Contingency Tables and Chi Squared (OCR MEI Statistics 2 : Chapter 3 Part 2)

This presentation introduces the idea of contingency tables, the Chi-squared hypothesis test. Also included are a collection of relevant past paper questions (and answers) drawn from MEI papers. It is not therefore specific to OCR or MEI and could be used for any maths/stats course where such an introduction is needed.

BTEC Assignment Briefs (1 - 4) Unit 8: Using Statistics for Science

This unit enables the learner to use statistical techniques that are essential for the handling, collection and interpretation of scientific data. This contains BTEC assignments for Unit 8: Using Statistics for Science. All of them have been screened for internal verification. Should you need to adapt this for your teaching you may ask your internal verifier to double check them. They have been written in alignment with the learning outcomes of Unit 8. After download you may change the front cover to your own schools logo.

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.

Chi – Square testing.

Goodness of Fit and Chi Squared.

Introduction to the concept of testing for independence, goodness of fit for discrete and continuous distributions combined with hypothesis testing.

A Level Biology- Stats

A collection of resources I have picked up and adapted along the way when teaching statistic elements of A Level Biology. These resources focus on Chi Squared and Students T Test. The stats booklet I refer to is an unedited version from another user which can be found via a TES search.

Statistics 2

This bundle includes all the topics needed to cover the S2 AQA course including; Discrete and Continuous Random Variables Poisson Distribution Estimation Hypothesis Testing Chi-squared

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.

Chi squared worksheet- A level geography- Rivers

Chi squared worksheet- A level geography- Rivers. Contains an introduction to the purpose of chi squared and then gives a partially blank table to fill in, complete with a writing frame with gaps to fill in the analysis from the critical value table.

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.
