How Does Types of Data: Categorical vs Numerical Data Work?

Data is like labels we put on things to help us understand them better.

Imagine you're sorting your toys into two boxes: one for categorical data, and one for numerical data.

Categorical Data, Like Toy Types

Categorical data is when we group things based on types or categories, not numbers. It’s like putting all your cars in one box, all your blocks in another, and all your dolls in a third. You're not counting how many you have, you’re just naming the groups.

Numerical Data, Like Counting Your Toys

Numerical data is when we use numbers to describe something. If you count how many toys are in each box, that's numerical data. It’s like saying “I have 7 cars,” or “My blocks tower has 12 blocks.” You're working with numbers and can do math with them.

So, whether you're sorting your toys by type or counting how many you have, you’re using categorical or numerical data, just like in real life!

Examples

  1. A teacher counts how many students prefer chocolate or vanilla ice cream (categorical), and measures their height in centimeters (numerical).
  2. A bakery tracks the number of cakes sold each day (numerical) and notes which flavors are most popular (categorical).
  3. A survey asks people if they like dogs, cats, or neither (categorical), and how many hours they spend on social media daily (numerical).
