Introduction

By Gina smith

AIM

To investigate which battery , IC Fuel or Powerbat, last longer and if temperature or light effects them. Then choose which battery will be better for space travel.

INTRODUCTION

Statistics are used in everyday life. They are used for pricing items in a shop, working out how many people live in England or even working out which day the bin man will come to pick up your rubbish!

Frequency is the ratio of the number of times an event occurs in a series of trials

METHOD

I will use many different methods to determine which battery will last longer. I’ve decided to use random sampling to get a better and interesting spread of results. I will randomly sample the results using  a computer program. I

To work out the range subtract the highest mid point from the lowest mid point.

To work out the mean average of Powerbat battery life I can divided the total of the XF column by the total of the FREQUENCY column.

Foreign Factors

Foreign factors are factors which may effect the results of the investigation. In my investigation the foreign factors are temperature  and light reading of the labs which the investigation was conducted in.

These graphs show if foreign factors effect battery life. From the graph we can determine that temperature does have an effect because the correlation is positive.

We can also determine that light reading has no effect on battery life because there is no correlation.

CONCLUSIONimage09.png

In conclusion Powerbat is more reliable for space adventures such as UKSA’s. I think this because there are less rouge results. In space if you happen to have a fuel cell which could have allow rogue result you could be in serious danger. Not only has Powerbat more reliable, it has  a higher mean average . This means that its life hours are higher. IC Fuel has a mean average of 10.69 but this is bad I comparison to  Powerbat’s average of 11.27. Although they are both effected by foreign factors Powerbat is the obvious battery to use because of its reliability and longer life hours

    The number at the bottom of the T-shape is called the T-Number. This is the 8 by 8 Number Grid with an example T-shape. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26

    Remember that these are the T-shapes going vertically. Tt = n + (n-9) + (n-18) + (n-17) + (n-19) If we multiply out the brackets, we get: Tt = 5n - (9+18+17+19) Or Tt = 5n - 63 Remember: 'n' is the T-Number in this equation.
