The Statistics 1Var symbolic variables are H1 to H5. These variables contain the data values for a one-variable
statistical analysis. For example, H1(n) returns the nth value in the data set for the H1 analysis. With no
argument, H1 returns a list of the objects that dene H1. These objects are as follows, in the order given:
●
An expression (in single quotes) that denes the data list (or empty double quotes)
●
An expression (in single quotes) that optionally denes the frequencies for each of the values in the data
list (or empty double quotes)
●
The plot type number
●
The option number
●
The color for the plot
The plot type number is an integer from 1 to 9 that controls which statistical plot type is used with each of the
variables H1 to H5. The correspondence is as follows:
●
1—Histogram (default)
●
2—Box and whisker
●
3—Normal probability
●
4—Line
●
5—Bar
●
6—Pareto
●
7—Control
●
8—Dot
●
9—Stem and leaf
The option number is an integer from 0 to 2 that controls any option available for the plot type. The
correspondence is as follows:
●
0—No option
●
1—Do not show outliers for the box-and-whisker plot
●
2—Show outliers for the box-and-whisker plot
Example:
H3:={"D1", "", 2, 1, #FF:24h} denes H3 to use D1 for its data list, use no frequencies, and draw
a box-and-whisker plot without outliers in blue.
Method
Inference
Determines whether the Inference app is set to calculate hypothesis test results or condence intervals. In
Symbolic view, make a selection for Method.
In a program, type:
0 ▶ Method—for Hypothesis Test
2 ▶ Method—for Condence Interval
3 ▶ Method—for Chi-Square
4 ▶ Method—for Regression
Program commands 621
