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.
Given list data in a list variable (LI, for example), store LI
into a data column variable (Cl, for example), and then
compute its statistics.
1. In Home, store LI into Cl. You will be able to see the list
data in the Numeric view of the Statistics aplet.
2. In the Numeric view of the Statistics aplet, set IVAR mode
(press {{2VAR
b
}}, if necessary, to display {{IVARn}}).
3. In the Symbolic view, define HI (for example) as Cl
(sample) and 1 (frequency). Make sure that HI is
checkmarked.
4. In the Numeric view, press {{
stats
}}.
NS is the number of elements in LI.
TOTS is the sum of all elements in LI.
MEANS is the mean value of all elements in LI.
MINS is the smallest element in LI.
MEDIAN is the median value of all elements in LI.
MAXS is the largest element in LI.
