To find values such as the mean, median, maximum, and
minimum values of the elements in a list, use the Statistics
aplet.
In this example, use the Statistics aplet to find the mean,
median, maximum, and minimum values of the elements
in the list, L1.
1. Create L1 with values 88, 90, 89, 65, 70, and 89.
{ 88 90
89 65 70 89
}
L1
2. In HOME, store L1 into
C1. You will then be
able to see the list data in the Numeric view of the
Statistics aplet.
