Document Summary
Logical approach in studying something you observed to gain new knowledge. Aspects: observation, experimentation, communication, write scientific article for journal, orally present at a conference (powerpoint, poster presentation at a conference. Statement of intent about the experiment you"re doing. Experimental design: biology is more important than statistics. 3 basic principles: control, replication, randomization. Hypothesis: tentative explanation of observed phenomenon full latin names. Null is always the one tested using statistical tests: accepted or rejected, hypothesis can never be proved (only supported/disproved, careful when making conclusions based on results. Descriptive statistics: organize/summarize data: mean, sd, se prediction: specific directional statements predicting the outcome. Alternate hypothesis: hypothesis showing a diff/change/effect: observed is different than the expected results. Randomization: every individual in the population has an equal chance of being selected: ensure sample is representative of the population. Protocol: detailed account of the experiment in sequential order: only in lab book, numbered, title, latin name with authority; common name.
