Content description VC2M7ST01

Mathematics Version 2.0 / Level 7 / Statistics

Content description

acquire data sets for discrete and continuous numerical variables and calculate the range, median, mean and mode; make and justify decisions about which measures of central tendency provide useful insights into the nature of the distribution of data

Elaborations

understanding that summarising data by calculating measures of centre can help make sense of the data, commenting on skewness or symmetry of data and the use of mean and median as representative measures
comparing the mean, median, mode and range of displays of data from a given context, and explaining how outliers may affect summary statistics
recognising how different data sets can have the same measures of central tendency and experimenting with how varying data affects these measures
acquiring continuous numerical data by taking measurement samples during a science experiment, observation or field study, comparing measures of central tendency and identifying any anomalies in the distribution of data
