This algorithm can easily be adapted to compute the variance of a finite population: simply divide by n instead of n − 1 on the last line.. Because SumSq and (Sum×Sum)/n can be very similar numbers, cancellation can lead to the precision of the result to be much less than the inherent precision of the floating-point arithmetic used to perform the computation.
TI-BASIC 83 (on Z80 processor) for TI-83 series, TI-84 Plus series; TI-BASIC 89 (on 68k processor) for TI-89 series, TI-92 series, Voyage 200; TI-BASIC Nspire (on ARM processor) for TI-Nspire and TI-Nspire CAS; TI rarely refers to the language by name, but the name TI-BASIC has been used in some developer documentation.

Many of the calculators in this list have region-specific models that are not individually listed here, such as the TI-84 Plus CE-T, a TI-84 Plus CE designed for non-French European markets.
Squared deviations from the mean (SDM) result from squaring deviations.In probability theory and statistics, the definition of variance is either the expected value of the SDM (when considering a theoretical distribution) or its average value (for actual experimental data).
Here is a brief overview of what Xcas is able to do: [9] [10] Xcas has the ability of a scientific calculator that provides show input and writes pretty print; Xcas also works as a spreadsheet; [11]
TI-84 Plus CE Menu example. The image is how the calculator renders the example above. In terms of functionality, the Menu('s flow is similar to some switch statement and cases, with a key difference that the user supplies the switch's usual expression. Like many switches and cases, the Lbl allows fall-through. For example, in the code above ...
