Statistical Calculations

This calculator has two statistical calculation functions of One-Variable Statistics Mode (STAT1) and Two-Variable Statistics Mode (STAT2). In the statistics modes, there are some restrictions.

• 1. The results of statistical calculations are stored into the memory. When you start new statistical calculations, press the [INV]AC key to clear all the stored data.

  2. The calculation levels are up to 3 levels. More than 3 is an overflow error.

  3. Two-Variable function keys (coordinate conversions, permutations, and combinations) cannot be used in the statistics modes. In the two-variable statistics mode, the storage memories (S7 — S9) can not be used. The calculations below can be performed.

     1. • Arithmetical calculations

        • Power and power universal calculations

        • Calculations of independent memories

        • Percentage calculations

        • One-variable calculations

        • Parenthesis calculations

        • Constant calculations

  4. Results of variable calculations can be entered. Press the [=] key or the [)] key to finish the calculation, before you result as a variable.

  5. The input limit of variables and data.
