Statistics & Data Handling
Collect and organise data, draw bar charts and pictograms, and calculate the mean, median, mode and range.
Overview
Statistics is about collecting, presenting and making sense of data. In Year 7 students collect data, organise it in frequency tables, display it using pictograms and bar charts, and calculate the mode, median, mean and range. Choosing the right chart and the right average — and interpreting what they tell you — is the heart of this topic.
What You Will Learn
- Collect and organise data in a frequency table
- Draw and interpret pictograms and bar charts
- Find the mode, median and mean of a set of data
- Find the range of a set of data
- Choose an appropriate average and chart for a given set of data
Key Vocabulary
Common Mistakes to Avoid
- Forgetting to put the data in order before finding the median
- Confusing the mode (most common) with the mean (the calculated average)
- Dividing by the wrong number of values when finding the mean
- Treating the range as an average instead of a measure of spread
What Comes Next
Year 8 adds grouped data, the mean from a frequency table and pie charts, and Year 9 reaches scatter graphs and probability. This becomes the IGCSE Statistics topic.
Frequently Asked Questions
What is the difference between mean, median and mode?
The mean is the total divided by how many values there are, the median is the middle value when the data is in order, and the mode is the value that appears most often.
What does the range tell us?
The range is the largest value minus the smallest value. It measures how spread out the data is, not its average.
