In this activity, you will analyse a given set of research questions and will discuss the strengths and weaknesses of studying one of the questions with at least 2 types of descriptive and analytical study designs.

Step 1: Review

Review the learning resources for this lesson.

Step 2: Analyze

Analyze the following research questions:

1. Is there a correlation between diet and stomach cancer survival in people aged 50-65?
2. How effective is immunotherapy in the fight against breast cancer?
3. What are the perceptions of residents in rural communities about vaccinations?
4. Are middle/low-income countries more likely to have low rates of COVID vaccine uptake?
5. Was there an increase in mental health disorders as a result of lockdown measures imposed in Italy between March and May 2020?

Step 3: Respond

• Select one question from the list above.
  
• Write a post of 250-350 words in which you:
  

1. Choose at least 2 types of study designs (descriptive and/or analytical) that can be used to answer this question.
2. Discuss the strengths and weaknesses of utilizing each study design to answer the research question.

Step 4: Share

To share your work, click on the “Reply” button under this post and paste your work in the “Message” box. Make sure to reference others’ intellectual property when necessary. All references should follow 7th Edition APA formatting. For further instructions, see the resource on the Himmelfarb Health Sciences Library: APA citation resource (N.B. references are excluded from word counts).

OPTIONAL Step 5: Interact (10 minutes)

If you would like to, you can reply to your peers' posts in a respectful and professional manner. Ensure that your post engages your peers' ideas by including a reflection on their comments, sharing ideas of other potential difficulties and parties involved, or asking thought-provoking questions. If a peer comments on your posting, please reply. To post a reply, click “Reply” on a particular discussion, write your feedback and then click on “Post to forum.”

In this activity, you will continue to build upon previous work by selecting a study design for the quantitative component of your research proposal.

Step 1: Review

Review the research questions which you wrote in Module 2 Lesson 1. Select the quantitative question(s).

Step 2: Respond

Choose the best quantitative study design which will help you to answer the question(s). Write a 200-350 word post in which you:

• Summarize the selected design for the chosen questions
• Give a rationale for its selection

For this activity, you will determine a sampling strategy, sample size, and data collection strategy for the quantitative component of your research proposal.

Step 1: Review

Review the learning resources for this lesson.

Step 2: Respond

Recalling the quantitative research questions, design, and objectives already designed, write a post of 200-350 words in which you explain:

• Sampling strategy with a description of the study population
• Sample size along with:
• Justification for the calculation strategy
• Margin of error and confidence level
• Data collection strategy

In this activity, you will write the first part of the "Data Analysis" section of your research proposal. It will include a description of the type of data you expect to collect in the quantitative component and the analysis strategy(ies) you plan to utilize.

Step 1: Review

Review the following resources from the lesson’s readings:

• Analyzing Quantitative Data for Evaluation
• Quantitative Methods - Organizing Your Social Sciences Research Paper
• Scales of Measurement and Presentation of Statistical Data 

Step 2: Respond

Write the first few paragraphs of the Data Analysis section of your proposal. Your post should be 200-350 words long. Ensure that you include:

• Type of data to be collected
• Appropriate data analysis strategy(ies) to be used for each type of data
