Degrees of Freedom in Simple Linear Regression Test Solution

STEP 0: Pre-Calculation Summary
Formula Used
Degrees of Freedom = Sample Size-2
DF = N-2
This formula uses 2 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.
Sample Size - Sample Size is the total number of observations or data points collected in a sample. It represents the number of individuals, items, or events included in the sample.
STEP 1: Convert Input(s) to Base Unit
Sample Size: 10 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
DF = N-2 --> 10-2
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.
