What is the rule of thumb for a sample size and to be considered large?
A general rule of thumb for the Large Enough Sample Condition is that n≥30, where n is your sample size. You have a moderately skewed distribution, that’s unimodal without outliers; If your sample size is between 16 and 40, it’s “large enough.” Your sample size is >40, as long as you do not have outliers.
What is rule of thumb in research?
What is a Rule Of Thumb? A rule of thumb is a heuristic guideline that provides simplified advice or some basic rule-set regarding a particular subject or course of action. Typically, rules of thumb develop as a result of practice and experience rather than through scientific research or a theoretical foundation.
How do you use the rule of thumb?

When to use a rule of thumb for sample size?
Sample size obtained by the rule of thumb will be adequate for any situation involving the Chi-square test during analysis. In addition, it is unlikely that one would under-estimate the required sample size using this approach.
How to determine sample size and statistical power?
six rules of thumb for determining sample size and statistical power Rule of Thumb #1: 4 A larger sample increases the statistical power of the evaluation. Rule of Thumb #2: 4 If the effect size of a program is small, the evaluation needs a larger sample to achieve a given level of power. Rule of Thumb #3: 5
Is there a minimum sample size for multiple regression?
In other applied fields of studies you usually are more lucky with data (if it is not too expensive, just collect more data points) and you may ask what is the optimal size of a sample (not just minimum value for such). The latter issue comes from the fact that more low quality (noisy) data is not better than smaller sample of high quality ones.
What’s the minimum sample size for multiple predictors?
Harris (1985) says that the number of participants should exceed the number of predictors by at least 50. Van Voorhis & Morgan (2007) (pdf) using 6 or more predictors the absolute minimum of participants should be 10. Though it is better to go for 30 participants per variable.
