All the other boxes should have the value zero (’0’). Input an expected integer number in the top box and an observed number in the second box. To test for the significance of a difference between one observed Poisson count and an expected count. Select options and hit the calculate button.Ĭompare a single sample with the population For three or more averages use the oneway procedure. Input two observed real numbers in the top two boxes, two numbers of cases in the number of cases boxes and two standard deviations in the standard deviations boxes, so that there is a value in each box. To test for the significance of a difference between two normally distributed averages. For three or more percentages use the 2xr procedure. If you input a number it will be divided by the number of cases before the analysis to obtain a proportion. Input two observed proportions or two observed integer numbers in the top two boxes and two numbers of cases in the number of cases boxes. To test for the significance of a difference between two proportions or percentages. Input two observed counts in the top two boxes. To test for the significance of a difference between two Poisson counts.
