Controlling Extraneous Variables: Transcript

Environmental issues Naturally occurring variables usual with several groups of people Noise Temperature Light Time of day Seating arrangements Artificiality Classroom or Office are not real world or natural. Another way to think of this is that these are variables the influence the outcome of an experiment though they are not the variab les that are actually of interest These variables are undesirable because they add error to an experiment A major goal Research. :.
