Worked Out Examples
In the following examples, we list the exact key sequence used to find the answer. We will list the keys by the main symbol on the key. In parentheses, we will list a helpful mnemonic, e.g. we will list ex as (ex).
A: What is the mean and standard deviation of the following list of numbers?
15 16 20 21
1: Clear Memory | |
2: Enter Data | |
3: Compute the mean | (x) |
4: Compute the population standard deviation | (sn) |
5: Compute the sample standard deviation | (sn-1) |
You should get a mean of 18, population standard deviation of
2.549509757 and a sample standard deviation
of 2.943920289.
C: Find 10C6 and 9P5.
1:Compute 10C6 |
|
2: Compute 9P5 |
You should get 10C6 = 210 and 9P5=
15120.
