Let's Learn About Graphs! 📊
Graphs help us see data in a fun and easy way. Let's learn how to make them!
Question 1: Super Watch Sales
The table below shows the number of watches sold by a company from July to December. We want to create a graph to see how sales changed each month.
| Month | July | August | September | October | November | December |
|---|---|---|---|---|---|---|
| Watches Sold | 1000 | 1500 | 1500 | 2000 | 2500 | 1500 |
🤔 Why a Bar Graph?
A bar graph is perfect here! We use bar graphs when we want to compare amounts for different groups or time periods. It makes it super easy to see which months had high sales and which had low sales.
✍️ How to Draw It:
- Draw the Axes: A vertical line (Y-axis) for numbers and a horizontal line (X-axis) for groups.
- Label the Axes: Put numbers on the Y-axis and group names on the X-axis.
- Draw the Bars: For each group, draw a bar up to the correct number.
- Give it a Title: A title tells everyone what the graph is about.

Question 2: How Do We Get to School?
This table shows how children from three different schools prefer to travel. We want to compare their choices.
| Preference | School A | School B | School C |
|---|---|---|---|
| Walking 🚶 | 40 | 55 | 15 |
| Cycling 🚲 | 45 | 25 | 35 |
🤔 Why a Double Bar Graph?
A double bar graph is great for comparing two sets of data for the same groups. Here, we can easily compare walking and cycling for each school.
