Respond to the following questions/instructions: (a) How could you improve the precision of this experiment using reasonably priced/accessible equipment? (b) How could you improve the accuracy of this experiment using reasonably priced/accessible equipment? (c) Why is the mean value used to represent the aim? (d) Sometimes a percentage precision (e.g. x/x) is quoted in scientific publications. Why would this not be a good method for quoting the precision of the aim? (Hint: Consider what happens as the aim gets worse.)
