perl · Answer

The median separates the lower 50% of the data from the upper 50% of the data. Because the histogram is symmetric, that means the median will be geometrically in the center of the histogram.

so 40,000

perl · Answer

the middle point is in between 20,000 and 30,000

perl · Answer

the mean is the average , so you add them all up and divide by the number of values

perl · Answer

$\Large  mean = \frac{1+ 1+ 2+2+ 2+ 3+ 3+ 3+ 3+ 4+ 4+ 4+ 5+ 5+ 6+ 7}{16}$

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?

perl · Answer

the median is the 'center' value. first order the values from least to greatest:
$$ \large  {1, 1, 2, 2, 2, 3,3, 3,\color{red}{median~ is ~here~} 3,  4, 4, 4, 5, 5, 6, 7}$$
