Standard Deviation

​(04) Rounding: Significant Figures and Decimal Places​    

In time you should know or recognise approximations of many of these quotients to three decimal places

You can randomise your selection of data if you want to work on season-based statistics:

 1. Determine a 16-game schedule by coin toss and by rule. Heads for Home; Tails for Away.

 2. The second game is fixed as being the obverse of the first and thereafter the running total  between them cannot differ by more than two. You can finish with two Home or two Away games.

​ 3. Determine your first game by any method you choose and work with this and the next 15 games

​ 4. For example you could roll percentage dice, or an ordinary die..a 3; then start from 31 or 33..

Percentages and Probability

​​​Hound out Data012 in Data Files - American Football (above) for more practice with tasks such as simplifying fractions, converting fractions to decimal percentages, ratios, and Quarterback Passer Rating QPR​ calculations...

Also use these figures or derived statistics for practice identifying quartiles, interquartile ranges and outliers.​​

If you randomise your selection of Data for a season set, you can establish statistics for both "For" and "Against"..

​More About Percentages

​If you want to calculate the area of a circle, the volume of a cylinder or swept by a piston, or the circumference of an Apple Pie, then you need to know that the value of Pi is 3.1415926536 to ten decimal places..

This section builds on the Distribution section above, which should be considered first. 

This project looks at particle motion based on an imaginary train in the 1880s worked by "Fenchurch" on the South London Line from London Bridge to London Victoria.  Employs use of formulae, SI and Imperial measurements, decimals and fractions, and with many unit conversions...
