Lesson details
Key learning points
- The mode can be calculated from an ungrouped frequency table.
- The mode can be calculated from a bar chart.
- The mode can be calculated from a line graph.
Keywords
Frequency - The frequency is the number of times an event occurs; or the number of individuals (people, animals etc.) with some specific property.
Mode - The mode is the most frequent value. It is a measure of central tendency representing the average of the values.
Common misconception
Pupils may mistakenly choose the bars which have the same heights to be the mode.
By reminding the pupils of the definition of the mode and asking the question in the context of the data, this should support students.
