Exploring data: graphs and numerical summaries

psychemedia — Mon, 30 Nov 2009 03:04:24 GMT

This Unit will introduce you to a number of ways of representing data graphically and of summarising data numerically. You will learn the uses for pie charts, bar charts, histograms and scatterplots. You will also be introduced to various ways of summarising data and methods for assessing location and dispersion.

Interpreting data: boxplots and tables

psychemedia — Mon, 30 Nov 2009 03:04:24 GMT

This unit is concerned with two main topics. In Section 1, you will learn about another kind of graphical display, the boxplot. A boxplot is a fairly simple graphic, which displays certain summary statistics of a set of data. Boxplots are particularly useful for assessing quickly the location, dispersion, and symmetry or skewness of a set of data, and...

An introduction to complex numbers

psychemedia — Mon, 30 Nov 2009 03:04:24 GMT

This unit looks at complex numbers. You will learn how they are defined, examine their geometric representation and then move on to looking at the methods for finding the nth roots of complex numbers and the solutions to simple polynominal equations.

Modelling displacements and velocities

psychemedia — Mon, 30 Nov 2009 03:04:24 GMT

In this unit you will see first how to convert vectors from geometric form, in terms of a magnitude and direction, to component form, and then how conversion in the opposite sense is accomplished. The ability to convert between these different forms of a vector is useful in certain problems involving displacement and velocity, as shown in Section...

First-order differential equations

psychemedia — Mon, 30 Nov 2009 03:04:24 GMT

This unit introduces the topic of differential equations. The subject is developed without assuming that you have come across it before, but it is taken for granted that you have a basic grounding in calculus. In particular, you will need to have a good grasp of the basic rules for differentiation and integration.

Modelling with Fourier series

psychemedia — Mon, 30 Nov 2009 03:04:24 GMT

This unit shows how partial differential equations can be used to model phenomena such as waves and heat transfer. The prerequisite requirements to gain full advantage from this unit are an understanding of ordinary differential equations and basic familiarity with partial differential equations.

Differential equations

psychemedia — Mon, 30 Nov 2009 03:04:24 GMT

This unit extends the ideas introduced in the unit on first-order differential equations to a particular type of second-order differential equations which has a variety of applications. The unit assumes that you have previously had a basic grounding in calculus, know something about first-order differential equations and some familiarity with complex num...
