Jeremy is a snowboarder. one of his best tricks is catching big air, jumping off the ramp while holding on to the snowboard. jeremy did this trick 20 times, the heights (in meters) of which were {18, 23, 15, 16, 15, 17, 22, 16, 19, 11, 24, 14, 12, 16, 20, 18, 14, 13, 21, 11}. what is the median value of jeremy’s big air trick?

The median value is the middle value in a set of numbers under measure of central tendency. the set of numbers shall be arranged from smallest to largest. Arranging the given set, we have: 

11,11,12,13,14,14,15,15,16,16,16,17,18,18,19,20,21,22,23,24

we have a total of 20 numbers/observation, to get the median value, we will have to get the average of the middle number. in this case, the 10th and 11th number is 16,16 so the average of the is 16. Therefore, our median value is 16
