Interpreting Regression Graphs

Seven examples of regression graphs are given with lines of best fit added. Examples of positive, negative and linear approximation relationships are used. Students are asked to state the correlation then estimate and interpret the intercept and gradient of each graph. The students need to know how to estimate the gradient from 2-points on the line and find the intercept by extrapolation. The task is presented in two forms (1) a write on worksheet and (2) a cut up , mix and match activity. The second option is designed to encourage group work and discussion. There is a set of extension questions, one for each graph that promote further consideration on the strengths and limitations of lines of best fit. Answers are provided in a separate file. The activity is designed to be used with AS Mathematics students however it is accessible to Higher Tier GCSE Mathematics and GCSE Statistics students.

Linear Modeling Projects! (CCSS.HSF.LE.A.1)

This class project is sure to be a hit with any and all of your students! This bundle includes 3 projects in one. All the projects relate around the same idea. Students have been hired as consultants for the Baltimore Ravens, Real Madrid or Monsters University to solve some problems. Students must use the provided data to create a linear regression (line of best fit, least squares equation) in order to determine a correlation coefficient. Afterwards, students identify residuals for each piece of data. After collecting all the necessary information, students are led through questions related to the organization. When I did this in class I gave all three projects and let them choose. The choices were mixed and the students loved that they were able to individualize the days lesson depending on their interests. After students were finished each group received a reporting form. This is the form the &quot;consultants&quot; would hand their employer to summarize their findings. This was absolutely a hit in our class! If you don't want all three I will put each project up individually.

Simulate and compare time series in a spreadsheet

A spread sheet with which students can simulate and graph time 3 different time series (with different seasonal effects, linear trends, exponential trends and random variance) by setting a few parameters. Besides helping the students to get an intuitive feeling for what the different components imply in practice, it can serve as an introduction to the idea of estimation by letting visually replicate a real world time series. A handout is included together with data on the sales of sunglasses which the students can try to replicate in the spread sheet.

Interactive Workbooks

Buy the bundle and save over 60%. This is the wonderful collection of fourteen interactive workbooks, with thousands of possibilities, so you and your students are getting an amazing deal. These interactive resources have been successfully used as starters, plenaries, breakouts, inclusion, differentiation, extensions, peer-to-peer learning, as rich learning points, and to get students speaking, reflecting, and predicting, talking about their work and its applications in and outside the school. Buy them, try them and thrive. Incredible.

Mathematics Statistics 1 Lessons

Mathematics Statistics 1 Lessons This is a set of lessons for S1 Statistics 1 A level Mathematics. The resources includes Powerpoints. Powerpoint include: Learning objectives Questions on the topic Important information written in red boxes to scaffold learning. Topics: Introduction Averages Measures of Spread Correlation Regression Probability Binomial Normal Theory Confidence Interval Revision Poisson I hope you enjoy these lessons, they can be used in the following ways: To deliver a course with reduced planning but not reducing quality of the lesson. As a basis for an observation lesson to save time preparing resources. To give to students for out of lesson learning. To support teachers who are new to this topic, again to reduce planning time. As a bases for your own lessons where you can include exam questions to each presentation. As an activity where the questions can be printed and cut out.

Interactive Workbook Correlation

Part of a wonderful collection of interactive workbooks, this one is about Correlation. There are thousands of possibilities in each workbook, so for about the cost of a cup of coffee, you and your students are getting an amazing deal. These interactive resources have been successfully used as starters, plenaries, breakouts, inclusion, differentiation, extensions, peer-to-peer learning, as rich learning points, and to get students speaking, reflecting, and predicting, talking about their work and its applications in and outside the school. Buy them, try them and thrive. Incredible. The resource is for age 3 upwards and so from experience in piloting in different countries and age groups, we found that Product Moment Correlation would be well over most of their heads (and many of the teachers!) and is therefore not included here.

Edexcel S1 Revision clock

This is a revision activity for Edexcel S1 based on the ideas shared on Jo Morgan's brilliant website http://www.resourceaholic.com/. This was originally shared here http://justmaths.co.uk/2015/10/18/keeping-time/. This activity could be used to help improve students' timing by giving them 5 minutes for each of the 12 questions, to improve memory, or simply to produce a visual revision resource. Each student should be given an A3 copy of the clock with a set of questions. Answers are provided.

Statistics: (S1) Making the Mean and Variance Easier (CODING)

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, thank you.

Statistics: (S1) Interpolation - Estimating the Median (+ worksheet)

This is a whole lesson on interpolation with a worksheet. UPDATED, 18 slides. It includes: A starter activity, that links into why use interpolation and what it is for and then a simple, but clear example of how to use interpolation to work out the median. A further activity linking back understanding to the starter and a couple of key question to assess/check understanding. For further practice, I have either been using the worksheet included, which is a bunch of tables to use for practice or past paper exam questions or both. It includes ANSWERS and a plenary. NOTE: Feel free to browse my shop for more free and premium resources and as always please rate and feedback, thank you.

Statistics: (S1) Regression Lines and CODING (+ resources)

This is a whole lesson on regression lines and a look at coding as well. Coding comes up in three or four topics, but the bulk of my teaching on it is on the topic of making the variance easier. 18 slides + resources. Specifically, this lesson is for teaching what a regression line is, to understand its links to real-life situations (excellent clear teaching slides and examples) and calculating a regression line for a given set, including using coding and a look at interpolation and extrapolation. The lesson does include a starter, lesson objectives, keywords, superb teaching slides and examples, exam questions with mark scheme and plenary.

Statistics: (S1) Product Moment Correlation Coefficient (PMCC) + Resources

This is a whole lesson looking at correlation between variables and how to quantify this, by using the PMCC to do so. The lesson includes some fantastic examples and lots of detailed teaching slides, to help ALL pupils understand a tricky subject. UPDATED, 22 slides. It comes with a starter (quick look back at scatter diagrams) and then onto what the PMCC is and why it is important. A look at the different ways to calculate the formula with a working example for the pupils to go through. I have also attached a Edexcel spreadsheet to go through the table with the pupils, which can be used as a foundation for another lesson if you wanted. I have attached practise exam questions with mark scheme. The lesson also comes with learning objectives, key words, video link and plenary.
