What is the suggested minimal sample size for survey research?

The suggested minimal sample size for survey research often starts at 100 to ensure that the data collected is statistically significant and provides reliable insights. This sample size allows for a more accurate representation of a population, helping to capture the variability within that population. A sample size of 100 also helps improve the reliability of various statistical analyses, allowing researchers to detect relationships and differences effectively while reducing the margin of error.

In contrast, smaller sample sizes, like 30 or even 15, tend to limit the robustness of the findings and may result in higher variability, which can lead to less generalizable results. Although some exploratory studies might use smaller samples, for confirmatory research or studies aiming for generalization, a minimum of 100 participants is often recommended. This larger sample provides enough statistical power to draw meaningful conclusions from the data collected, making it a standard guideline in survey research methodology.
