 Calculate statistics   Q12: Work out the mean, median and range of a set of small numbers. Five options. Mean, median and range Numbers on cards Q1: The mean of five numbers is given, four of the numbers are known, what is the unknown number? Q2: The mean and range of six numbers is given, four of the numbers are equal and are known, what are the unknown numbers? Q3: The mean, range and median of five numbers is given, three of the numbers are known, what are the unknown numbers?   Q4: The mean, median and range of three mystery numbers is given, what are the unknown numbers?   Q5: Mean Darts Ben throws three darts. The mean of his scores is 39 and the range is 42. He scored a double 9 with his first dart. What did he score with the other two darts? Don't look at the darts for help. Click on the question marks to see the scores.     Q6: Mean, Median and Range Three small numbers are generated. the mean, median and range are worked out. Hide the three numbers, click on 'change'. Can you work out what the three numbers are? Hide the range: is it still possible to work out the three numbers? Show two of the numbers, what is the third? How much information is needed to enable you to work out the three numbers and the three statisitics?   Q14: Reactions: generate loads of numbers A red or blue circle will appear in the middle of the screen. As soon as it appears hit the correct square button on the left or right; you don't need to click. Your reaction time will be displayed. You must then return to the middle of the screen to get ready for the next turn. Your results will be recorded with the option to print them out.
Interpret statistical diagrams  Correlation: drag the points Drag the circles

Interpreting pie charts
Work out or estimate the numbers. The total for each pie chart is shown.

Q7: One pie chart
Q8: Two pie charts

Correlation
Q9: Correlation resource  The first button shows or hides the points. The next three buttons generate variables with either positive or negative correlation or little correlation. Pearson's correlation coefficient is shown. The next two buttons hide or show the correlation coefficient and line of best fit (with the equation). The remaining buttons change the size of the numbers used. Click on the coordinates to hide or show individual points.

Box and Whisker plots
Q10: One boxplot  Drag the circles along the line to change the distribution. Use theses buttons to hide or show statistical information. From the left: hide/show the box and whisker plot, the quartiles, the median, the mean, the range. The other three buttons change the numbers on the number line.

Q11: Two boxplots : compare two distributions
Click on the 'change button to generate a different distribution.

Q13: Two more boxplots : compare two distributions
In this version the distrbution of the points are different: the upper set of points are more spread out. The statistical information can be turned on or off. The panel of buttons can be hidden; click on the eyes to show it again.
Click on the 'change button to generate a different distribution.
