Lesson 1: Picture graphs# Data: FAQ

Frequently asked questions about data.

## What is a picture graph?

A picture graph is a type of graph that uses pictures or symbols to represent data. For example, you might have a picture graph that shows how many apples, oranges, and bananas you have. Instead of using bars or lines, the graph might use pictures of the fruits to show the quantities.

## What is a bar graph?

A bar graph is a type of graph that uses bars of different lengths to represent data. The lengths of the bars show the quantities or values of the data. Bar graphs are often used to compare different categories of data.

## What is a line plot?

Line plots are a type of graph that display data as points above a number line, showing the frequency of each value

## What's the most important thing to remember when making a graph?

We need to make sure that the graph is accurate and easy to understand. This means choosing the right type of graph, labeling everything clearly, and using the right scale.

## Where are these types of graphs used in the real world?

We see these types of graphs all the time! Businesses might use them to track sales over time, scientists might use them to study changes in temperature, and sports teams might use them to compare player statistics.
