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

Only odd numbers can be used for the wing width, because the "T" always has an equal number of boxes either side of the Middle Number.

    This means again that the formula will have to start with 5*T-Number and end with a subtraction of a number that we will find now. To find this subtrahend we have to methods. I will start with adding the differences between the T-Number and the four other numbers in the T-Shape (T-Number is 24): (24 - 13)

    We now need to use the same method with different grid size to make a universal equation. I have chosen a grid width of 11 as that has a central number as does a grid width of 9, but make it vertically shorter as we do not need the lower number as they will not be used.
