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 = (N_Rows-1)*(N_Columns-1)
This formula uses 3 Variables

Variables Used

Degrees of Freedom - Degrees of Freedom is the number of values in the final calculation of a statistic that are free to vary. It varies based on the specific statistical test or analysis being conducted.
Number of Rows - Number of Rows is the count of horizontal divisions in a table or dataset. Each row typically represents a single observation, individual, or case in the dataset.
Number of Columns - Number of Columns is the count of vertical divisions in a table or dataset. In statistical analysis, it often refers to the number of variables or attributes being measured for each observation.

STEP 1: Convert Input(s) to Base Unit

Number of Rows: 5 --> No Conversion Required
Number of Columns: 3 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

DF = (N_Rows-1)*(N_Columns-1) --> (5-1)*(3-1)

Evaluating ... ...

DF = 8

STEP 3: Convert Result to Output's Unit

8 --> No Conversion Required

FINAL ANSWER

8 <-- 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.

How to Calculate Degrees of Freedom in Chi-square Independence Test?

Degrees of Freedom in Chi-square Independence Test calculator uses Degrees of Freedom = (Number of Rows-1)*(Number of Columns-1) to calculate the Degrees of Freedom, Degrees of Freedom in Chi-square Independence Test formula is defined as the number of values in the final calculation of a statistic that are free to vary. It varies based on the specific statistical test or analysis being conducted in the chi-square independence test of given data sample. Degrees of Freedom is denoted by DF symbol.
