In simple words

Data is facts and numbers collected about things. Like a list of your favorite foods.

The real definition

Data is information—facts, numbers, or observations—collected and stored for use. AI learns by studying lots of data.

Like… Recipe Ingredients List

Data is like ingredients on a recipe card. You collect them, write them down, and use them to cook something new.

But: Recipes are finished instructions. Data is just raw facts without decisions.

You see it every day

on your phone

Photos on Your Phone

Your phone collects photos as data. AI uses thousands of photos to recognize faces.

out in the world

Weather Station

Thermometers measure temperature as data worldwide. Weather AI predicts storms using this data.

at work

Store Sales Records

A shop records every item sold as data. AI uses this data to predict what to buy next.

Check yourself

quick check

Which one is data?

Hint

Data is facts you can count or measure.

quick check

A hospital records ages, heights, and weights. Then AI helps doctors find health patterns. What is the data here?

Hint

Data is the raw facts you gather first.

think

What data does your school collect about you? Why might AI use it?

Show a good answer

Schools collect grades, attendance, and test scores. AI could use this to suggest which classes you might enjoy or predict graduation risk.
