FAQ
What is the difference between mean, median, and mode?
Mean is the arithmetic average (sum divided by count). Median is the middle value when sorted. Mode is the most frequently occurring value. Each measures central tendency differently and suits different data types.
What is standard deviation?
Standard deviation measures how spread out numbers are from the mean. A low value indicates data points are close to the mean; a high value indicates they are spread over a wider range.
When should I use variance vs standard deviation?
Standard deviation is in the same units as your data, making it more interpretable. Variance (standard deviation squared) is useful in mathematical calculations and statistical tests.
