About Statistics
Mean (average): The sum of all values divided by the count. Best for normally distributed data.

Standard Deviation: Measures how spread out the data is. Lower values indicate data points are closer to the mean.
Frequently Asked Questions
The mean (average) is the sum of all numbers divided by the count. It's the most common measure of central tendency and is sensitive to outliers.
The median is the middle value when numbers are sorted. If there's an even number of values, it's the average of the two middle values. The median is less affected by outliers than the mean.
The mode is the value(s) that appear most frequently in the dataset. A dataset can have no mode (all values unique), one mode, or multiple modes.
Standard deviation measures how spread out the numbers are from the mean. A low standard deviation means values are close to the mean, while a high standard deviation means values are more spread out.
