#### A Level Geography Statistical Tests

This lesson has been designed to help A Level students with Spearman’s Rank and Chi Squared test, by going through an example of each step by step. In addition there are some slides discussing when to use the test and what some of the pros and cons are. This typically takes up an hour lesson and the students do find it useful going through it step by step. Slide 14 can be printed off and handed to the students and the word document is the chi squared example handed out to students.

#### Quantitative skills: Spearman's Rank and Chi Squared

This lesson is designed to meet requirements of the Geography AQA A-Level specification on quantitative and qualitative skills. As per my usual format this lesson consists of; - Starter activity to get them thinking about prior knowledge and using this to link to this lessons learning (the learning linked to this is found on slides 12-16 as I set this as for students to work on in study time/homework). - Learning objectives and success criteria that are clearly linked to the specification. - New information on Spearman's rank and chi squared with examples designed to work through as a class or in teams, with supporting worksheet at the very end of the PPT. - Plenary/application task - to consolidate learning from the lesson. - Further reading with hyperlinked websites. - Further study - hyperlink and consolidating exam style question on fieldwork techniques that would be used in coastal areas.

#### S3 Goodness of Fit and Contingency Tables Topic Mat

A mat to summarise key concepts from the S3 topic Goodness of Fit and Contingency Tables (Edexcel). This one is quite big so I put it onto A3 paper! I also include a suggestion for how the mat could be filled out. I usually use it as a plenary – ask the pupils for the key ideas from the lesson and collectively fill in sections over a sequence of lessons. At the end of a topic they have a topic mat from which to revise from. I also photocopy them on different coloured paper so they act as dividers in students’ folders.

#### Hypothesis testing and Chi-squared

This presentation introduces the students to hypothesis testing using normal distribution. It starts by explaining what a hypothesis test is, the key language used and also covers type 1 and type 2 errors. Also included is a presentation that shows students how to use Chi-squared test to find a goodness of fit. It covers all parts of chi-squared from a basic introduction to very clear examples, including using the standard results tables (don't forget to move them to show the answers underneath). It also goes on to contingency tables including Yates' correction. SMART Notebook Express presentations can be used for free by using SMART online or by downloading SMART software, also free, I use it because it allows a more interactive presentation than a powerpoint. Just search 'SMART Notebook Express' and try it with my free SMART resource.

#### Interactive graphs of the Binomial and Poisson Distributions - spreadsheet

An interactive Excel spreadsheet that graphs the Binomial and Poisson distributions, with sliders to affect the probability for the Binomial, and lambda for the Poisson. The graphs update instantly so that you can see how the distributions change as the parameters change. Two further sheets overlays the normal distribution (with the relevant mean and standard deviation), showing how well the normal curve models these distributions. I suggest that it is shown via projector/SWB, and the teacher manipulates the slider to give students a more intuitive grasp of the distributions.

#### Edexcel S2 Revision Cards

These S2 revision cards can be used as an individual or class activity. Individuals can ask friends/relatives to test them using these cards. For use in class, hand out one laminated card per pupil. They circulate round the class, pairing up to ask and answer their questions, then swapping cards and pairing up with someone else. It's a nice active revision lesson. Please do let me know if I&'ve made any errors on these cards.
