Exploring data: Graphs and numerical summaries

Who is this course for?

Introductory level - no prior knowledge needed

What will I learn?

This free course, Exploring data: graphs and numerical summaries, will introduce you to a number of ways of representing data graphically and of summarising data numerically. 

After studying this course, you should be able to:
- understand and use standard symbols and notation
- understand that data can have a pattern which may be represented graphically
- understand that the standard deviation and the interquartile range are measures of the dispersion in a data set
- understand that the median and the interquartile range are more resistant measures than are the mean and the standard deviation
- identify an overall 'feel' for data and the way it is distributed by constructing appropriate graphical displays.
