In This Assignment, You Will Apply What You Learned About ✓ Solved
In this assignment, you will apply what you learned about
In this assignment, you will apply what you learned about the scientific method to evaluate the validity of two different health claims. There are three file attachments for this assignment. There you will find and read the GetAnAnswerNow.com posting, a scientific article about zinc's effect on colds, and a table with a short essay question for you to fill out. Read the Hemila, 2011, a published scientific paper, and the GetAnAnswerNow.com health claim, which is a fictional posting on the internet. Fill out the table titled "Evaluating Health Claims" to help you determine how scientific each claim is.
The table will help you to decide: Which steps of the scientific method were used? Which steps of the scientific method were not used? Do you feel that the scientific method was sufficiently used in each article to give credibility to its claims? Why or why not? Answer the short essay question below the table and save the completed assignment to your computer and upload it as a Word file to the Assignment drop box titled "Evaluating Health Claims."
Paper For Above Instructions
The scientific method is a rigorous process that helps researchers frame their questions, form hypotheses, conduct experiments, and arrive at conclusions based on observable data. In evaluating health claims, it is crucial to apply the scientific method to ascertain credibility and validity. In this assignment, we will analyze two health claims: one from a scientific article authored by Hemila (2011), which examines the effect of zinc on colds, and a claim from GetAnAnswerNow.com, a fictional posting. We will assess the usage of the scientific method in these claims and determine the extent to which they deserve our trust.
Evaluating the Health Claims
The first claim we will evaluate is based on Hemila's (2011) research, which suggests that zinc supplements can reduce the duration and severity of the common cold. To assess the validity of this claim, we must analyze it against the steps of the scientific method:
1. Observation
Hemila (2011) provides extensive background on the common cold and previous research surrounding zinc’s efficacy. The observation stage identifies that colds are prevalent, particularly in winter months, and that many patients seek relief through various treatments, including zinc.
2. Research Question
Hemila asks whether zinc supplementation can indeed lessen the duration and severity of cold symptoms. This is a clear and focused research question, aiming to determine a specific effect.
3. Hypothesis
The hypothesis posited by Hemila is that zinc, when taken at the onset of cold symptoms, will reduce the length and intensity of the illness. This hypothesis is derived logically from the previous observations and studies concerning the immune response.
4. Experimentation
Hemila’s study involves randomized controlled trials (RCTs), a gold standard method in clinical research, where different groups receive varying doses of zinc. By applying RCT methodology, he effectively minimizes biases and increases the reliability of the results.
5. Data Analysis
Data obtained from the trials are thoroughly analyzed using statistical methods. Hemila reports significant findings that support the hypothesis, illustrating a correlation between zinc consumption and reduced cold duration in participants.
6. Conclusion
Based on the evidence, Hemila concludes that zinc supplementation does indeed have a statistically significant positive effect on the duration of colds. These findings adhere to scientific rigor and lend considerable credibility to the health claim that zinc can ameliorate cold symptoms.
In contrast, the GetAnAnswerNow.com claim presents a less scientific approach. This claim suggests that taking zinc can cure the common cold, but does so without engaging the scientific method thoroughly:
1. Lack of Systematic Observation
The claim is largely anecdotal, drawing on personal testimonies rather than systematic observations or research-based evidence. This aspect raises immediate questions about its validity.
2. Absence of a Clear Research Question
While the claim implies that zinc is beneficial, it lacks a focused research question or hypothesis which could guide further investigation.
3. No Experimental Evidence
There is no mention of experimental studies or a control group, which are essential for substantiating health claims scientifically. This absence significantly undermines its credibility.
4. Insufficient Data Analysis
The claims made are not supported by data that undergoes scrutiny; hence, they fail to adhere to any established experimental methods. Lacking data analysis undermines the claim’s reliability.
Conclusion on GetAnAnswerNow.com Claim
Ultimately, the GetAnAnswerNow.com claim does not sufficiently employ the scientific method and lacks robust evidence to support its assertions regarding zinc curing the common cold. While it may coincide with anecdotal experiences, it does not fulfill the criteria of scientific inquiry required to be taken seriously.
Responses to Questions
In summary, the evaluation reveals a stark contrast in scientific rigor between the two claims. Hemila's (2011) research demonstrates a strong adherence to the scientific method with well-defined steps leading to credible conclusions. The study’s use of controlled trials and statistical analyses provide a reliable foundation for its health claim. Conversely, the GetAnAnswerNow.com claim exemplifies a lack of empirical research and structured methodologies. The absence of scientific backing renders it unreliable and untrustworthy.
