How do you find a marginal frequency?
The marginal relative frequencies are found by adding the joint relative frequencies in each row and column. To find a conditional relative frequency , divide the joint relative frequency by the marginal relative frequency.

How do you find the marginal distribution in statistics?
g(x) = Σy f (x,y) and h(y) = Σx f (x,y) are the marginal distributions of X and Y , respectively (Σ = summation notation). If you're great with equations, that's probably all you need to know. It tells you how to find a marginal distribution.
How do you explain marginal distribution?
In probability theory and statistics, the marginal distribution of a subset of a collection of random variables is the probability distribution of the variables contained in the subset. It gives the probabilities of various values of the variables in the subset without reference to the values of the other variables.
What is marginal in statistics?
A marginal distribution is a distribution of values for one variable that ignores a more extensive set of related variables in a dataset.

This group allows you to request model-predicted estimated marginal means of the dependent variable in the cells and their standard errors for the specified factors. Moreover, you can request that factor levels of main effects be compared.
