Students observe how errors combine, attempt to optimize precision and accuracy of the measurement.
Return to the Index. The group of variables in the top left of the screen are independent variables that you can change. The group of variables in the bottom left of the screen are dependent variables that are automatically calculated from the independent variables. This simulates the 20 spearate standard addition experiments with random errors caused by Es and Ev. The results are shown in the table on the right of the screen.
