This tool helps you calculate the probability of bias in your data sets.
How to Use the Bias Calculator
To use the bias calculator, fill in the input fields with the required values for both Group 1 and Group 2:
- Mean of Group 1 and Group 2: The average value of each group.
- Standard Deviation of Group 1 and Group 2: The measure of variation or dispersion of each group.
- Sample Size of Group 1 and Group 2: The number of observations in each group.
Click the “Calculate” button to get the bias result. The result is displayed in the “Result” field.
How the Calculator Works
The bias is calculated using the formula:
(Mean of Group 1 - Mean of Group 2) / Pooled Standard Deviation
The pooled standard deviation is calculated as:
sqrt[((std_dev1^2 * (size1 - 1)) + (std_dev2^2 * (size2 - 1))) / (size1 + size2 - 2)]
Limitations
This calculator assumes both groups have the same variance and a normal distribution of data. It may not be accurate for data that does not meet these assumptions.
