Learners often confuse key concepts when studying statistics.
They can find it difficult to select from the wide range of techniques available to them and fail to make links with prior knowledge; for instance relating positive and negative correlation to the positive and negative gradient of the line of best fit.
Some learners struggle with unfamiliar data representations. For example, finding it difficult to grasp concepts such as back-to-back stem and leaf diagrams, 3D pie charts and plotting median, upper and lower quartiles on box-and-whisker plots.
Another obstacle can be the language used in statistics.
This unit offers learners the opportunity to gain a better understanding of statistics. They will explore a number of diagrammatic data representations, interrogating them statistically and then drawing conclusions from them.
Throughout the unit learners will experience opportunities to develop their mathematical vocabulary.
This unit of work is just one of several approaches that you could take when teaching this topic, and you should aim to adapt the resources to match the ability level of your learners, as well as your school context.
