3. An investigator wants to arrange the 15 items on her scale of language impairment on the basis of the order in which language skills appear in development. Not being entirely confident that she has selected the correct ordering of skills, she asks another professional to rank the items from 1 to 15 in terms of the ordering which he thinks they should appear. The data are given below: Investigator: \( \quad 123456789101112131415 \) Consultant: \( \quad 132475681091112151314 \) Scanned with CamScanner

A different drug level is administered in each condition. Memory is measured 10 minutes after each subject receives the drug. The following scores are recorded. The higher the score, the better the memory. Estimate the size of the effect. = _________. 0.5109 0.5210 0.5100 0.4328

A diagnostic test for a certain disease has 95% sensitivity and 95% specificity. Only 1% of the population has the disease in question. If the diagnostic test reports that a person chosen at random from the population tests positive, what is the conditional probability that the person does, in fact, have the disease? Are you surprised by the size of the answer? Do you consider this diagnostic test reliable?

A researcher asks participants to solve some math problems. Afterwards, she administers a fake intelligence test and tells the participants they scored low on it, even though she never actually graded it. She then asks the participants to complete a second set of math problems and finds that the participants performed much worse. What is the best test to analyze the results of this study?
