Document Summary
Study guide: you learn of a strong correlation between two variables. If the study design was legitimate in that it sampled randomly and accounted for any confounding variables, then the correlation would be treated seriously. There is a strong correlation between ice cream sales and the rate of drowning deaths. Explain. (b) identify another measure of z that is valid but not necessarily reliable. If a scale is reliable, then it will show the same weight every time, even if it is not the correct weight. If the scale is valid, then it will show the correct weight, but it might not be reliable because it won"t show the same weight every time. Determine the standardized score for a particular given observation. Standardized score: observed score mean/ standard deviation: in reference to a certain sampling frame (to be specified), cite and justify two different ways to draw a representative sample of a certain size.
