Document Summary
Save the data on the desktop as lab1-1000436469. csv . Scientific method- prove that a variable (x) causes people to behave a certain way (y) while other variables (z) that might affect behaviour are held constant. Prove that x is causes y while controlling z. To prove x causes y we have to measure the behaviour twice (with ad without x) Progressive error/ practice effect: by doing something multiple times, you get better with practice or worse with fatigue (dart experiment) Procedure for controlling order effects in order to distribute practicing. Abba (run in one way, and do it again the opposite way) Unexplained difference that exists between a true score and an obtained score. The variability in responses is due to unknown factors. Measure repeatedly to give a better estimate behaviour. 210 words, all from psych textbook, all read in the lab= controlled variable. Hypothesis: need for comprehension (x) will slow down reading behaviour (y)
