kindly provide any study materials or references that could help determine the sample size for this type of research design.
We need more information. On the quantitative side, the type of statistical test and desired power could range from 2 to 1,000. Then will there be a qualitative study--the methodology impacts what will be done (could be 4 to ???). Everything then ties back to your purpose (e.g., a single within case study or wanting to broadly generalize). There are generic recommendations, but one must move beyond that.
I'd be remiss if I didn't add availability, time, and funding are often the three most important characteristics (i.e., we often must use what is available).
I agree with Dr Coker. Sample size can only be determined for quantitative studies. Make sure you meet the minimum for your quantative part and only go up for any needed change in size. Note his final remark. Best wishes David Booth
In the research, 30 singles of the sample are completed, and the study
As for a percentage of quantum research, the size of the sample is required to be greater than 30 as a condition for completion, a quiet study, and the adoption of statistical hypotheses, and here it differs specified according to the original community to study
Dear sir, David Coker
Thank you for answering my question, your answer has given clarity on what aspects to consider while determining the sample size. but sir could you kindly help with understanding how to decide the power size for the quantitative strand? I understand an inference can be made from the statistical test we are using, but how do we decide whether research can use smaller, moderate, or larger power or effect sizes? can you please provide some clarity and reference on understanding these power and effect sizes and how to calculate them, would be much appreciated. awaiting your response .
Regards,
Shirley Rebecca John.
Dear sir, David Eugene Booth
Thank you for answering my question, I understand that the quantitative strand has to be kept in mind while determining the sample size for mixed methods.

First, what is your purpose?
Secondly, what statistical test are you planning to use? There will be recommendations and power calculations. Many are online, but you could use G*Power for free as well. Here is one example: http://powerandsamplesize.com/Calculators/
You can use a textbook or find guidelines online. I can't give any recommendations because I don't know your plan (e.g. a one-sided t test is different than confirmatory factor analysis, etc.).
