Marginal frequency of a category is given by the sum of elements in the row/column corresponding to that category.
The following is two-way table with marginal frequency
\(\begin{array}{|c|c|}\hline & \text{Fiction} \\ \hline & \text{Likes} & \text{Dislikes} \\ \hline \text{Non Fiction} \\ \hline \text{Likes} & 26 & 22 \\ \hline \text{Dislikes} & 20 & 2 \\ \hline \end{array}\)
We observe that: a. 46 students liked fiction whereas 24 disliked fiction.
b. 48 liked non-fiction whereas 22 disliked non-fiction.
