Two-Way Tables

Front

What is a two-way table?

Back

A two-way table is a statistical table that displays the frequency distribution of variables. It allows for the comparison of two categorical variables.

Front

How do you calculate the percentage from a two-way table?

Back

To calculate the percentage, divide the frequency of the specific category by the total frequency and multiply by 100.

Front

What does it mean if a two-way table shows a high percentage in a specific category?

Back

A high percentage indicates that a large proportion of the total observations fall into that category, suggesting a strong association between the variables.

Front

What is the purpose of using two-way tables in statistics?

Back

Two-way tables are used to summarize data, analyze relationships between two categorical variables, and facilitate the calculation of probabilities.

Front

How can you find the probability of an event using a two-way table?

Back

The probability of an event can be found by dividing the frequency of the event by the total number of observations.

Front

What is a marginal total in a two-way table?

Back

A marginal total is the sum of the frequencies for a row or a column in a two-way table, representing the total for that category.

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 categories from the two variables.

Front

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

Back

Interpreting data involves analyzing the frequencies, calculating percentages, and identifying trends or relationships between the variables.

Front

What is conditional probability in the context of two-way tables?

Back

Conditional probability is the probability of an event occurring given that another event has already occurred, often calculated using the relevant row or column totals.

Front

What is the difference between relative frequency and absolute frequency?

Back

Absolute frequency is the count of occurrences, while relative frequency is the proportion of occurrences relative to the total.
