Question

1. valentin is collecting information about the pizza sales in each of his four restaurants in town. he collected the number of pizzas sold for each type. he also noted the amount of money used to buy the ingredients of the pizzas. a) which data is categorical/qualitative (pick at least one)? b) which data is numerical/quantitative (pick at least one)?

Explanation:

Step1: Recall data - type definitions

Categorical/qualitative data describes qualities or characteristics. Numerical/quantitative data represents amounts or counts.

Step2: Analyze part a

The type of pizzas (e.g., cheese, pepperoni) and the ingredients used are qualities or characteristics of the pizzas. So, the data about the type of pizzas and ingredients used is categorical/qualitative.

Step3: Analyze part b

The number of pizzas sold is a count and the amount of money used to buy ingredients is an amount. Both are numerical values. So, the number of pizzas sold and the amount of money used to buy ingredients are numerical/quantitative.

Answer:

a) Categorical/qualitative data: type of pizzas, ingredients used for pizzas
b) Numerical/quantitative data: number of pizzas sold, amount of money used to buy ingredients
