eScience Lab 1 Exercise 2: TESTABLE OBSERVATIONS

Below are several observations that can inform a testable hypothesis. For each of the following observations:

•Determine if the observation is qualitative or quantitative.

•Write a hypothesis and a null hypothesis.

•What would be your experimental approach?

•What are the dependent and independent variables?

•What are your controls - both positive and negative?

•How will you collect your data?

•How will you present your data (e.g., chart, graph)?

•How will you analyze your data?
