Document Summary
Scenario: you have gotten a job as a research scientist for a company that makes biofuel from microbes. You are asked to determine whether oil production would increase or decrease if your company changed temperature the microbes are grown in. There are 3 temps regime of interest: 1) open to atmosphere, 2) room temp, and 3) very warm. Experimental design: a detailed plan for conducting an information gathering exercise (an experiment) Determine your response variable (this is what you are going to measure), 2. Determine your treatments (this is what you are going to change, often referred to as factors, 3. Replication (experimental units that are treated identically), 4. Number of sampling events (responses may change through time), 5. randomization (helps ensure that treatments are the primary causal agent of the results, randomly assigned treatments to experimental units, 6. A factor is something you change (e. g. temperature) for each factor you must choose a number of levels.
