## Lesson details

### Key learning points

- A box plot allows us to make conclusions about the data set
- Box plots can be compared to highlight similarities/differences in data sets
- The box part tells us about the middle 50% of the data

### Common misconception

Not referring to the context of the question when comparing the data.

Highlight that just saying the median or the middle 50% of data is bigger is of little use unless you know what the data was about. Check that pupils understand the context of the question.

### Keywords

Box plot - A box plot is a diagram that clearly shows the minimum and maximum value of a data set along with the three quartiles.

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.

Range - The range is a measure of spread. It is found by finding the difference between the highest and lowest values.
