A two-way table is a frequency table that displays data collected from one source that belongs to two different categories. One category of data is represented by rows and the other is represented by columns. The sums of the rows and columns are called marginal frequencies. Let's calculate these sums to find the missing marginal frequencies. Likes Fiction:& 26+ 20= 46 Dislikes Fiction:& 22+ 2= 24 Likes Non Fiction:& 26+ 22=48 Dislikes Non Fiction:& 20+ 2=22 In the marginal frequencies, we can see that 46 students liked fiction whereas 24 students disliked. Moreover, there are 48 students liked nonfiction whereas 22 disliked nonfiction. A total of 70 students were surveyed.
