For this unit, you need to demonstrate the ability to calculator technology to compute summary statistics and access probablities from standard statistical distributions.You also need to:
Interpret diagrams for single variable data, including understanding that the area of a histogram represents the frequency;
Connect to probability distributions;
Interpret scatter diagrams and regression lines for bivariate data, including recognition of scatter diagrams which include distinct sections of the population (calculations involving regression lines are excluded);
Understand informal interpretation of correlation;
Understand that correlation does not imply causation;
Interpret measures of central tendency and variation, extending to standard deviation.
Be able to calculate standard deviation, including from summary statistics;
Recognise and interpret possible outliers in data sets and statistical diagrams;
Select or critique data presentation techniques in the context of a statistical problem.
Be able to clean data, including dealing with missing data, errors and outliers.
