Human Mistakes vs. Experimental Errors
Human Mistakes – carelessness Experimental Error –
instrument variation or technique
Random Error – chance variation
Systematic Error – system used for designing or conducting experiment

A Sample Dichotomous Key
1. wings covered by an exoskeleton . . . . . . go to step 2 1. wings not covered by an exoskeleton. . . . go to step 3
2 body has a round shape. . . . . . . . ladybug 2 body has an elongated shape. . . . . .grasshopper
3.wings point out from the side of the body . . dragonfly3 wings point to the posterior of the body.. . . . Housefly
Note: There should be one less step than the total number of organisms to be identified in your dichotomous key.
