Obscurity can eat up a person’s mind; the lack of clarity can be maddening to those who have a working brain. When one can’t think straight or form a coherent thought, they start to feel as though they’ve lost touch with reality. To battle this phenomenon, people find a focus so that they can build For example, if you are interested in studying adult survivors of childhood sexual abuse, interviewing a random sample of 10 people may yield only one adult survivor, thus, you will essentially have a sample size of one and need to continue to randomly sample people until you have interviewed an appropriate number of who have survived childhood sexual abuse. It is recognized as a limitation of this exploratory study that the sample size for responses to the questionnaire is small. This therefore limits the generalizability of the findings. To mitigate this limitation, follow‐up interviews were conducted with five of the participating firms.

This therefore limits the generalizability of the findings. To mitigate this limitation, follow‐up interviews were conducted with five of the participating firms. These post‐analysis interviews served several purposes. The sample size for the chosen parameters should be 16,641, which is a very large sample. To make it a more realistic number, you might consider reducing your confidence level and margin of error.
In other study types sample size estimation should be performed to improve the precision of our final results. – Changing sample size – Adding an interim analysis • stop or go decision at interim • re-estimate sample size at interim – Changing decision thresholds • Can be investigated by simulating the trial many (1000s) times within a computer • Final choice of design can then be made based on operating characteristics 43 Estimating sample sizes from effect size estimates in an exploratory study was nevertheless argued by some to be useful if there was scant literature and the exploratory study used the same design and outcome as the future evaluation [30, 39].

I think those information are for actual study, so it is not fully applicable – Changing sample size – Adding an interim analysis • stop or go decision at interim • re-estimate sample size at interim – Changing decision thresholds • Can be investigated by simulating the trial many (1000s) times within a computer • Final choice of design can then be made based on operating characteristics 43 Exploratory factor analysis (EFA) •Two ways; rule-of-thumb and simulation study. 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 The main disadvantage of exploratory research is that they provide qualitative data. Interpretation of such information can be judgmental and biased. Most of the times, exploratory research involves a smaller sample, hence the results cannot be accurately interpreted for a generalized population.

The issue of sample size for exploratory factor $\begingroup$ In fact, you could even argue that it's the other way around: You need a bigger sample size for an exploratory study because you have more items, probably some nuisance factors, you don't know yet if the communalities are high, etc. Validation studies for personality scales typically involve thousands of people but once you have a good scale, it's supposed to be good for very Although our sample size was sufficient for this exploratory study, a more diverse sample including participants with lower socioeconomic status and more ethnic variation would be informative. A larger sample could also ensure inclusion of a more representative range of apps operating on a wider range of platforms.
