What is the difference between Type A and Type B uncertainty?

Type A uncertainty is calculated from the statistical analysis of a series of observations, while Type B uncertainty is based on non-statistical information such as manufacturer specifications or calibration data.

How do I calculate the total uncertainty from multiple sources?

You can use the `calculate_combined_uncertainty` tool. It takes a list of individual standard uncertainties and applies the root sum of squares method to find the total combined uncertainty.

What coverage factor should I use for a 95% confidence interval?

A coverage factor of 2 is commonly used to provide approximately 95% confidence when using the `calculate_expanded_uncertainty` tool.

This MCP server provides specialized tools for calculating measurement uncertainty in analytical results. It handles both Type A uncertainty, derived from statistical analysis of repeated measurements, and Type B uncertainty, derived from external information like calibration certificates. Users can use evaluate_type_a_uncertainty to process observation sets, evaluate_type_b_uncertainty for distribution-based estimates, and calculate_combined_uncertainty to aggregate all sources using the root sum of squares method. Finally, calculate_expanded_uncertainty allows for the determination of confidence intervals using specific coverage factors.
