Need help with this statistics assignment. Of course not asking for you to do it, just an example or help on how to answer.
Find some information in a book, research article, newspaper, magazine, or online about
any kind of medical research that includes a measure of center or measure of variation. Next, I have to create a binomial experiment.
1. State the kind of medical research in the heading.
2. State the claim to be tested. (For example: Niacin lowers chloresterol.)
3. Describe the binomial experiment you would use to test the claim. Be sure that
you describe how each of the four criteria for a binomial experiment will be satisfied.
Any help is appreciated.
1. Medical Research:
The Effectiveness of a New Drug in Treating Depression
2. Claim to be tested:
The new drug significantly reduces symptoms of depression in patients.
3. Binomial Experiment Description:
To test the claim, a binomial experiment could be conducted with the following criteria:
a) Fixed Number of Trials:
A fixed number of patients would be selected randomly from a specific population to participate in the study. For example, let's say 100 patients are selected to participate in the trial.
b) Independent Trials:
Each patient's response to the drug is considered independent of one another. The outcome of one patient's response does not affect the outcome of any others.
c) Two Possible Outcomes:
Each patient can either experience a reduction in depression symptoms or not. In this case, we assume the outcome is dichotomous, where success indicates a reduction in symptoms, and failure denotes no improvement.
d) Constant Probability of Success:
The probability of success (reduction in symptoms) remains the same for each patient throughout the experiment. Let's assume the probability is 0.7, suggesting a 70% chance of experiencing a reduction in symptoms.
By conducting this binomial experiment, data can be collected on the number of patients who experienced a reduction in symptoms versus those who did not. This data can then be analyzed using appropriate statistical methods to determine if the new drug is effective in treating depression.
To answer this assignment, you can follow these steps:
1. Find information: Start by conducting research in a book, research article, newspaper, magazine, or online about medical research topics. Look for a study that includes a measure of center (such as mean or median) or a measure of variation (such as standard deviation or range) related to the chosen medical research topic. For example, you could search for a study on the effectiveness of a specific medication in lowering blood pressure.
2. State the kind of medical research: In the heading of your assignment, clearly state the type of medical research you found. For instance, you could write "Study on the Effectiveness of Medication X in Lowering Blood Pressure."
3. State the claim to be tested: Identify the claim that the medical research aims to test. This claim should be related to the measure of center or variation mentioned earlier. For example, the claim could be "Medication X significantly reduces systolic blood pressure in patients."
4. Describe the binomial experiment: Now, you need to create a binomial experiment to test the claim. A binomial experiment has four criteria that need to be satisfied:
a. Fixed number of trials: Specify the number of trials or observations to be conducted in the experiment. For example, you could state that you will collect blood pressure measurements from 100 patients.
b. Independent trials: Ensure that each trial/observation is independent of one another. In this case, it means that the blood pressure measurements of one patient should not have any influence on the measurements of another patient.
c. Two possible outcomes: Define the two possible outcomes for each trial. In this context, you could consider a successful outcome as a reduction in systolic blood pressure of at least 10 mmHg after taking Medication X, while an unsuccessful outcome would be a reduction of less than 10 mmHg or no reduction at all.
d. Constant probability: Specify that the probability of a successful outcome remains constant for each trial. For example, you could assume that each patient has an equal chance of experiencing a reduction of at least 10 mmHg with Medication X.
By describing these four criteria for a binomial experiment in relation to your medical research topic, you will fulfill the requirements of the assignment. Remember to include any relevant statistical calculations or analysis in your answer where necessary.
