Math 2-Unit 10 Midterm Review Two-Way Tables 2024-25

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 analysis of the relationship between two categorical variables.

Front

How do you calculate the probability of an event?

Back

Probability is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.

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 occurrence of the other event.

Front

What is the formula for finding the total number of outcomes in a two-way table?

Back

The total number of outcomes is the sum of all the frequencies in the table.

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 marginal total in a two-way table?

Back

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

Front

How do you find the conditional probability from a two-way table?

Back

Conditional probability is found by dividing the frequency of the event of interest by the total frequency of the condition.

Front

What is the significance of the sample size in probability?

Back

The sample size affects the reliability of probability estimates; larger samples tend to provide more accurate representations of the population.

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 categorical variables.

Front

How can you determine which group prefers a certain option using a two-way table?

Back

By comparing the joint frequencies of the groups for that option, you can determine preferences.
