I am emailing a link of this to everyone on the class list every week. If you are not receiving these emails or want to have them sent to another email address feel free to email me at jpmccarthymaths@gmail.com and I will add you to the mailing list.

## Test 1

I have the test results. I will bring the tests with me to the next two tutorials: one of which you will attend.

 S/N Test 1 0826 90.5 3811 85.7 7813 85.7 6828 85.7 2521 83.3 6247 83.3 7718 78.6 2942 78.5 7113 76.2 4224 76.2 7472 73.8 2828 66.7 5625 64.3 9704 64.3 5686 64.3 7002 64.3 2263 64.3 8226 61.9 9290 61.2 9372 59.5 1047 59.5 8734 54.8 4136 52.4 4649 52.4 4918 47.6 7807 47.6 4203 47.6 2802 47.6 0418 45.2 4953 38.1 3513 38.1 0833 31 1034 28.6 8558 26.2 7604 9.5
The below is a scatter graph of Test 1 scores vs missed days. The correlation is strong and a statistician would call the effect of missed days on your test score to be large. Of course this doesn’t surprise me in the least. The fitted line says roughly that the average test score is given by $T(d)=77-4d$ where $d$ is the number of days missed. In other words: missing seven lectures and tutorials means that your score is nearly 30 percentage points lower than what it would have been had you had perfect attendance.

## Week 6

In Week 6 we finished looking at differentiation constrained optimisation problems.

## Week 7

In Week 7 we will begin the second part of the module: the intimately linked concept of integration.
