Introduction to Exploring Data
Statisticians do it! And so should you.

Looking for Patterns
The most valuable feature of a dataset may be that which is unexpected. Looking at the data in a variety of ways may reveal interesting and surprising patterns.

Stemplots
All you need to know about this useful graphical display. Activities, worksheets and extension material are available from this page.

Dotplots
Dotplots are often the neglected cousin in the family of graphical displays of data. But they are easy to construct and can tell us much about a dataset.

Histograms
Histograms are very useful, but care needs to be taken in constructing and interpreting them. Remarkably, research about histograms is still being conducted.

Measures of Location
So you think the mean, median and mode are boring? Well, maybe, but there are some interesting little side alleys to this topic that are worth exploring.

Measures of Spread
Visit here, and you will learn about some vary useful statistics.

Boxplots
Visit this page and you may possibly learn more than you ever wanted to know about boxplots.

Normal Plots
Not included in Queensland syllabuses, a normal plot of a dataset shows at a glance if a dataset is approximately normally distributed. A very useful display to put in your display cabinet.

Scatterplots
When working with bi-variate data, the absolutely first thing a statistician does is construct a scatterplot. So the absolutely first thing a student working with bi-variate data should do is construct a scatterplot.

Assessment
Some nice assignments and test questions are available here.

Datasets
Students should work with real data. So here is some, available in tab-delimited, Excel 4.0 and NCSS 6.0 Jr formats.

Resources
A smallish collection of the best resources available for teaching and learning statistics. In my opinion.

Linear Regression
Linear regression has the potential to integrate the topics of Introduction to Function and Applied Statistical Analysis in Maths B. This page explains how it can be done.

Normal Distribution
Discover the link between the 1.5*IQR Rule and the normal distribution, and why you should use light bulbs to burn those traditional statistics textbooks.

Probability
Probability is a wonderful subject to teach! There are so many activities for teaching concepts, puzzles and problems with non-intuitive answers and a variety of contexts for the exercises. This page contains a small collection.

Sampling
Contains a nice little activity - the JellyBlubbers - which was modified from a problem in a leading textbook which was modified from an activity in Activity Based Statistics. And the original activity started as a bucket of rocks on the desk of a statistics teacher. An activity with impeccable lineage.

Confidence Intervals
Are you 95% confident that you can correctly teach your students the correct meaning of confidence intervals?

Hypothesis Testing
Teaching students to understand hypothesis testing is a difficult business indeed. This page contains some activities that will give students some hands-on experiences with the underlying concepts.

Curve Fitting
Contains Anscombe's famous dataset, and a comprehensive manual on using technology to fit functions to data.
