We can use Venn diagrams and two-way tables. Venn diagrams show sets and their overlaps. Two-way tables organize data in rows and columns. Both methods help show relationships between categories. video https://cdn.kastatic.org/googleusercontent/5-nYxcy8oey3CjUjKCQsbWWgSxm4wzvRQEWmBcgx9YhWV-MZDGKj81xcWxfZxlaTUpxWWGnBl2Zzl1OtW4mgXcA2lA Two-way frequency tables and Venn diagrams Sometimes data belongs to more than one category. For example, candies might have chocolate, coconut, both, or neither.

In our example, we calculate the relative frequency of accidents for SUVs by dividing the number of SUVs that had accidents by the total number of SUVs. This gives us a percentage or fraction that tells us how common accidents are for that type of vehicle. video https://cdn.kastatic.org/googleusercontent/kp96ixiOEk1kZueqSJEmIfQNQ2CtNaT6SN_wU9clMbIOs663z9TWkW6QExTVKiBKHszd2vvJ2Ycl4ZqbUje0VMA Two-way relative frequency tables Relative frequencies show how often something happens compared to the total number of times it could happen.
