median = 4

step-by-step explanation:

we are given a histogram which shows a data distribution. given that all class widths are 1, we are to find the median of this data distribution.

in any data set or distribution, median is its middle value such that the data is sorted out in an ascending order.

so here, we have 7 values and the middle value will be 4 as it separates the higher half from the lower half of the date distribution.

median = = 4
