Document Summary
Protocol: working documents developed in the lab to convey the structure or flow of an experiment. A protocol is a sequentially detailed and numbered account of your experiment. Always in the lab notebook (never published) Appropriate title that reflects the nature of the experiment. Can be very comprehensive (diagrams, photos, labelling, tables, formulae, instructions for using equipment, calculations, references etc. ) Flow chart: a diagram of the separate steps of a process in sequential order. Information in each box allows us to see what action needs to be preformed in each step. Se when more than one value of measure/replicate: take mean of measurements/replicate. Tukey tests (post hoc test) are used when a significant one-way anova result is obtained i. e. an overall significant difference in group means was shown. Tukey test examines all pair wise comparisons of treatment means. Des(cid:272)ripti(cid:448)e state of dependent (cid:448)aria(cid:271)le e. g.
