## Degrees of Freedom in Chi-square Independence Test Solution

STEP 0: Pre-Calculation Summary
Formula Used
Degrees of Freedom = (Number of Rows-1)*(Number of Columns-1)
df = (NRows-1)*(NColumns-1)
This formula uses 3 Variables
Variables Used
Degrees of Freedom - Degrees of Freedom is the maximum number of logically independent values which are values that have the freedom to vary in the data sample.
Number of Rows - Number of Rows is the total count of the rows in the contingency table of a grouped data for chi square test.
Number of Columns - Number of Columns is the total count of the columns in the contingency table of a grouped data for chi square test.
STEP 1: Convert Input(s) to Base Unit
Number of Rows: 9 --> No Conversion Required
Number of Columns: 8 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
df = (NRows-1)*(NColumns-1) --> (9-1)*(8-1)
Evaluating ... ...
df = 56
STEP 3: Convert Result to Output's Unit
56 --> No Conversion Required
56 <-- Degrees of Freedom

## What is Degree of Freedom in Statistics?

In inferential statistics, we estimate a parameter of a population by calculating a statistic of a sample. The number of independent pieces of information used to calculate the statistic is called the degrees of freedom. The degrees of freedom of a statistic depend on the sample size. When the sample size is small, there are only a few independent pieces of information, and therefore only a few degrees of freedom. When the sample size is large, there are many independent pieces of information, and therefore many degrees of freedom.
Although degrees of freedom are closely related to sample size, they’re not the same thing. There are always fewer degrees of freedom than the sample size.
When we estimate a parameter, we need to introduce restrictions in how values are related to each other. As a result, the pieces of information are not all independent. To put it another way, the values in the sample are not all free to vary.
