Quantative Data can be used to describe how physical factors might affect the distribution of organisms in a partcular habitat
Quatative data obtained by;
- Random quantative sampling using a quadrat
- sampling along a transect
A quadrat is square frame made from metal or wood which can be subdivided into a grid
Sample size is important. in alarge field enough random quadrats must be placed to be sure the sample is respresentative of the whole field
An estimate of e.g. daisies is usually given as a mean per square metre
A transect is not random. a line is marked between 2 points, and then a quadrat can be placed every 5 metres down the line for example.
