How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the frequency of a specific category by the total frequency, often expressed as a percentage.

Front

What does it mean if a relative frequency is 86.5%?

Back

It means that 86.5% of the total observations fall into that specific category.

What is the purpose of using two-way tables?

Back

Two-way tables help in organizing data to compare the relationship between two variables and to find patterns or trends.

Front

How can you find the percentage of a specific group in a two-way table?

Back

To find the percentage of a specific group, divide the number of individuals in that group by the total number of individuals and multiply by 100.

Front

What is the total frequency in a two-way table?

Back

The total frequency is the sum of all frequencies in the table, representing the total number of observations.

If 63 males are right-handed, how do you express this as a percentage of total males?

Back

To express this as a percentage, divide 63 by the total number of males and multiply by 100.

Front

What does a high relative frequency indicate?

Back

A high relative frequency indicates that a particular category is common or prevalent within the dataset.

Front

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

Back

Interpretation involves analyzing the frequencies and relative frequencies to understand the relationship between the two variables.

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 calculate relative frequencies.
