This course starts by looking at lists of data. We learn how to find the middle of that data set (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.
The Foundation level course focuses on the core ideas that are important for this topic, while this Standard course will cover the same core ideas but will also include some harder questions that require more application of the core ideas.
Hope to see many of you soon in class! Mr S (:
