Marginal, Joint, and Conditional Frequency

In a contingency table, if the marginal frequency of Females is 40 and the joint frequency of Female-Sports is 20, what is the conditional relative frequency of Females who prefer Sports?

• 0.50

• 0.25

• 0.75

• 0.20

In a contingency table, what does joint frequency refer to?

• The total count of observations

• The frequency of a specific combination of two variables

• The frequency of a single variable

• The average of two variables

How is marginal frequency calculated?

• By summing the conditional frequencies

• By averaging the joint frequencies

• By summing the joint frequencies for one variable

• By dividing joint frequencies by total frequency

What is the marginal relative frequency?

• The marginal frequency expressed as a percentage of the total

• The joint frequency of two categories

• The frequency of a single variable

• The difference between two frequencies

Which of the following is a conditional distribution?

• The overall distribution of one variable

• The distribution of one variable within specific categories of another variable

• The total count of all observations

• A single joint frequency

To find the conditional relative frequency, you divide:

• Joint frequency by marginal frequency of the other variable

• Marginal frequency by total frequency

• Joint frequency by total frequency

• Marginal frequency by joint frequency

In a contingency table, if the marginal frequency for Females is 30 out of 100, what is the marginal relative frequency?

• 0.70

• 0.30

• 0.50

• 0.40

If a contingency table shows that 60% of Males prefer Sports, what is the conditional relative frequency for Males who prefer Sports?

• 0.60

• 0.40

• 0.20

• 0.80

What is the total number of observations in a contingency table with a joint frequency sum of 80?

• 40

• 80

• 100

• 60

Which of the following represents the marginal distribution of a categorical variable?

• The joint frequencies of two variables

• The total frequencies for each category of one variable

• The frequencies conditional on another variable

• The overall data set
