Homogeneity test calculator
WebThe marginal homogeneity test / stuart-maxwell test could for instance be used to answer the question: Subjects are asked to taste three different types of mayonnaise, and to indicate which of the three types of mayonnaise they like best. They then have to drink a glass of beer, and taste and rate the three types of mayonnaise again. WebA differential equation f(x,y) is said to be homogeneous if f(x,y) = g(y/x). This GeoGebra applet solves shows how to solve a homogeneous DE. It also provides visualization of …

Otherwise, you can calculate by hand (or use our variance and standard deviation calculator). For this example, our variances are 12 and 4. Step 2: Divide the larger variance by the smaller variance to find the F max ratio:
