Major Assessment 7 - Two-Way Frequency Tables

Front

What is a two-way frequency table?

Back

A two-way frequency table is a statistical table that displays the frequency of different outcomes in two categorical variables, allowing for the analysis of the relationship between them.

Front

How do you calculate the percentage of a specific group in a two-way frequency table?

Back

To calculate the percentage of a specific group, divide the frequency of that group by the total frequency and multiply by 100.

Front

What does it mean if two variables are independent in a two-way frequency table?

Back

If two variables are independent, the occurrence of one variable does not affect the occurrence of the other variable.

Front

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

Back

The total frequency is found by summing all the individual frequencies in the table.

Front

How can you determine the marginal totals in a two-way frequency table?

Back

Marginal totals are found by summing the frequencies across each row and each column.

Front

What is the significance of the joint frequency in a two-way frequency table?

Back

Joint frequency refers to the frequency count for a specific combination of two categories, showing how many times that combination occurs.

Front

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

Back

Interpreting results involves analyzing the frequencies and percentages to understand the relationship between the two variables.

Front

What is a conditional frequency in a two-way frequency table?

Back

Conditional frequency is the frequency of a specific category given a condition on another category, often expressed as a percentage of the total for that condition.

Front

How do you find the percentage of a subgroup in a two-way frequency table?

Back

To find the percentage of a subgroup, divide the joint frequency of that subgroup by the total frequency of the relevant category and multiply by 100.

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.
