She is looking at the attendance of the students as it is. 0 The coefficients in the equation define the relationship between each independent variable and the dependent variable. X2 represents the test statistic (chi-square). One approach would be to perform a series of t-tests or ANOVAs to test for differences among the species, but this would be tedious, especially if there are many variables. Step 3: Verify that the model fits the data well. What would be the problem with conducting a true experiment regarding smoking during pregnancy?
