Exploratory research is defined as a research used to investigate a problem which is not clearly defined. It is conducted to have a better understanding of the existing problem, but will not provide conclusive results. Exploratory factor analysis (EFA) is generally regarded as a technique for large sample sizes (N), with N = 50 as a reasonable absolute minimum. This study offers a comprehensive overview of the conditions in which EFA can yield good quality results for N below 50. Simulations were carried out to estimate the minimum required N for different levels of loadings (λ), number of factors (f), and For example, the larger exploratory study might look at adversarial behavior in general, and a descriptive study might focus on one hacker or one hacking team to understand their behavior in detail. There are also applied studies that look at effects of applied knowledge on specific cases of operational environments, but see the Applied Research section for more details.
Sample size •Using rule of thumbs: Minimum of 5 per item (Costello & Osborne, 2005). •Simulation study: Guadagnoli & Velicer 1988 (As summarized in Stevens, 2009) Condition Sample size 4 or more loadings > 0.6 Any sample size 10 or more loadings = 0.4 150 Written for students taking research methods courses, this text provides a thorough overview of sampling principles. The author gives detailed, nontechnical exploratory research generally utilizes small sample sizes and, thus, findings are typically not generalizable to the population at large; the exploratory nature of the research inhibits an ability to make definitive conclusions about the findings. For example, a researcher intends to collect a systematic sample of 500 people in a population of 5000. He/she numbers each element of the population from 1-5000 and will choose every 10th individual to be a part of the sample (Total population/ Sample Size = 5000/500 = 10). Qualitative Sample Size. Qualitative analyses typically require a smaller sample size than quantitative analyses.
