Details  2 

You will have 2 sets of data, one for minimum temperature and one for maximum temperature.

These will need to be split into tow files.You can do this in Excel.

The program for part 2 should take the data from one of the files and do the following:

 add all temperatures for one year and count how many there are

Divide the total by the count to get the average

Do this for all years and write this to file - the file should have 2 columns, the date and the average for that date

Repeat this for the other file. 

You should now have 2 files, one for maximum averages and one for minimum averages.

Part 3 will compute the values needed from the formulas I gave you. You will have to do this for both files.
