Advanced Higher Geography

Continue your work from last week on the methodology & evaluation sections of your Geographical Study. 

It might also be useful to look at the latest Course Report, which gives more advice on how to score well in the Geographical Study.

This week we'll combine two techniques and collect data which we will later use in some statistical work. Our null hypothesis will be:

"There is no relationship between light level and species richness"

To do this we will collect data in two ways:

• We will use a quadrat to collect information on species richness. Species richness is a measure of biodiversity and is simply the number of different species which are present in a quadrat. (We will also briefly cover other measures which can be made using a quadrat).

• We will use a light meter to collect light levels in lux. This is one technique that can be used in microclimate  analysis. (We will also briefly cover other weather/climate measures that can be used as part of a microclimate study).

We will decide which sampling method is most appropriate for our study - random, systematic or stratified.
