Probability and statistics
Essential Mathematics Year 8
Introduction
This video looks at the language which is needed to be able to describe data which has been gained from a survey. It describes terms such as population, sample, sample size, proportion and bias. It moves on to look at how we can describe the shape of the data using symmetrical and skewed and how to tell if the data is bi-modal. An example is used to describe how to read histograms to answer questions.
