Discussion:
Q: Comparing the accuracy and reproducibility of 3 different force gauges with varied angles and applied pressures. All of the gauges have a 50 lb. capacity. They will all be tested with 0-30 lbs in 5 lb increments of applied load/pressure. They will also be tested at 0 degrees (true perpendicular) and at 5 degree increments up to 30 degrees with the varied loads applied. I need to know what statistical formulas I should use, the most appropriate charts, tables, spreadsheets, etc. and the best layout for my data
