Key Statistical Measures
Mean = Σx / nDescriptive statistics summarize a data set with a few meaningful numbers. The mean shows the center, while the range and standard deviation show the spread.
These measures help you compare groups, spot outliers, and communicate findings clearly without plotting every point.
Frequently asked questions
What is the difference between mean and median?
The mean is the average of all values; the median is the middle value when sorted. The median is less affected by extreme outliers.
When should I use the mode?
Use the mode when you want the most frequently occurring value, common in categories and discrete counts.
Why does spread matter?
Two data sets can share the same mean but behave very differently; spread measures reveal that difference.
