Question

which of the following sets of data is categorical bivariate data?

a group of teenagers were asked if they enjoyed vanilla ice cream.

Explanation:

Define the target criteria

Using the Categorical Data and Bivariate Data knowledge points

• Bivariate Data means we are collecting data on two different variables for each subject.
• Categorical Data means the values of these variables are qualitative categories (labels, names, or groups) rather than numerical measurements.

Analyze the first option

Using the Bivariate Data knowledge point

• "The wind speed in a city was recorded every day in a year."
• This measures a single numerical variable (wind speed) over time.
• It is univariate numerical data.

Analyze the second option

Using the Bivariate Data knowledge point

• "Students were asked how many hours they drove last week."
• This measures a single numerical variable (number of hours) for each student.
• It is univariate numerical data.

Analyze the third option

Using the Categorical Data and Bivariate Data knowledge points

• "Juniors and seniors were asked if they prefer fiction or nonfiction books."
• This records two variables for each student:

1. Grade level (Junior or Senior) — Categorical
2. Book preference (Fiction or Nonfiction) — Categorical

• Since it measures two variables and both are qualitative categories, this is categorical bivariate data.

Analyze the fourth option

Using the Categorical Data and Bivariate Data knowledge points

• "A group of teenagers were asked if they enjoyed vanilla ice cream."
• This records a single variable for each teenager: whether they enjoy vanilla ice cream (Yes/No).
• It is univariate categorical data.

Answer:

• (A) The wind speed in a city was recorded every day in a year.
• (B) Students were asked how many hours they drove last week.
• (C) Juniors and seniors were asked if they prefer fiction or nonfiction books. (Correct answer)
• (D) A group of teenagers were asked if they enjoyed vanilla ice cream.
