An histogram is a bar-like graph used to represent numerical data. On the y-axis is the frequency of the data and on the x-axis is the data

median is a measure of central tendency. It measures the middle number in a set of observation

there are 20 observations (visitors),

1, 2, 3,5,6, 7, 8, 9,| 10, 11, | 12,13,14,15,16,17,18,19,20

the median is 10 and 11 or 10.50

there are 9 numbers on either sides of 10 and 11

the 10th and 11th visitor would be found in the age group 20 - 29
