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.

How do you calculate the probability of an event?

Back

Probability is calculated as the number of favorable outcomes divided 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 probability of the other event occurring.

Front

What is the formula for finding the probability of two independent events occurring together?

Back

P(A and B) = P(A) * P(B) where A and B are independent events.

Front

How do you find the total number of outcomes in a two-way table?

Back

To find the total number of outcomes, sum all the frequencies in the table.

Front

What is the probability of selecting a male from a two-way table with gender distribution?

Back

The probability is calculated by dividing the number of males by the total number of individuals in the table.

Front

What does a cell in a two-way table represent?

Back

A cell in a two-way table represents the frequency count of occurrences for a specific combination of the two categorical variables.

Front

How can you determine the number of people who prefer a specific option from a two-way table?

Back

You can determine this by locating the corresponding cell in the table that represents that option and reading the value.

Front

What is the significance of the total row and column in a two-way table?

Back

The total row and column provide the overall counts for each category, helping to understand the distribution of data.

Front

How do you interpret the results of a two-way table?

Back

Interpreting results involves analyzing the frequencies and probabilities to understand relationships between the two variables.
