Introduction: The Critical Value Table Calculator is a valuable tool in statistical analysis, allowing researchers and students to determine the critical value from a standard statistical table. This online calculator simplifies the process, making it easy to find the critical value based on degrees of freedom and a chosen confidence level.
Formula: The critical value is obtained by subtracting the confidence level (expressed as a percentage) from 100 and converting it to a decimal.
How to Use:
- Input the degrees of freedom in the designated field.
- Enter the desired confidence level as a percentage.
- Click the “Calculate” button to obtain the critical value from the table.
Example: Suppose you have 10 degrees of freedom and want a 95% confidence level. Input these values, click “Calculate,” and the result will be displayed.
