To define statistical data points:
1. Enter data in L1, L2, or L3. (See Data editor.)
Note: Non-integer frequency elements are valid. This is
useful when entering frequencies expressed as
percentages or parts that add up to 1. However, the
sample standard deviation, Sx, is undefined for non-integer
frequencies, and Sx = Error is displayed for that value. All
other statistics are displayed.
2. Press % u. Select 1-Var or 2-Var and press
