So, you've collected your data but how do you display the information? One way is through frequency diagrams. In this KS3 Maths quiz on data handling we look at how to interpret a frequency diagram and how to create one.
Collected data is of no use unless it can tell us something about the situation surveyed. To see patterns or connections in information we can display it in a variety of ways. Pie charts, bar charts, line graphs, pictograms - these are all examples of frequency diagrams. In them we use a symbol (a 'wedge' of a pie chart, a bar in a bar chart, a point in a line graph or a picture in a pictogram) to show data. This could be the portion of people in a survey who gave a particular answer, the amount of hours daylight, the temperature or just about any other piece of data you want to represent.
To help you with frequency diagrams you can play this quiz. It deals with some of the many diagrams used to illustrate frequency data. Take your time and read each question carefully before picking your answers. Good luck!
