Lesson details
Key learning points
- A statistical summary involves the mean, median, mode and range.
- Each summary gives us different insights into a data set.
- Conclusions may be affected by the way the data was collected.
Keywords
Arithmetic mean - The (arithmetic) mean for a set of numerical data is the sum of the values divided by the number of values. It is a measure of central tendency representing the average of the values.
Median - The median is the central (middle) piece of data when the data are in numerical order. It is a measure of central tendency representing the average of the values.
Mode - The mode is the most frequent value. It is a measure of central tendency representing the average of the values.
Range - The range is a measure of spread. It is found by finding the difference between the highest and lowest values.
Population - The population is the entire set of people, creatures, plants or items that make up the whole group which is being studied.
Common misconception
Pupils may believe that as mean, median and mode are all averages that they are all as useful as each other for every data set.
Using non qualitative data to show that the mean and median cannot be calculated, so the mode would be the only option. Showing data sets that have the same mean value but are considerably different to each other.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
