SAT Statistics: Mean, Median, and Mode Explained
Mean, median, mode, range, and standard deviation on the Digital SAT — with the intuition that makes them click.
The Four You Must Know
Mean is the arithmetic average. Median is the middle value. Mode is the most common value. Range is max minus min. SAT tests these directly and through 'which of these changes if…' comparisons.
Standard Deviation (Conceptually)
You don't need to calculate standard deviation on the SAT. You just need to know that it measures spread — tighter data has lower standard deviation, and outliers raise it.
