A national study that examined attitudes about antidepressants revealed that approximately 70% of respondents believe "antidepressants do not really cureanything, they just cover up the real trouble." If X represents the number of people who believe that antidepressants do not cure but only cover up the real problem,find the mean and variance of X when 7 people are selected at random.The mean is -(Type an integer or a decimal. Do not round.)The variance is.(Type an integer or a decimal. Do not round.)Next

A personality psychologist was interested in the relationship between height and income. They found there was a relationship and the effect size was: r = 0.08 in correlational units. Calculate a binomial effect size display(BESD) and then tell me what percentage of people who are tall (like me) you would predict to make more money than the average person. The correlation was randomly generated by eClass, so don't start daydreaming about how much or little you or I will make. Answer:

When you are conducting an ANOVA, the total variance in the dependent variable is divided into variance that is due to differences between individuals _______ groups and variance due to differences _______ groups. Group of answer choices above; within over; between above; between within; between
A factor in determining the usefulness of an examination as a measure of demonstrated ability is the amount of spread that occurs in the grades. If the spread or variation of examination scores is very small, it usually means that the examination was either too hard or too easy. However, if the variance of scores is moderately large, then there is a definite difference in scores between "better," "average," and "poorer" students. A group of attorneys in a Midwest state has been given the task of making up this year's bar examination for the state. The examination has 500 total possible points, and from the history of past examinations, it is known that a standard deviation of around 60 points is desirable. Of course, too large or too small a standard deviation is not good. The attorneys want to test their examination to see how good it is. A preliminary version of the examination (with slight modifications to protect the integrity of the real examination) is given to a random sample of…

One-way or two-way refers to the number of independent variables (IV's) in your Analysis of Variance test. One-way has one independent variable (either discrete or continuous) and two-way has two independent variables (either discrete or continuous). For example, a one-way Analysis of Variance could have one IV (brand of cereal) and a two-way Analysis of Variance has two IV's (brand of cereal, calories). O True O False
