These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- The PPDAC cycle is a framework that can be followed when asking and answering real-world problems using data.
- A correlation shows that there is a relationship between two or more variables.
- A correlation doesn't guarantee that one variable causes the other.
- Data that sits outside a trend is known as an outlier.
Keywords
PPDAC - a framework for us to follow when asking and answering real-world problems using data
Correlation - a correlation simply measures how two things move together
Outlier - a data point that significantly differs from the rest of the data in a data set
Common misconception
A positive correlation means one variable has an impact on another.
Just because there is a correlation, it doesn’t necessarily mean that one things causes another to increase.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
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.
