2 of:
1. ref. to adding sample to slide;
2. ref. to idea the sample is uniform;
3. ref. counting cells;
4. ref. to any detail of counting e.g. exclusions / number of squares;
2 of:
5. ref. to grid volume 0.2 mm × 0.2 mm × 0.1 mm = 0.004 mm3;
6. ref. to factor × 250 to estimate number of cells per mm3 / dividing by the
grid volume (0.004 mm3);
7. ref. to counting min.3 areas / slides and taking mean;

AndrewCedric:
dependent= what u observe
independent= what u change

example--> The rate of photosnthesis is dir. prop. to co2 conc.

co2 conc = independent
rate ( time )= dependent
