Suppose you want to calculate statistical measures on the following sorted data:

4, 4, 5, 5, 5, 6, 6, 6, 6, 6, 7, 7, 8, 8, 8, 8, 8, 8, 9, 9

1. Create a new document and select Add List & Spreadsheet, then enter each value in the chosen list (here: A):

   

2. Press , select Statistics > Stat Calculations > One-Variable Statistics, and select the parameters as follows:

   

3. Press . These results are displayed:

   

Here is the table of notations:

• x̄: mean
• n: size of the sample
• Σx: sum of all values
• Σx²: sum of all squares of values
• Sx: standard deviation of the sample
• σx: estimation of the population's standard deviation
• MinX: minimal value
• Q1X: lower quartile
• MedianX: median
• Q3X: upper quartile
• MaxX: maximal value

Consider the following data:

Values	Frequency
4	2
5	3
6	5
7	2
8	6
9	2

1. Create a new document and select Add List & Spreadsheet. Enter the values in one list (here: A) and the frequency list in a second list (here: B).

   

2. Press , select Statistics > Stat Calculations > One-Variable Statistics, and fill the parameters as follows:

   

3. Press . These results are displayed:
