Knowledge
Students know:
- Populations can be compared using measures of center and measures of variability
Skills
Students are able to:
- informally assess the degree of visual overlap of two numerical data distributions with similar variabilities.
- Measure the difference between the centers by expressing it as a multiple of a measure of variability.
Understanding
Students understand that:
- outliers skew data, which in turn affects the display.
- Measures of center give information about the location of mean, median and mode, whereas measures of variability give information about how spread out the data is.
Vocabulary
- Visual overlap
- Measure of variability
- Data distribution
