Question

How do you know if a sample size is large enough?

Answer 1

Large enough sample condition test can be use to know if a sample size is large enough.

Applicable conditions for this test:

1. Sample size > $40$, without outliers.

2. Uni modal distribution without outliers, when a sample size of $15$ is “large enough.”

3. A moderately skewed distribution, if sample size $>16$ and size $<40$, it’s “large enough.”

4. Normal distribution is considered “large enough”.

Hence, We can know if a sample size is large enough by Large enough sample condition test.
