Check

Check lets you compare the values of a specific column against the rest of the dataset or a subset of columns to see whether that column's values follow a normal distribution.

Format

Check uses two utterances:

• Check the normality of the column <column>
• Check the normality of the column <column> for each <comparison columns>

Parameters

Check uses the following parameters:

• column (required). The column whose normality to check. Note that columns with date or time values cannot be selected.
• comparison columns (optional).

Output

When Check finishes, a table is shown in the display panel that lists each of the comparison columns and whether the values of the specified column follow a normal distribution when compared against each of those columns. A success message also appears in the chat history.

Otherwise, an error message appears in the chat history.

Examples

To check the normality of the numeric column "Fare" against the numeric column "Age" and the string column "Gender," enter Check the normality of the column Fare for each Age, Gender.
