of 22 Finally find the mean of the two numbers by adding them together and dividing them by two (21+22)/2=43/2 to find the median number of 21.5.
