Welcome to this, our second difficult quiz on handling data. If you played the first one, you’ll be familiar with four things associated with data handling: the range, the mean, the mode and the median. These four ideas are used to work out averages.
The range of a set of data is the difference between its highest and lowest values. The mean is worked out by adding all the values together, then dividing by the number of values. The mode is the value which appears most often. Finally, the median is the middle value of the data, if it is arranged from lowest to highest.
As you can see, there are several ways to work out the average value in a set of data. This means that, depending on the method you use, your results might be very different!
So, now we know all about averages, it’s time to put your knowledge to the test. Good luck!
