Dear Professors and Fellow Researchers,
Please I worked on the effects of cadmium on rice and the effectiveness of biochar for remediation. My hypothesis is
1. Cadmium will cause a reduction in the weight of biomass and grain yield
2. Biochar amendment will improve grain yield and biomass
3. Biochar amendment will reduce cadmium uptake
Please to test this hypothesis what statistical tool will I use? Is it a single linear regression, multiple regression or a correlation test? I have 3 levels of cadmium and 5 levels of biochar
