SAT Statistics Practice: One-Variable Data Questions

One-Variable Data questions ask you to analyze a single list or distribution of values. These SAT mean median range standard deviation questions focus on center, spread, outliers, and frequency displays.

1. Identify the statistic being asked for before doing any calculation.
2. Order the data for median, quartiles, range, or IQR, and apply frequencies when a table gives repeated values.
3. Decide whether the question asks about center, spread, outliers, or the effect of a change.
