This is the third quiz in our Easy series of Eleven Plus maths quizzes on Handling Data. As you will know if you have played the previous quizzes, data handling is all about collecting information (with surveys, questionnaires, tallies and so on), then organising it so that you can represent your finding in the form of a chart or graph.
You will come across data handling in many real-life situations. Whenever you see a chart or a graph, you know that somebody has collected some data and then represented it in a way that makes the results easier to grasp.
The questions in this quiz shouldn’t be too taxing – just make sure that you read them all thoroughly before you choose your answers. There are traps waiting for anybody who clicks an answer without fully understanding the question: make sure you don’t fall into them! Good luck.

Before data (information) can be interpreted as a graph or chart, first you have to collect it! Conducting a survey is one method of collecting information, but there are many others

115 ÷ 10 = 11.5. You have to divide 115 by 10 because you want to find out how many 'lots' of 10 there are in 115: each 'lot' equals 10 footballs: this is the same as adding 'lots' of 10 to itself until you get to 115

11?2 x 6 = 1.5 x 6 = 9

40 is four twenty-fifths of 250, so 4?25 would be used by those who prefer winter. The remaining 21?25 would be used by those who prefer summer

Bar charts, pie charts or pictograms are all equally valid ways to show the information

If nobody chose risotto, then it would have no place on the pie chart – all of the chart would therefore be taken by the other choices
