ShotStat was created to provide shooters with a statistics package to help evaluate hand load performance. The idea was to develop a program that allowed shooters to enter data graphically to reduce both time required and technical measurement and calculation for evaluating shot groups.
So, what does ShotStat actually do? The program is basically a statistics calculator for any data set up to 20 elements. You can use this to calculate statistics for shot groups, load velocities, maximum (peak) pressures, case masses, bullet masses, bullet diameters, case expansion, etc. It is up to your imagination the data sets that can be used.
That said, ShotStat is primarily designed to evaluate load performance. With this version, two additional tools have been added: T-test and F-test. The T-test tool is used for deciding if the difference between two averages (such as impact point, velocity, etc.) is statistically significant. The F-test is similarly used to determine if the difference between two variances (such as group size or velocity spread) is statistically significant. These tools extend ShotStat's utility for both load evaluation and firearms training.
