Sample size Saturation Qualitative research Interviews Focus group discussions 1. Introduction Saturation is the most common guiding principle for assessing the adequacy of purposive samples in qualitative research (Morse, 1995, 2015; Sandelowski, 1995). However, guidance on assessing saturation and the ...
Carefully selecting the sample size for a research study is one of the most fundamental ways to utilize resources in an ethical manner, maximize impact and
In this research, we utilize a systematic, quantitative approach to study the effect of sample size on the reproducibility and specificity of gene set analysis methods using large scale publically available gene expression datasets.Assume that D...

Quantitative research methods come with effective statistical techniques for determining a sample size. Qualitative research methods currently have no similar commonly accepted technique. Yet, there are steps you should take to ensure you have collected
Indeed, institutional differences in this tail may be a principal differentiator (Glänzel 2013). There is a general agreement in the scientometric literature that, on average, there is a broad relationship between average CNCI values and other quantitative (research income) and qualitative (peer ...
Full size image In former work16, we used the predecessor of the here presented microscope (one detection objective)17 to track cells in developing intestinal organoids. However, the achieved imaging depth was not sufficient to track cells in larger specimens, including mature organoids. The newly...
37 Determination of sample size: Quantitative methods (2) ? Formula to determine sample size depends upon the parameter to be estimated (generally the mean or proportion/rate) ? In non-analytical studies that aim at estimating parameters, three basic questions must be answered to determine the ...
