Chapter 4 Statistics - Casio fx9750GII Getting Started

STATISTICS
The statistics icon incorporates the two types:
• Univariate (1 variable)
• Multivariate (2 variables).
There are 24 'list' spaces that you can enter data into. Lists 1 to 24 can be used in any order. The lists can be used as
frequency values also. Note that you can only see 4 lists at a time.
The distinction between the lists and what you propose to do with them is determined by the way you set up the
calculation or graph types required and the lists you are using to calculate the numerical statistics and drawing statistical
graphs.
Three independent graphs can be set up as univariate or multivariate data from different or from the same lists.
[F1] [F6] to SET up the statistical graph types.
Graphing options are:
F1 Scatter Graph
F2 Line Regression
F3
Time Series
F4

F1
Linear Regression
F2
Median/Median
Regression
F3 Quadratic Regression
F4 Cubic Regression
F5
Quartic Regression
Data Entry
You can enter up to 999 data points in each 'list' space.
Note: Memory space is approximately 64000 (64k) bytes and using large data sets can utilise a lot of memory space.
Uni-variate
Example
In 'List 1' enter the following data. Find all of the central measures values. Draw the Box and Whisker,
Histogram and Normal Distribution approximation for this data.
