To access the statistical functions, make sure you are in Statistics mode; the title bar should end with [stats]. If not, click mode and select Statistics from the Number/Mode group. In statistics mode, the bottom right-hand button on the calculator is data. To input values for analysis, enter numbers and click data after each number is input. Repeat this process until you have entered all the data values. If you press the shift button on the calculator, some of the number keys change to the statistics functions:
For example, to get the number of points entered, press n ; to get the mean of the data, press the button labeled mean. Similarly ssd (or sdv) is the standard deviation, etc.
To clear the statistics memory, press shift and then press SAC (Statistics All Clear) button (which was labeled AC before pressing shift).
To input values for analysis, enter numbers and click data after each number is input. Repeat this process until you have entered all the data values.
To clear the statistics memory, press the shift button, followed by SAC (i.e. shifted AC).
Computes the number of permutations nPr.
Example:
To compute the number of ways of arranging five objects chosen from
a population of ten:
1 0 shift nPr 5 =
Result: 30240
Note: The calculator must be in statistics mode.
Computes the number of combinations nCr.
Example:
To compute the number of combinations of five objects chosen from a
population of ten (without regard to the order of choosing):
1 0 shift nCr 5 =
Result: 252
Note: The calculator must be in statistics mode.
To obtain the maximum of all the values entered into the statistics memory, press shift then max.
To obtain the minimum of all the values entered into the statistics memory, press shift then min.
To obtain the total number of values entered into statistics memory, press shift then n.
To obtain the sum of all the values entered into statistics memory, press shift then sum.
To obtain the sum of the squares of all the values entered into statistics memory, press shift then ssq.
To obtain the mean (arithmetic average) of all the values entered into statistics memory, press shift then mean.
To obtain the standard deviation of all the values entered into statistics memory, press shift then sdv.
To obtain the sample standard deviation of all the values entered into statistics memory, press shift then ssd.
