Hello

Here are the my chosen topics and corresponding comments and question:

1) Spruce Budworm - My question for this topic is for the number of pupae and the number of months, do we count each number as one category or do we have a range for the counting? - My comment for this topic is that we could convert all the data into numerical variable. Since the data will be normalized, we can use Pearson’s R Correlation Test to investigate the correlation between variables. Also, if we do not want to convert data, or not sure about the correct way of normalizing a data, we can use Spearman’s R Correlation Test instead.

2) Micronutrient Powers - My question for this topic is do we need to worry about the equal proportion from each district in this experiment? For example, do Musanze and Burera need to have same number of children participating in the experiment in order to get an accurate percentage result for comparison? - My comment for testing the effectiveness of MNP is that, since we are comparing a control group (i.e. Musanze or Nyaruguru) versus the MNP-consuming group (i.e. Burera or Nyamagable), we can use paired t-test to analyze the data.
