## Organising Data Into Graphs exercise

Would you like to apply the knowledge you’ve learnt? You can review and practice it with the tasks for the video Organising Data Into Graphs.
• ### Which of these pictures shows a graph?

Hints

Remember, a graph shows information or data in a diagram that you can read easily.

Graphs organise different types of data.

Solution

A graph or chart shows information that is easy to read, like this graph that shows how many people enjoy which ice cream flavour.

• ### Read the data on this graph.

Hints

Remember to look at the graph for your answers. Look at the category, then see how many people play that sport.

How do we read a graph? We look at the numbers on the left side. Look at how many children play rugby. What number does the bar reach?

Solution

Most played sport: Football

2 people play: Rugby

• ### Look at the graph to answer the question.

Hints

Look at the graph. Which bar is higher, red or yellow?

Nari was asking what colour their friends liked best. Look at the numbers on the left - which colour is more popular?

Solution

Nari's graph shows that her friends like red more than yellow. This is because the graph shows that 10 friends said they preferred red, while only 5 friends said they preferred yellow.

• ### How do we label a graph?

Hints

Remember, the first thing we have to do is think about what the title should be.

Remember, the numbers go on the left side of the graph. They show how many of each item there is.

Solution

Gus labelled this graph "Ice Cream Flavours", because the categories were vanilla, chocolate and strawberry! Then, he added numbers to the left of the graph, starting at 0 and going up to 6.

• ### Which title makes sense?

Hints

Remember, Gus made a graph of the pets in his neighbourhood. The title of a graph should match its data.

It could not be "Animals In My House", since this is a graph of animals in the neighbourhood.

Solution

The title would be "Pets in the Neighbourhood", since it describes the exact data it shows.

• ### Compare and contrast the two graphs.

Hints

The images in the graphs are: sandwiches, pizzas and salads.

To find which food is the most popular, look for the highest bar.

To compare sandwiches, look at the number of sandwiches eaten by each class, then decide if Gus' class ate more or less.

Solution

In Nari's class, the most popular lunch was salad. We know this because Nari's graph shows 6 classmates ate salad, while 5 ate sandwiches and another 5 ate pizza.

In Gus' class, the most popular lunch was pizza. We know this because Gus' graph shows that 7 classmates ate pizza, while 6 ate salad and 2 ate sandwiches.

Gus' class ate more pizza than Nari's class. This is because Gus' classmates ate 7 pizzas, while Nari's classmates ate 5.

Gus' class ate fewer sandwiches than Nari's class. This is because Gus' classmates ate 2 sandwiches, while Nari's graph shows their classmates ate 5 sandwiches.
