Mathematics — first biennium · Lesson
Mean, median and mode describe the centre of data in different ways. Median requires ordering first; mode is the most frequent value.
In this lesson: Calculate mean, median and mode and deliberately choose a simple measure of centre.
How to proceed: For the mean add all values and divide by the number of observations. For the median sort them. For the mode count repetitions.
You can already assume: Data types, frequencies and fraction operations.

Data: Data: 2, 3, 3, 4, 5
ConceptStep separates what is required from what is recommended or useful as reinforcement. Only required prerequisites block your progress.
Relationships: solid line = required · dashed line = recommended · dotted line = reinforcement.
