Large Data Set Quiz - Edexcel A Level Maths
This is a quiz, split into three rounds, on the Large Data Set from Edexcel for the A Level Mathematics course.
The 3 rounds are:
• Round 1 = Locations.
Questions ensure that students know which locations are covered by the large data set and where these locations are found.
• Round 2 = Variables.
Which variables are given for each of the different locations?
• Round 3 = Units and Data
Which units are used for each of the variables and some specific questions on some anomalies in the weather or data?
The quiz is presented in a variety of formats to allow for different methods of delivery to a class:
• Just The Questions
Suitable for administering the quiz in a test format. One file has all rounds in it, and there are three separate files for individual rounds.
• PowerPoints
Two versions of each round have been provided. One where each question is given followed immediately by the answer, and one where all answers are saved until the end of the PowerPoint.
• Answer Sheets
These can be used alongside the PowerPoints, or if the test is being delivered orally.
• Questions And Answers
All questions and answers provided together, either on multiple sheets, or all on one sheet.

Student Test Tracking spreadsheet - single test
This spreadsheet will allow you to greater analyse the performance of your students in a test. It will automatically calculate totals, percentages, grades (according to grade boundaries that you specify) etc. It will also colour-code performances on questions against the maximum marks available and provide you with the opportunity to print out individually tailored feedback sheets to your students.
I have found that this gives me an excellent method for communicating with students about their relative performance, rather than simply telling them that they have achieved 58% for example.
The file will come to you as a password protected document. The reason for this is so that it is not possible to make changes to the formulae and thus make it so that it does not work. You do not need to unprotect it to make full use of it, but just in case you wish to make changes, the password for the file is “table”.
I have made a video demonstrating it and telling you how to use it, which can be found at:
https://youtu.be/G0_WWFINHqM
I also have a larger version available, also on the TES website, for the analysis of up to ten tests, allowing you to compare a student or class throughout those tests.
