Stem and leaf diagrams
A stem and leaf diagram shows numbers in a table format. It can be a useful way to organise data to find the median, mode and range of a set of data.
Example
The marks that a class score in a maths test are shown below.

A stem and leaf diagram is drawn by splitting the tens and units column. The tens column becomes the 'stem' and the units become the 'leaf'.
Example of unordered stem and leaf diagram
Stem and leaf diagrams must be in order to read them properly.
Example of ordered stem and leaf diagram
A key should always be provided to help people to understand the data.
The 'leaf' should only ever contain single digits. Therefore, to put the number 124 in a stem and leaf diagram, the 'stem' would be 12 and the 'leaf' would be 4. To put the number 78.9 into a stem and leaf diagram, the 'stem' would be 78 and the 'leaf' would be 9. In this case, the key would indicate that the split between stem and leaf is a decimal.
