This problem is related to Shrub Volume, but using the Pandas library.
Dr. Granger is interested in studying the factors controlling the size and carbon storage of shrubs. This research is part of a larger area of research trying to understand carbon storage by plants. She has conducted a small preliminary experiment looking at the effect of three different treatments on shrub volume at four different locations. She wants to conduct a preliminary analysis of these data to include in a grant proposal and she would like you to conduct the analysis for her (she might be a world renowned expert in carbon storage in plants, but she sure doesn’t know much about computers). She has placed a data file on the web for you to download.
.head()
method.1.8 + 2 * log(volume)
where volume
is the volume of the shrub.
You’ll need to use the numpy
version of the log()
function.The following code calculates the average height of a plant at each site:
data_means = data.groupby('site').mean()
data_means['height']
Modify the code to calculate the average height of a plant in each experiment type.
