3. A researcher is preparing a new study and determines that she will be conducting a single sample t-test, and her effect size will be .50. a) How many total participants does she need to reach a power of .85 with an alpha = .05? b) Interpret your answer to Question 2a. In other words, what does a power equal to .85 mean in the context of testing a hypothesis?

a)A psychologist is planning a study on the effect of motivation on performance on an attention task. In this task, participants try to identify target letters in a stream of letters passing by at a rapid rate. The researcher knows from long experience that, under ordinary experimental conditions, the population of students who participate in this task identify a mean of 71 of the key letters, that the standard deviation is 10, and that the distribution is approximately normal. The...

A physician at the veterans’ hospital would like to try a new MAOI (monoamine-oxidase inhibitor) drug for his veteran patients diagnosed with PTSD. He wondered if MAOI would affect the frequency of nightmares for this patient population. He first asked 16 of his patients with PTSD to record each incident of a nightmare for 1 month before treatment. Participants were then given the MAOI medication for 6 weeks, and then they were again asked to record each occurrence of a...

Instructions: In 1974, Loftus and Palmer conducted a classic study demonstrating how the language used to ask a question can influence eyewitness memory. In the study, college students watched a film of an automobile accident and then were asked questions about what they saw. One group was asked, “About how fast were the cars going when they smashed into each other?” Another group was asked the same question except the verb was changed to “hit” instead of “smashed into.” The...

A study was conducted using undergraduates at a rural university who volunteered to participate in the research as partial fulfillment of a course requirement. One of the items studied was the amount of alcohol consumed (in drinks) in any one day for the past month. Administrators want to know if there are differences in alcohol consumption between freshmen and juniors. Based on the information in the table below, what can be concluded with α = 0.05? freshmen juniors 1 =...

A) A child psychologist conducts a study to test whether infants born prematurely begin to walk earlier than do infants in general. If the research hypothesis is actually true – infants born prematurely do begin to walk earlier than infants in general – and the psychologist has a 25% chance of making a Type II error, what is the power of the study? (give your answer as a proportion - between 0 and 1) B) If there really is NOT...

In a study of memory process, rats were first presented with a fear-inducing stimulus on a learning task as soon as they stepped across a line in a test chamber. Afterwards, the rats were divided and given electrical stimulation either 50 or 150 milliseconds after crossing the line. In addition, the rats differed in terms of the area in which the stimulation electrodes were implanted in their brains (Neutral Area, Area A, or Area B). Researchers were interested in the...

Research is an integral part of all professional fields. Designing a research study can be a complicated task that can be simplified if the appropriate techniques can be identified. This assignment will give you the opportunity to design an experiment, including finding relevant prior research, determining the appropriate sample, data analysis techniques, and discuss the results you hope to see. Working from the topic chosen earlier in the topic selection, you will be designing your own statistical study. In a...
