Today we're going to continue working on the write up for the second maths assignment (the exo/endo one).  For the pass criteria, you will need to discuss whether there are any outliers in your data. This can be done in one of two ways:

• Looking at your graph and checking for any point clearly outside the line of best fit
• Calculating the standard deviation and then using that number to give you a 95% confidence interval.  You won't need to calculate these numbers for yourself, but mentioning how they are used will help you gain the pass criteria. Any data point outside these maximum and minimum values is an outlier.

Make sure you have discussed the benefits of using a data logger as opposed to collecting data manually, and read through the assignment sheet before you hand in your assignment.
