Pleurococcus Density vs Direction and Light Lab suggestions

AI Thread Summary
The discussion centers on analyzing the density of the algae Pleurococcus on trees in relation to the direction (North, South, East, West) and the light received from each direction. The user is considering graphing the average light and average density for each direction to identify potential relationships. They note that the data suggests a correlation, particularly that the south direction receives the second highest light and the highest density of Pleurococcus. The user seeks advice on whether this method is effective and if a T-Test would be appropriate for comparing specific data sets. Further details about the project are requested to provide more context for the analysis.

Hi,
I am working on a biology lab regarding the tree algea, pleurococcus and how its density on trees is affected by direction (N,S,E,W) and light received from each direction.

Here is a screenshot of the data I have access to:

My question is: what would you guys think would be the best way to compare the data? I was thinking. Graph the average light received from each direction and graph the average density received from each direction. While that seems to show a bit of a relationship (e.g. on average south gets the second highest light and highest pleur. density). But I was wondering if you guys think there would be a better way to do this? And would a T-Test be a good thing to perform, if so, which two sets of data would I be testing?

Thanks a lot.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
