Summarising Data
Calculate and interpret measures of central tendency and spread, such as mean, median, mode, and range. Students use these statistics to summarise large data sets.
About This Topic
Calculate and interpret measures of central tendency and spread, such as mean, median, mode, and range. Students use these statistics to summarise large data sets.
Key Questions
- When is the median a better measure of centre than the mean?
- How does an outlier affect the summary statistics of a data set?
- What does the range tell us about the spread of data?
Planning templates for Essential Mathematics
5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
