Document Summary
Illustrate types of data and associated measurement scales. Understand measures of central tendency and variability. Describe standard scores and their purpose in measurement. Characterized by: bilaterally symmetrical distribution about the center of the curve, mean, median, mode centered on the curve o farther from the curve. Frequency declines in a predictable manner as scores deviate farther and. Right in the middle of the curve there is a perfect-normal curve. Mean, median, and mode will have the exact same value. Not all symmetrical curves are normal: not all bell shaped curves are considered normal, has to encompass characteristics that lead us to think it is a normal curve. The more you add onto the number generator, the more the values of information will fall into a curve. If you had a limited sample size, you would not have a large enough sample to create a curve. Skewness: 1 to +1 o o.
