1- Using the histograms from your output file, describe the differences in the frequency distributions between the two data sets. For each of the two months, would it be highly likely to sample one more daphnia that has a length identical to the sample median for that month? Why or why not? How does that affect your interpretation of the median as a measure of central tendency?

2- What is the most probable biological reason for the change in mean daphnia length from June to September?

This is the numbers:
