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 analysis of the relationship between them.

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 probability of the other event occurring.

What is the formula for finding the percentage of a part compared to a whole?

Back

Percentage = (Part/Whole) x 100.

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

Back

Results from a two-way table can be interpreted by analyzing the frequencies and calculating probabilities or percentages to understand relationships between the variables.

Front

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

Back

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

Front

What is a conditional probability?

Back

Conditional probability is the probability of an event occurring given that another event has already occurred.

Front

How do you find the probability of a specific outcome in a two-way table?

Back

To find the probability of a specific outcome, divide the frequency of that outcome by the total number of observations in the table.

Front

What is the difference between relative frequency and absolute frequency?

Back

Absolute frequency is the count of occurrences of a value, while relative frequency is the proportion of the total that this count represents.

Front

What does it mean if the probability of an event is 0?

Back

If the probability of an event is 0, it means that the event cannot occur.
