θ0o 1.047197551

•0 n, 0 o swaps displayed value with value in memory.

kPermutation

•Example: To determine how many different 4-digit val- ues can be produced using the numbers 1 through 7

•Numbers cannot be duplicated within the same 4-digit value (1234 is allowed, but 1123 is not).

7 Am 4 = 840.

kCombination

•Example: To determine how many different 4-member groups can be organized in a group of 10 individuals

10 An 4 = 210.

Statistical Calculations

kStandard Deviation (SD Mode)

•Press F F 1 to enter the SD Mode for statistical calculations using standard deviation.

•Data input always starts with Am=to clear statisti- cal memory.

• Input data is used to calculate values for
