Finding statistical values for list elements
To find values such as the mean, median, maximum, and
minimum values of the elements in a list, use the Statistics
aplet.
Example

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.
