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.

Exploring Data: Coding Spreadsheet
Coding spreadsheet enables students to analyse the effect of coding data. Students can manipulate the values for x and the frequencies by which each value of x occurs. Students are required to understand and explain why the particular coding has been used. Once the question has been generated students calculate the...
Exploring Data: Outlier Tester
Outlier tester is a very simple but fun spreadsheet that gives students the chance to explore the definition of an outlier using the interquartile range to determine the values beyond which outliers fall. Sheet two provides definitions for determining where outliers fall. By manipulating the outlier values and/or...
Exploring Data: Quartiles for a Small Data Set
Playing with the quartiles for a small data set involves students using the values 1,3,5 and 7 on the spreadsheet to get the target quartile values for sample sizes of 20, 21, 22 and 23. The aim is to note by how much, or how little, difference to the quartiles is made by increasing the sample size by one. Sheet...
Exploring Data: World-wide Statistics
The worldwide statistics PowerPoint begins with a quiz regarding facts about the nations of the world. Students explore the data on the World figures spreadsheet to find the answers to the questions posed in the quiz. The presentation concludes by providing the answers to the questions and giving examples of...
This Making Statistics Vital collection consists of forty independent activities covering the topics of exploring data, data presentation, measures of centre and spread, probability, discrete random variables, binomial distribution, the Poisson distribution, the normal distribution, sampling and hypothesis testing...
Markov Chains
A Markov chain is a mathematical system that undergoes transitions from one state to another, between a finite number of states.
This resource comprises a spreadsheet which allows students to enter values into the transition matrix and the initial state matrix of 2x2 and 3x3 matrices then perform a number of...
Measures of Centre and Spread: a Small Sample
This activity highlights the difficulty finding quartiles for small samples sizes as there appears to be more than one method to be found dependent upon the book being used. In this activity a sample size of 11 is chosen as finding the quartiles for this sample size is straightforward. Students are told the number...
