Discrete Random Variables

Discrete Random Variables

A presentation that shows students how to show discrete random variables in different ways. It also shows how to find the mean and variance of discrete random variables and how to use linear scaling to solve general functions of x. 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

Monty Hall Problem

Monty Hall Problem

A look at the Monty Hall problem in an easy-to-understand way.Great introduction to probability suitable for KS3 up to A-Level.Three doors. Behind one is a car, behind the other two are goats. You pick a door, a goat is then revealed behind another door by the host. You have the option to switch to the remaining closed door or stick. What do/should you do?

Statistics: (S1) Coding or making the variance or mean easier (+ rule sheet)

Statistics: (S1) Coding or making the variance or mean easier (+ rule sheet)

This is a teaching resource to help pupils understand coding and the basics of linear adjustments/combinations and how to calculate back and forward from the original data to the coded data. It comes with a good starter, a look at re-arranging and then why coding is used and how it is used. Links to past exam questions, however, it does not come with lots of questions as at that point of practice, I use our S1 textbook. Also a rule sheet handout!NOTE: Feel free to browse my shop for more free and premium resources and as always please rate and feedback, thanks.

Statistics: (S2) Linear Adjustments, Combinations of random variable, normal / poisson distribution

Statistics: (S2) Linear Adjustments, Combinations of random variable, normal / poisson distribution

This teaching PowerPoint contains 4 whole lessons!Lesson 1: Linear adjustment of random variablesLesson 2: Linear Combinations of random variablesLesson 3: Linear combinations for normal distributionsLesson 4: Linear combinations for Poisson distributions+ Rule sheet HANDOUTThese lessons are very structured, with clear lesson objectives, clear examples and small activities to build understanding of what linear adjustments/combinations do and why the rules are the way they are. The lessons do link to a textbook that I use, however, for copyright reasons I can not publish these exercises, but this is easily substituted for another textbook that you use to accompany your course. I have found these PowerPoints to be very effective in teaching this topic. NOTE: Feel free to browse my shop for more free and premium resources and as always please rate and feedback, thanks.

Statistics: Expectation and variance for a binomial distribution PPT

Statistics: Expectation and variance for a binomial distribution PPT

This is a PowerPoint (lesson two) to go with the previous PowerPoint on expectation and variance to build on looking at how to link the variance and expectation for binomial distributions. The PowerPoint mainly looks at building on understanding and why the formula's work and how to use it.

MEI stats 2 power point presentation

MEI stats 2 power point presentation

This presentation covers the Poisson distribution, The normal distribution, samples and hypothesis testing and Bivariate data. Including approximations and hints and tips. The resource is also extremely useful just before exams if printed out as flash cards to induce mathematical thinking before students enter an exam

Probability and Discrete Random Rariables International Baccalaureate Standard Level

Probability and Discrete Random Rariables International Baccalaureate Standard Level

Enormous powerpoint (107 slides) that covers chapters 22 and 23. Everything can be taught directly from the Powerpoint with example questions and practise questions all included on the slides. Also filled with different interesting probability facts and activities to make the teaching and learning more interesting. This includes Explainations of "The Monty Hall problem", "The Birthday problem", "Penny's game" and many others integrated into the powerpoint with the appropriate topics.

Statistics 2 - 15 min exam question challenges

Statistics 2 - 15 min exam question challenges

A collection of exam question challenges for the Edexcel Statistics 2 specification. Each worksheet consists of 2 or 3 sets of questions arranged in difficulty order. Each set of questions should take between 15-20 minutes to complete. How they are used can be up to the teacher, I have used these as either starter or plenary activities during review lessons where students are given a choice of which set of questions to complete in the 15 minute time limit. Then in pairs or groups work through any problems they may have encountered.

Descriptive Statistics: Describing Data & Variables

Descriptive Statistics: Describing Data & Variables

A power point resource for teachers of biology, geography and environmental science for pupils studying at SCQF Level 7-8, (Scottish Advanced Higher, AS-Level, and above). Of use for helping to achieve a basic understanding of the different terms used to describe data and variables commonplace in literature on the internet. It complements the Geoscience Guides (https://www.tes.com/teaching-resource/guide-to-descriptive-statistics-in-geosciences-11308746).

Discrete Random Variables Topic Mat

Discrete Random Variables Topic Mat

A mat to summarise key concepts from the S1 topic Discrete Random variables (Edexcel). 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.I am creating these resources as part of an action research project at my school looking at preparation for improving students retention across a two year linear course and trying to bring the science of memory into the classroom. If you have used these resources and have any comments/feedback/ideas please comment or contact me - thanks!
