18-3 Calculating and Graphing Single-Variable
Statistical Data
Single-variable data is data with only a single variable. If you are calculating the
average height of the members of a class for example, there is only one variable
(height).
Single-variable statistics include distribution and sum. The following types of
graphs are available for single-variable statistics.
k k k k k Drawing a Histogram (Bar Graph)
From the statistical data list, press 1 (GRPH) to display the graph menu, press
6 (SET), and then change the graph type of the graph you want to use (GPH1,
GPH2, GPH3) to histogram (bar graph).
P.251
Data should already be input in the statistical data list (see "Inputting Data into
P.252
Lists"). Draw the graph using the procedure described under "Changing Graph
Parameters".
P.254
(Graph Type)
(Hist)
The display screen appears as shown above before the graph is drawn. At this
point, you can change the Start and pitch values.
k k k k k Med-box Graph (Med-Box)
P.254 This type of graph lets you see how a large number of data items are grouped
(Graph Type) within specific ranges. A box encloses all the data in an area from the 25th
(Box) percentile to the 75th percentile, with a line drawn at the 50th percentile. Lines
(called whiskers) extend from either end of the box up to the minimum and
maximum of the data.
From the statistical data list, press 1 (GRPH) to display the graph menu, press
6 (SET), and then change the graph type of the graph you want to use (GPH1,
GPH2, GPH3) to med-box graph.
