UP:MA19.GDA.10
Vocabulary
- Center
- Median
- Mean
- Spread
- Interquartile range
- Standard deviation
- Absolute mean deviation
Knowledge
Students know:
- Techniques to calculate the center and spread of data sets.
- Techniques to calculate the mean absolute deviation and standard deviation.
- Methods to compare data sets based on measures of center (median, mean) and spread (interquartile range and standard deviation) of the data sets.
Skills
Students are able to:
- Accurately find the center (median and mean) and spread (interquartile range and standard deviation) of data sets.
- -Present viable arguments and critique arguments of others from the comparison of the center and spread of multiple data sets.
- Explain their reasoning on how standard deviation develops from the mean absolute deviation.
Understanding
Students understand that:
- Multiple data sets can be compared by making observations about the center and spread of the data.
- The center and spread of multiple data sets are used to justify comparisons of the data.
- Both the mean and the median are used to calculate the mean absolute and standard deviations
