Frequently Asked Questions

What does standard deviation mean?
It measures how spread out data is from the mean. A low SD means data is clustered; high SD means it is spread out.
What is a good correlation coefficient?
|r| > 0.9: very strong. 0.7–0.9: strong. 0.5–0.7: moderate. 0.3–0.5: weak. < 0.3: very weak.
When should I use population vs sample SD?
Population SD for complete datasets. Sample SD (with n-1) when working with a subset of a larger population.
How do I interpret probability?
A probability of 0.25 means a 25% chance of the event occurring. Multiply by the number of trials to estimate expected occurrences.
