Project Title: Sample Size Calculation for a Research Study

Overview:

I am looking for a freelancer who can assist me in calculating the sample size for my research study. This calculation is crucial in ensuring that my study yields accurate and reliable results.

Level of Confidence:

I require a sample size calculation with a desired level of confidence of 80%. This means that I want to be 80% confident that the results obtained from my sample accurately represent the population.

Estimated Population Size:

The estimated population size for my study is approximately individuals. Therefore, it is important to consider this small population size when determining the appropriate sample size.

Margin of Error:

I require an acceptable margin of error of 5%. This means that I want the sample size calculation to be accurate within a 5% margin of error.

The primary efficacy variable is a validated questionnaire of 15 questions- each scored 0-3. So the range is 0-45.

We want to assume a placebo response of 15% and 50% response in active participants.

Skills and Experience:

To successfully complete this project, the ideal freelancer should have the following skills and experience:

- Proficiency in statistical analysis and sample size calculations

- Knowledge of research methodologies and study design

- Strong understanding of confidence intervals and margin of error

- Experience in working with small population sizes

- Attention to detail and accuracy in calculations
