Data handling is an important topic in KS3 Maths. In data handling, making connections can involve finding patterns. Data is usually collected with the purpose of showing connections which might answer a question, test a theory or verify a prediction. These connections can be illustrated by making a variety of diagrams.
Imagine that you gathered some information on the amount of traffic at certain times of the day over the course of a week. Once you have all of your data you will need to organise it, most likely in the form of a graph. Once you've drawn your graph you will start to see patterns - busiest times of the day, quietest times, busiest days, quietest days etc. You may then be able to come up with explanations for these patterns - morning rush hour, shopping day, school drop-off time etc.
Try the following quiz to get some practise making connections. Read each question carefully and be sure you understand them before you choose your answers. It may seem easy, but overconfidence can lead to silly mistakes. Good luck!
