CHITEST function

PRO

The CHITEST function in Jspreadsheet Formulas Pro is a statistical tool that compares the actual and anticipated frequencies of certain categories within a data table. This is to see if there's a notable correlation between different variables. In simpler terms, it helps you check if what you predicted in your data matches up with what actually happened. It's a useful function for analyzing and making conclusions about your data.

Documentation

Compares the observed and expected frequencies of categories in a contingency table to determine whether there is a significant association between the variables.

Syntax

CHITEST(actual_range, expected_range)

Parameter	Description
`actual_range`	A range of cells containing the observed frequency counts. Each cell must contain a non-negative number.
`expected_range`	A range of cells containing the expected frequency counts. Each cell must contain a non-negative number.

Behavior

The CHITEST function is used to perform a chi-square test on data. It compares an observed set of values with an expected set to determine if there's a significant difference between them. The function returns a probability from the chi-square distribution.

If the input arrays are of different sizes, CHITEST returns a #N/A! error.
CHITEST ignores cells with non-numeric values.
If a cell in either array is empty or contains text, CHITEST will treat it as a zero.
If a cell in either array contains a boolean value, CHITEST will treat TRUE as 1 and FALSE as 0.
If any value in the expected array is less than or equal to zero, CHITEST will return a #NUM! error.

Common Errors

Error	Description
#NUM!	This error occurs when any value in the expected array is less than or equal to zero.
#VALUE!	Occurs when cells contain non-numeric values
#N/A	Returned when input arrays have mismatched dimensions.

Best practices

Ensure that your observed and expected arrays are of the same size. Mismatched sizes can result in errors or inaccurate results.

Avoid including non-numeric values in your data ranges as they can distort your test results.

Make sure no value in the expected array is less than or equal to zero, as this will cause the function to return an error.

It's a good practice to check your output. If the p-value (the result of the CHITEST) is less than the significance level (often 0.05), you can reject the null hypothesis.

Usage

A few examples using the CHITEST function.

CHITEST(A2:B4, C2:D4)  → 0.0812  // Indicates no statistically significant difference
