The number of degrees of freedom for a test of independence is equal to the sample size minus one.

Short Answer

Expert verified

The statement is false.

Step by step solution

Concept Introduction

The Chi-square test of independence is a statistical hypothesis test used to determine whether two categorical or nominal variables are likely to be related or not.

Explanation

If we are given the table with $n$ row and $m$ columns, the number of degrees of freedom is calculated as

$(n - 1) (m - 1)$

Thus, the statement is false.
