A box plot is a graph that sows the distribution of 1 dimension data
To begin we organize the data in order
23,25,25,26,28,33,34,39,40,43,44,45,45,46,46
So we get the median which is the value in the middle position in this case 39
Then the first quartile: 26 and the third quartile: 45.
Finally, the minimum is 23 and the maximum is 46
Let's see one example of the graph
So we make our graph using the values that just found
And that is our answer
