Statistics: What can we learn from bar charts and graphs?
What are the features of a graph?
Have a look at this example:
On the page below, look carefully at the graph which shows How many sandwiches are sold every hour. You will see the questions below it for you to answer.
We are able to interpret lots of information from just one graph. This means to understand what it shows.

1) How many sandwiches are sold between 8:00am and 9:00pm? Answer:
2) How many more sandwiches are sold between 12:00pm and 1:00pm than between 9:00am and 10:00am?
