Understand variables, data representations, measures and spread in Year 8 Maths
Start here
Focus on mean median mode and range. Open support for “Calculate the Interquartile Range”, then explain the idea in your own words.
Year 8 learners practise mean median mode and range.
The activities include Calculate the Interquartile Range, Choose the Most Suitable Average in Different Scenarios, Find and Interpret Cumulative Frequency, and related practice. The checked support below includes practice, teach, video, worksheet. Open a resource in its provider's website and choose the format that best helps the learner explain the idea independently.
