Accumulating Statistics

The HP-10C can perform one- or two-variable statistical calculations. The data
are entered into the calculator using the z key, which automatically
calculates and stores statistics of the data in storage registers R
(These registers are therefore referred to as the statistics registers.)
Before beginning to accumulate statistics for a new set of data, you should clear
the statistics registers by pressing ´CLEARQ.
In one-variable statistical calculations, to enter each data point—referred to as
an x-value—key the x-value into the display, then press z.
In two-variable statistical calculations, to enter each data pair—referred to as
the x- and y-values;
1. Key the y-value into the display first.
2. Press v.
3. Key the x-value into the display.
4. Press z.
