# Statistics and Probability

## AIDS-HIV StatisticsAge: 13+ Time:30-40 minutes. Practice interpreting statistics and graphs, percentages and ratio and have a look at some real data about HIV and AIDS worldwide. Students are given eight pieces of information about eight different countries and asked to sort them in to a different group for each country. Statistics tell stories and | |

## Interpreting World Statistics | |

## Comparing Data DistributionsAge: 14+ Time:1-2 hrs. Use this fun, fictional set of results on a number of levels! Processing data, calculating averages, quartiles, ranges and more. Most importantly this resource is great for comparing distributions. The data is full of surprises and two sets might have some things in common and other things really quite different! | |

## Grime Dice | |

## Olympic Circles | |

## Double Spinner | |

## Minesweeper | |

## The Great Elf Game Have some great seasonal fun with this probability game. Students play with their understanding of chance, arithmetic, percentages, spreadsheets and business sense in an attempt to be the most successful Christmas tree seller on the block. Lotteries, strikes, income tax and all kinds of risk come in to play. Lots of fun and plenty of thinking. | |

## Number Ones | |

## Wisdom of the crowdAnyone can take part! Ask 100 people to guess the number of sweets in a jar and then average their answers. How close will it be? This is an experiment to try and collect lots of data from all around the world to test this theory out. The real jars are touring, but you can take part with videos and photos here. Access the live data and use it for teaching statistics at lots of different levels. | |

## Probability Trees | |

## Guess My Colour When we play games of chance we get a more intuitive feel for probability of events happening. This activity is the first of a series of three probability experiments to carry out | |

## Roll 'em Roll, roll, roll… This carefully structured activity aims to get students to discover that experimental probability approaches theoretical probability as we increase the number of trials. We often overlook the importance of carrying out games of chance to build up an intuition for probability. In this case we roll a dice then use a lifelike simulator on Excel to produce up to 2000 rolls. | |

## In a Spin This is the third in a series of three practical probability experiments. The aim of this activity is to show that the more times you carry out an experiment, the closer the experimental probability approaches theory. Students will use a free online virtual manipulative to be able to carry out a spinner experiment hundreds of times and make the important discovery. | |

## Scattertastic This activity makes use of two excellent virtual mainpulatives that are freely available on the web. The activity helps students to begin understanding the concepts of correlation, lines of best fit and degress of correlation through the use of these manipulatives. | |

## Sprinter or Endurance Runner? This activity gives an insight into how statistics are used by Sports Institutes to select talented youngsters and decide which sport/event they are best suited to. A video demonstrates how to use football player's statistics to draw a stem and leaf diagram in Excel. Students then use data from the IAAF to analyse the heights and weights of sprinters versus endurance runners. | |

## Dynamic Scatter Graphs Statistics can be an emotive subject when the data is real and meaningful. This activity explores dynamic scatter graphs to search for relationships between fertility and life expectancy, HIV rate and income, amongst others. Students will need computers with internet access to use the wonderful gapminder.org website. | |

## Mistigri There are so many games of chance that catch out our intuition. Consider the next possible moves when two players approach the end of this card game where the goal is to make pairs and not be left with the odd one out (Mistigri, the cat). The aim is to work out the probability of not losing and, since the outcome depends on what the previous player has just done, it practises conditional probability. | |

## Predict the Future This activity explores time-series data and shows how calculating and plotting moving averages can help to iron out fluctuations and spot trends. Students will critically analyse temperatures since the mid 19th century to investigate global warming and the effect of wars on life expectancy. |
