I have a dataset with unique observations for each independent variable and observations at a grouped level for each dependent variable. What is the best model to asses if these two variable are related? I know a hierarchical/multilevel model only works when the dependent variable is at the lowest level. An OLS seems to work, except the residuals are in no way normally distributed. This almost looks like a type of ANOVA would be appropriate. I want to see if there is a statistically significant relationship between the variables, not make predictions given new observations. Here is the data:
MUAC BIODIVERSITY

220 -0.63636364 3.818182
221 -1.17894737 3.818182
Is there any way to relate MUAC and BIODIVERSITY, with BIODIVERSITY as the outcome variable?
