Im doing AQA biology and there have been some questions on working out percentage cover.. how d you do it ??
Percentage cover= (hits/hits +misses) x100 e.g. This is using a point quadrat. 351 pins were dropped & 174 pins hit the grass, therefore the percentage cover = (174/351)x100= 49.5%
Thank you soo much. Thats loads of help !!
