What is the sample size of your project?

Hence, determining an appropriate sample size is vital to draw valid conclusions from research findings. However, it is often considere d a difficult step in the design of e mpirical research (Dattalo, 2008).

What do you mean BY SA mple sample size?

Kumar et al. (2013) described sa mple size in terms of the “total number of subjects in the sample” (p. 122). Simply, it refers to the number of respondents or observations to be included in a study.

How big should sample size be for exploratory factor analysis?

For example, exploratory factor analysis cannot be done if the sample has less needs at least 50 samples and generally 100 samples for most research situations (Hair et al., 2018). 1954). Also, a pre-testing and/or pilot study demands a smaller sample size than a main study. et al. (2017); we may revisit this matter in the near fut ure.
