Bianca369:

no the median is between 23-25 and if you meet in the middle it is 24

add them all up then divide by the number of numbers there are so you add them and then divide the number you get by 5 in this case

The range is 39. Explanation: To find the range all you need to do is take the hugest number and subtract it with the smallest number. So, your equation is 60 minus 21, which equals 39. I hope I helped you okay :)
