Two Way Tables/Venn diagrams

Front

What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of two categorical variables, allowing for the comparison of the relationship between them.

Front

What is a Venn diagram?

Back

A Venn diagram is a visual representation that shows all possible logical relations between a finite collection of different sets, often using overlapping circles.

Front

How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the frequency of a specific category by the total number of observations.

Front

What does it mean if two events are independent?

Back

Two events are independent if the occurrence of one event does not affect the probability of the other event occurring.

Front

What is the purpose of using a two-way table?

Back

The purpose of using a two-way table is to summarize and analyze the relationship between two categorical variables.

Front

How can you find the total number of surveyed individuals from a two-way table?

Back

You can find the total number of surveyed individuals by summing all the frequencies in the table.

Front

What is the formula for calculating the percentage of a category in a two-way table?

Back

The percentage of a category is calculated by dividing the frequency of that category by the total frequency and then multiplying by 100.

Front

What does it mean if two sets in a Venn diagram do not overlap?

Back

If two sets in a Venn diagram do not overlap, it means that they are mutually exclusive, and there are no common elements between them.

Front

How do you interpret the data in a two-way table?

Back

To interpret data in a two-way table, analyze the frequencies and relative frequencies to understand the relationship between the two variables.

Front

What is a joint frequency in a two-way table?

Back

Joint frequency refers to the count of occurrences for a specific combination of two categories in a two-way table.
