Statistics KS3 Dice Knock-out Using either one or two dice, the game involves making predictions about the outcome of the roll.  Screen shows one or two dice, or a coin displaying H or T. Can be used with a class. Eg, have people guess if the roll will be a prime number, a multiple of 3, etc.
Statistics KS3 Dice Race** Kids can bet on the outcome of this pseudo-horserace. Each of the numbers from 1 to 12 are runners in this race, where a horse gets to move forward if its number is the sum of two D6s. In most cases, of course, number 7 will come in the top 3. Now includes 3-Dice version, How Many Heads coin version and relative frequency record log option.
Statistics KS3 Fruit Machine A simple version of a fruit machine - click the button and see what colours show up. Useful for an interactive probability demonstration. Includes graphics of tree diagrams to show the range of options.
Statistics KS3 Lose the Counters** A number of counters must be distributed across the numbers 1 to 12, and a counter is removed when its number comes up as the sum of two dice. Experiment to find the optimal distribution of counters to minimise moves.
Statistics KS3 Probability Simulation Demonstrates the nature of large samples for a probability distribution. Originally set up with the probabilities for the sum of two 6-sided dice, the outcomes and probabilities are completely customisable, and the number of trials can be altered. Pressing F9 runs the trial afresh, and the reliability of large samples is made clear.
Statistics KS3 Probability investigation** A homework task requiring students to throw a pair of dice thirty times (or use random.org to do it for them). The investigation is intended to alert students to the fact that some totals are more common than others, and begin to get them thinking about why. Could be incorporated into whole class results subsequently.
Statistics KS3 Random Grid** A visual representation of randomness. A simple application of conditional formatting to show up in a grid (either a 10 by 10 or a 50 by 100 grid) the outcome of any simple binomial experiment. Set the probability (eg 1/6) and each square will change colour with that probability. Press F9 to refresh.
Statistics GCSE Counting Fish** An introduction to the Lincoln Peterson index method for estimating populations. Fish are caught, tagged and released. A second sample is taken and the proportions used to infer the size of the total population. Relative frequency gives an estimate for probability which in turn predicts relative frequency. Can be used in conjunction with Counting Fish excel simulator.
Statistics GCSE Counting Fish** Can be used in conjunction with Counting Fish worksheet. Allows the user to choose how many fish to tag and how large the sample taken subsequently should be, and awards payment based on the accuracy of predictions. Uses macros.

Statistics KS3 Piggy Sixes Roll a die as much as you like, to rack up a score of 100.  Roll a 6 before you bank for your turn, however, and you forfeit that turn's accumulated points.  Available as a 1- or 2-player game.
Statistics GCSE Monty Hall Problem 1** This classic probability problem goes against intuitive thinking.  The first step is to convince the audience that switching doors is a good idea (use the interactive spreadsheet to play the game).  The second step is to explain why (use the accompanying presentation to illustrate the way probabilities change as new information is revealed).
Statistics GCSE Monty Hall Problem 2** To accompany Monty Hall presentation.
Statistics GCSE Take it or leave it** Ever tried to choose the biggest dessert at a restaurant, when they come out one by one? The theory of algorithms for choosing the best of a set of items when you only have the option to choose one at a time is an interesting one to investigate. Uses macros.
Statistics GCSE False Positive** Using conditional probability and talking through all the steps, investigating false positive and false negative rates and what they really mean for medical tests. Uses tree diagrams and Carroll diagrams.
Statistics KS3 False Positive Venn A Venn diagram version of the False Positive worksheet, using the diagram to interpret false positive results and determine the chance of being sick given a positive test result rather than the other way around. A notoriously confusing concept, made easier by considering frequencies rather than abstract probabilities. Full solutions included.
Statistics KS3 Coin Toss Challenge Toss a coin 20 times and record the results (HTT…), but first, cheat - write a series of Hs and Ts that seem random, and see if your teacher can guess which was the coin and which was you. Based on the fact that true randomness throws up more runs, and longer ones, more often than we naturally expect.
Statistics KS3 Flag Venn Diagrams Introducing the concept of Venn diagrams for categorising various flags. Includes questions on probability which the diagrams help you to answer. Full solutions included.
Statistics KS3 Introduction To Probability** An excellent introduction to some of the history and usefulness of a rigorous approach to chance and uncertainty.
Statistics KS3 Probability Investigation** For students to complete, investigating the distribution of scores when adding the total of two dice. While one individual's results may not be too convincing, average a whole class's results and it'll be remarkably close to the theoretical distribution.
Statistics KS3 Probability Investigation Coins** Like the dice version, this requires students to count the number of tails when 6 coins are tossed. Yields a binomial distribution.
