‘Mathews…we are getting another of those strange ’aw blah es pan yol’ sounds.’
Good communication is essential! We need… - A common language (English) - A platform (lectures, labs, tutorials, email, blackboard) - Some rules and common sense - A comfortable, safe work atmosphere, and fun!
“If you want to learn to think you need a dialogue”
Emanuel Kant, 1786
\[(lab_1 \cdot 0.5 + lab_2 \cdot 0.5) \cdot 0.3 + (test \cdot 0.3 + exam \cdot 0.7) \cdot 0.7 \] - AND you need to pass both the practical and the theory to pass the paper!
‘If you want a statisics lecturer, I’ll do anything I can for you - I’m your man’ (modified from Leonard Cohen)…but:
‘Follow me the wise man said, but he walked behind.’ (also by Leonard Cohen, unmodified)
In plain language: we are here for you, but you first need to do your homework, come to lectures, do the labs, read…
If you want to dig deeper:
Slides are not enough! Not everything is online, if you are not in the lecture, it’s up to you to catch up, this is not an online only paper.

1. Demonstrate an understanding of biological variability and how it is measured and reported.
2. Demonstrate an understanding of sampling.
3. Demonstrate competence in basic biological and ecological data analyses
4. Demonstrate competence in reporting experimental results in a written format suitable for publication
5. Demonstrate an understanding of “significance”
6. Present work at an appropriate academic standard.

Error in sqrt("Peter"): non-numeric argument to mathematical function
function(argument1 = value1, argument2 = value2, ...)
Example: the function round, the first argument are the numbers you want to round, and the second argument the decimals you would like to retain (see lab!)
