The Biologist's Experiment

A biologist is investigating the effect of potential plant hormones by treating 20 stem segments. At

the end of the observation period the following length averages were computed:

Compound X = 1.18

Compound Y - 1.17

Based on these mean values it was concluded that there are no treatment differences.

1) Are you satisfied with this conclusion? Why or why not?

2) If you were asked for help in analyzing these data, what statistical method would you suggest to

be used to come to a meaningful conclusion about the data and why?

3) Are there any other questions you would ask regarding this experiment, data collection, and

analysis methods?
