Assume that you are conducting an experiment in human performance. You have two groups: experimental (the group that receives the treatment) and control (the group that does not receive the treatment). What steps would you take to make a decision about the effectiveness of your experimental intervention?

Answer #1

answer:    The experimental group receives an intervention in an experiment to measure the effect of the change on performance or behavior (dependent variable). In order to establish the effectiveness of the experimental intervention, it is necessary to control to situation or occurrence of a confounding variable. This third variable affects the dependent and independent variable which in turns affect the effectiveness of the experiment and manipulates the results. please give me like, thank you

An experiment was done to test the effectiveness of a drug that is being considered for possible use in the treatment of people who experience chronic anxiety. Fifty people who are chronically anxious are identified through a local health clinic. Twenty-five people are randomly assigned to the experimental group, and they receive the new drug for six weeks. The other 25 people are randomly assigned to the control group, and they receive the commonly used drug for six weeks. After...

Assume that you are conducting an experiment. You are interested in whether a treatment ? affects an outcome ?. Assume that ? is binary—individuals either receive the treatment or they do not. For example, assume that ? indicates whether an individual received medicine intended to reduce cholesterol (at the risk of developing side-effects), and ? is a measure of health. (a) Write down a regression model which you can estimate to investigate your research question. Clearly state what each parameter...

You are conducting an experiment in which you measure two means. Your null hypothesis is that they are the same (i.e. μ1 - μ2 = 0) and your experiment will test this hypothesis with a confidence level of alpha = 0.05. You would like to be able to detect a difference in means of+/- 1 with a probability of at least 0.9. How many samples do you need to test? The standard deviations of the two groups are σ1 =...

You are conducting an experiment to determine whether herbicides that are being used to control invasive weeds have negative side effects on native beetles. For your experiment, you divide a field filled with invasive weeds into two halves and apply herbicide to one of the halves. You then randomly place 10 4x4 m plots in each half of the field and sample each plot to determine beetle density. You determine that there are significantly fewer beetles in the half of...

A team of researchers conduct an experiment to see whether adding the compound Fioretin (FRT) to soil will cause orchids to bloom longer. They take orchids of the genus Cattleya (Cats) and assign half of them to a group that receive FRT and half of them to a group that does not receive FRT. They repeat this process with orchids of the genus Phalaenopsis (Pals). All the orchids are grown under the same conditions inside the same greenhouse. a. What...

During the recent tour the France, the world’s best known athlete bicycles race, some cyclists have been expelled for attempting to enhance their performance by ‘blood doping’  with a synthetic hormone, erythropotein (EPO), that stimulates the production of oxygen-bearing (and fatigue inhibiting( red blood cell. Assume that a mental health investigator at a large clinic wants to determine whether EPO, viewed as a potential therapeutic tool, might allow severely depressed patients to better cope with their depression. Volunteer patients are randomly...
