its basically a box and whisker plot with a minimum , maximum etc

Answer 3

yeah, why they didnt say box and whisker ....

first sort the numbers; thatll tell you min and max, and give us a way to pull the rest

Answer 4

there are 10 numbers, so the median is in the middle of the 2 center values

Answer 5

finding quartiles is just dividing the number of elements by 4 to determine the positional place of q

10/4 = 2.5;

Q1 = 1(2.5) rnded up
Q2 = 2(2.5) is a hole number so average is required
Q3 = 3(2.5) rnded up
