Statistics [Foundation]

This course starts by looking at lists of data. We learn how to find the middle of that data (central tendency) and determine how spread out it is (measures of dispersion). We then see how to summarise this information in the five-number summary and graph it in the box-and-whisker plot.

Thereafter, we progress onto grouped data, where data is grouped by frequency into intervals. We look at how we can do calculations with data in this form and how we can represent it graphically in histograms, frequency polygons and ogives. We also look at how to interpret these graphs.

Finally, we review the content we have covered in this course and then look at past exam questions. The Foundations class will do fewer examples per class and focus more on the core ideas of the topic.
