Put these values into the equation to calculate zobs. WebTo make the SPSS results match those from other packages, you need to create a new variable that has the opposite coding (i.e., switching the zeros and ones). The result of the procedure looks like this. The following procedure selects the part of the dependent data that matches the equation. Some people would prefer a bar chart since these are independent groups and a line suggests they are related. matches the equation.
