Study Notes
Experiment Design
- Experiments are subsets of a larger project framework
- Each experiment has its own framework, which is a subset of the larger project framework
- The experiment project framework establishes the reasons for the experiment
- The framework defines what type of experiment is needed.
- How the experiment will be designed
- How data will be analyzed
- Desired outcomes of the experiment
- How experimental results should be interpreted
Project Framework
- A project has many individual experiments
- A project has an overarching, surrounding framework that governs many choices within the project.
- Data importance and system choice are dictated by the project framework
Experimental Framework
- Experiments are designed to answer specific questions or hypotheses.
- The experiment's framework guides the design of the experiment in answering the question or hypothesis.
- Experimental data should be predictive and reproducible
- Successful experiments lead to a model that answers the overarching project question
Negative Controls
- A negative control is an "unperturbed" control
- Negative controls isolate the effect of a specific variable (X)
- Negative controls control for other possible variables that could impact the results.
- Negative controls are not only "unperturbed" but they also control for perturbations other than the variable of interest.
Positive Controls
- Positive controls test if the experimental system is functioning as expected.
- They showcase that a system can be used to measure change
- Positive controls provide a valid comparison for experimental results.
- The results of the positive control validate every aspect of the system/experiment.
Eliminating Other Variables
- Identifying and controlling other variables that may affect results
- Eliminating potential for extraneous variables to affect measurements
- Variables are controlled to test the effect of the variable of interest (X) alone.
- Examples include baseline blood pressure, caffeine levels and similar factors.
Statistical Considerations
- Statistical tests used in experiments; group size
- Statistical treatment of data is dictated by validation experiments
- Group size, comparisons, and probabilities are defined through validation experiments.
