Exploring Frequency Tables in A1 and A2 Steps

What does the term 'frequency' mean in the context of two-way frequency tables?

• The total number of events

• The number of times an event occurs

• The percentage of an event occurring

• The probability of an event occurring

In a two-way frequency table, what do the rows and columns represent?

• Rows represent one category, columns represent another category

• Rows represent totals, columns represent frequencies

• Rows represent numerical data, columns represent categorical data

• Rows represent probabilities, columns represent percentages

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

• The number that belongs to both categories

• The total of a row or column

• The percentage of a category

• The probability of an event

What does the term 'marginal' mean in the context of two-way frequency tables?

• The probability of an event

• The percentage of a category

• The number that belongs to both categories

• The total of a row or column

How is conditional probability defined?

• The probability of an event occurring independently

• The probability of an event given that another event has already occurred

• The total probability of all events

• The percentage of an event occurring

If 40% of 125 snow cones sold were large, how many large snow cones were sold?

• 50

• 40

• 60

• 70

If 32% of 125 snow cones sold were grape, how many grape snow cones were sold?

• 45

• 30

• 35

• 40

What does the term 'relative frequency' mean?

• The percentage of a category

• The number that belongs to both categories

• The total number of events

• The probability of an event

How do you calculate the joint relative frequency?

• Multiply the joint frequency by 100

• Divide the joint frequency by the total number of values

• Divide the marginal frequency by the total number of values

• Multiply the marginal frequency by 100

What should the total of all relative frequencies in a table add up to?

• 50%

• 75%

• 100%

• 125%
