Research project 1 - Supplementary material

Included in this repository is a Python script containing all of the data preparation and analysis.

The script is divided into sub-sections for each of the following tasks in order: - Import of external packages - Specification of input file pathways - Reading in of yield data - Calculation of temporal yield stability values - Creation of yield over time graphs - Calculation of species richness - Calculation of Shannon Diversity Index values - Calculation of species evenness - Correlation testing between all variables - Linear regression testing and plotting - Five-way ANOVA testing (including data standardization) - Creation of histogram and boxplot charts - Linear regression testing and plotting in a more efficient format - Additional work that was not used in the final dissertation: - Considering the difference in the relationship between diversity and temporal stability at different nutrient levels - PCA analysis and plotting - Plotting mean yield over time for each treatment and an overall mean - Plotting a running mean temporal stability value over time
