Parametric Test VAL

Parametric tests make assumptions about the data, such as the observations being normally distributed. This can be verified with a test of normality prior to executing a parametric test.

Options

Allow Duplicates

Specifies whether duplicates are allowed in the output or not.

Columns

Specifies the name(s) of the column(s) representing independent variables to be analyzed in a F-Test N-Way with Equal Cell Counts analysis.

Dependent Column

Specifies the name of the column representing the dependent variable in an F-Test.

Equal Variance

Specifies whether the variance of the two samples (columns) is assumed to be equal.

Fallback

Specifies whether the FALLBACK is requested as in the output result or not.

First Column Values

Required for a 2-way F-Test with Unequal Cell Counts. Specifies a list of the 'first_column' values to be included in the analysis. E.g. type each number as seperate entries for example 1, 2, 3, 4.

First Column

Specifies the name of the column representing the first variable to analyze for a T-test. For an F-Test, specifies the name of the column representing the first independent variable in the analysis.

Group Columns

Specifies the name(s) of the column(s) for grouping so that a separate result is produced for each value or combination of values in the specified column or columns.

Paired

Specifies whether the first and second column values are matched with each other.

Probability Threshold

Specifies the threshold probability, i.e., 'alpha' probability, below which the null hypothesis is rejected.

Second Column Values

Required for a 2-way F-Test with Unequal Cell Counts. Specifies a list of the 'second_column' values to be included in the analysis. E.g. type each number as seperate entries for example 1, 2, 3, 4.

Second Column

Specifies the name of the column representing the second variable to analyze.

Style

Specifies the test style.

Second Column Indicates Analysis Categories

Specifies whether the second column is used to indicate there are two analysis categories
