Launch Uncertainty Calculator using Java Webstart.
The Uncertainty Calculator lets you make calculations involving numbers that are not precisely known. As all measurements have uncertainty, you can make better decisions based on your measurements if you include uncertainties in your calculations.
The Uncertainty calculator is a Java application. It is best run from Java Webstart. You need to have java installed on your computer. Click here to install Java). Then click on the link below to download and run the application.
Each value x has an associated uncertainty, dx. A Gaussian distribution of values is created that reflects this value. All calculations in the uncertainty calculator are then done as calculations involving distributions. For example, multiplying two distributions together results in a new distribution. The uncertainty calculator keeps this distribution internally but displays its mean and standard deviation to you as the result of the calculation.
This technique effectively copes with nonlinear functions. In the future you'll be able to visualise the distribution as a probability density function.
The uncertainty calculator was written by Timothy Christopher Anthony Molteno!
