Non-integer freq elements are valid. This is useful when
entering frequencies expressed as percentages or parts that
add up to 1. However, if freq contains non-integer frequencies,
Sx and Sy (sample standard deviation) are undefined, and
values are not displayed for Sx and Sy in the statistical results.

1-Var Stats (one-variable statistics) analyzes data from one list
with one measured variable (X). 1-Var Stats accepts two
optional arguments, XList and freq. If XList is not specified,
the default list name is L1.
1-Var Stats [XList,freq]
2-Var Stats (two-variable statistics) analyzes paired data from
two lists with two measured variables, X, the independent
variable, and Y, the dependent variable. 2-Var Stats accepts
three optional arguments, XList, YList, and freq. If XList and
YList are not specified, the default list names are L1 and L2.
2-Var Stats [XList,YList,freq]
Find the 1-Var Stats for L1, where L1={1,3,4,5,5,7,8,9}. Use L2 as
freq, where L2={1,4,2,3,4,6,7,9}.
1. Define two lists in the List
editor, L1 and L2.
