Discrete Mathematics

A substantial part of this Nuffield Advanced Mathematics option was about algorithms. Students used calculators, or computers with a structured programming language, to turn algorithms into programs. They were introduced to various aspects of discrete mathematics and,...

This item is one of over 25,000 physical resources available from the Resources Collection. The Archive Collection covers over 50 years of curriculum development in the STEM subjects. The Contemporary Collection includes all the latest publications from UK educational publishers.

Discrete Random Variables - Coins

This series of interactive excel sheets explore discrete random variables, in particular those of coins and dice.

The first sheet offers a reminder of Pascal’s Triangle.

Discrete Random Variables: Double or Add?

In this activity students examine how rolling a dice and doubling the score produces a different probability distribution from rolling two dice and adding the scores on the two die. This activity can be conducted experimentally, with the simulation on sheet two of the spreadsheet producing many trials with...

Discrete Random Variables: DRV Venn Diagram

In this activity, students are given a Venn diagram and asked to find eight different probability distributions, one for each of the eight regions in the Venn diagram. The notes give solutions for the regions that are possible.

This resource is part of the Making Stats Vital collection from Jonny Griffiths...

Discrete Random Variables: DRVs from a Bag

This exercise is designed to ensure that students know how to find the expected value, E(X), and the variance, Var(X) for a discrete random variable, and that the probabilities in a probability distribution always add to one. Students are given a selection of numbers and are challenged to establish those...

Discrete Random Variables: the Four-Sided Dice

In this activity students are asked to investigate whether it is possible for a four-sided dice, with positive integer faces including odd numbers, to ever have expectation and variance the same. Sheet two carries a simulation with sheet three providing a search programme to find all possible solutions.

Discuss regression and correlation

This resource is from a collection of Nuffield Maths resources exploring Data Analysis. The demand is roughly equivalent to that in GCE A level. It includes slide shows to introduce the topics, student sheets and teacher notes, as well as other relevant resources.

In the ‘DISCUSS regression and correlation’...

Discussing Data

This resource from SMILE Mathematics contains 18 activities for discussing data. Each activity includes information on the data, discussion guidance, specific questions, extension questions, possible hypothesis and a vocabulary check list.

The activities are split into six areas at three mathematical levels...

Discussing Data Supplementary Materials

These supplementary materials for discussing data contain full colour versions of the graphs and diagrams for all the activities in the Discussing Data Activity Book. The graphs and diagrams are split into the six areas described in the book .
