Document Summary
Experiment: reaction time and movement time program, calculated mean, median and sd, frequency histograms to represent mt and rt and scattergram to illustrate relationship between mt and rt, correlation procedure in sas. Was one a better representative of central tendency: median is a better representative because mean is affected by extreme scores. What does the correlation coefficient r suggest about the relationship between rt and mt: r measures strength and direction of a linear relationship. Describe them: the cns consists of the brain and the spinal cord, the pns consists of nerves that carry impulses to/from the spinal cord and the brain. Pns is also divided into the somatic nervous system and the autonomic nervous system. The somatic system is voluntary, it allows us to consciously control body movements. The autonomic system is involuntary as it manages functions we cannot consciously. Identify for main regions of the brain and discuss their function.
