AC9M8ST03
compare variations in distributions and proportions obtained from random samples of the same size drawn from a population and recognise the effect of sample size on this variation
Elaborations
- AC9M8ST03_E1comparing the proportion of students in favour of a proposal for a change in school uniform between different random samples of 50 students from the school population
- AC9M8ST03_E2using digital tools to simulate repeated sampling of the same population, such as heights or arm spans of students, recording and comparing means, median and range of data between samples
- AC9M8ST03_E3using relative frequencies from historical data to predict proportions and the likely number of outcomes in situations such as weather forecasting or the countries of origin of visitors to tourist attractions
- AC9M8ST03_E4investigating the effect that adding or removing data from a data set has on measures of central tendency and spread
- AC9M8ST03_E5investigating First Nations Ranger Groups and other groups’ use of sampling techniques to track biodiversity of species
- AC9M8ST03_E6exploring how the comparison of variations in distributions and proportions from the same population applies to data-driven decision-making and how this relates to training of artificial intelligence systems
