Frequently Asked Questions
What is the arithmetic mean?
The arithmetic mean is the sum of a collection of numbers divided by the count of numbers in that collection.
Are mean and average the same thing?
Mean is a specific mathematical type of average, though the word 'average' can also refer to the median or mode.
How do zero values affect a mean calculation?
Zeros must be included in the total count of items, which lowers the overall calculated mean.
When is it better to use the median instead of the mean?
The median is often better when a dataset contains extreme outliers, such as in real estate prices or household income statistics.
Can the mean of a set of positive numbers be negative?
No, the mean of entirely positive numbers will always be a positive value.
