INVESTIGATION
IC FUEL
To work out the range subtract the highest mid point from the lowest mid point.
To work out the mean average of IC Fuel battery life I can divided the total of the XF column by the total of the FREQUENCY column.

POWERBAT
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.
IC Fuel
To work out the mean you must divide the total of each lab by the amount of results for each lab.
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.
Powerbat
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.
CONCLUSION
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
