usually many independent variables influencing a few dependent variables set up an experiment where only one indepedent variable is allowed to change, measure the effects of that change on the dependent variable analyze the results experimental controls - used for comparison placebo effect statistical and graphical analysis mean, median, mode, and standard deviation scatterplots and histograms t-tests and more advanced statistical analysis modify hypothesis in light of the results from the test as necessary and repeat the deductive step publish findings so can be evaluated by others scientific reports must include the following information the purpose of the investigation or experiment including information concerning the hypotheses to be tested the methods used in the investigation the results of the investigation in a readable form (graphs, tables, etc., are especially helpful) the conclusions drawn from the results: what do the results mean, what changes do we need to make in our hypotheses a few refinements and warnings hypothesis should be simple (Occam's Razor) some experiments may never give clear results are there any untouched field sites - earth ecology?
