❖ The median of the data is 23.
You keep crossing out numbers until you get to the middle point. First, you cross of the beginning and the end which is 21 and 25. You then cross out 22 and 24. The remaining number is 23. When you are working with an even amount of numbers, you are left with 2 numbers so you add those 2 numbers and divide by 2.
