## Degrees of Freedom in One-way ANOVA Test within Groups Solution

STEP 0: Pre-Calculation Summary
Formula Used
Degrees of Freedom = Total Sample Size-Number of Groups
DF = NTotal-NGroups
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.
Total Sample Size - Total Sample Size is the combined number of individuals in both Sample X and Sample Y. It represents the overall size of entire sample when combining data from different sources or groups.
Number of Groups - Number of Groups is the count of distinct categories, classes, or levels in a dataset. It represents the different divisions used to classify or group data points for analysis.
STEP 1: Convert Input(s) to Base Unit
Total Sample Size: 17 --> No Conversion Required
Number of Groups: 9 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
DF = NTotal-NGroups --> 17-9
Evaluating ... ...
DF = 8
STEP 3: Convert Result to Output's Unit
8 --> No Conversion Required
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.
