Press Cwhen you have completed the data entry stage. Don‛t panic when the scores disappear. The process for finding the mean and standard deviation is the same as outlined in the example using scores without frequencies. In the scores with frequencies example the mean is 5.1 and the standard deviation is 1.03.

The random number function

The calculator has two random number features. Ran# generates 3-digit pseudo random numbers between 0 and 1. RanInt generates random integers in a specified domain.

Using Ran#

If you want the number to be displayed as a decimal set the calculator to work in LineIO. In MathIO the random numbers are displayed as fractions. Press q.p and a random decimal will be displayed. Each time you press panother random number will be displayed.

Random number formulas

Random numbers can be incorporated into calculations.

For example, the formula 1 + 2 × Ran# will generate random numbers between 1 and 3. Each press of pwill generate another random value between 1 and 3.

The RanInt function

To simulate the result of rolling a normal 6-sided die the formula RanInt#(1,6) is required. Enter this formula as Q.1q)6)p. Each time you press panother die simulation will be displayed.

The formula RanInt#(1,6) + RanInt#(1,6) simulates the results of rolling a pair of dice and adding the numbers showing.
