SAT One-Variable Data: Distributions and Measures Worksheet
One-variable data questions test whether you can compute summary statistics and interpret histograms, box plots, and dot plots without over-computing. This worksheet page turns that skill into a focused review asset: what to know, what to practice, and what to check before moving on.
What this worksheet covers
One-Variable Data: Distributions and Measures belongs to the Problem-Solving and Data Analysis domain on the Digital SAT Math section.
Use this as a one-skill worksheet before timed modules. The goal is not just to get questions right, but to recognize the pattern quickly under SAT timing.
- Official skill: One-variable data: Distributions and measures of center and spread
- Section: Math
- Domain: Problem-Solving and Data Analysis
- Best use: focused drill session before a timed module
Rules to remember
Before drilling this skill, memorize the core rules below and keep them next to your scratch work.
- Median is resistant to outliers; mean is not.
- Standard deviation increases as data points spread farther from the mean.
- Read the axes and scale carefully before answering any chart-based question.
Practice routine
Start untimed until you can explain the pattern. Then switch to timed sets so the skill holds up inside a full module.
- Do 10 warmup questions and write down every mistake type.
- Do 20 timed questions from the same skill.
- Review missed questions without looking at the explanation first.
- Repeat the misses 48 hours later to confirm the fix stuck.
How to use this on real SAT questions
One-Variable Data: Distributions and Measures questions are easiest to improve when you practice the recognition step before the calculation step. First identify the Problem-Solving and Data Analysis pattern, then choose the fastest method.
Inside the bank, start untimed until you can explain why the answer works. Then rerun the same skill under time pressure and review only the misses and guesses.
- Median is resistant to outliers; mean is not.
- Standard deviation increases as data points spread farther from the mean.
- Read the axes and scale carefully before answering any chart-based question.
How to recognize this question type
One-Variable Data: Distributions and Measures questions usually signal themselves through the representation they give you: an equation, table, graph, short passage, or answer-choice pattern tied to Problem-Solving and Data Analysis. Do not start calculating until you have named the pattern.
On a real module, the fastest students first decide whether the question is asking for a value, a relationship, an interpretation, or a rewritten form. That decision tells you which tool to use.
- Look for wording connected to One-variable data: Distributions and measures of center and spread.
- Identify whether the answer should be a number, expression, sentence, or interpretation.
- Underline the exact value or claim the question asks for before touching the answer choices.
- Median is resistant to outliers; mean is not.
- Standard deviation increases as data points spread farther from the mean.
90-minute drill block
Use this sequence when the page is no longer just reading material. The goal is to convert the topic into score movement.
| Time | Work | Success check |
|---|---|---|
| 0-10 min | Read the rules and solve two examples slowly. | You can say why each step is valid. |
| 10-35 min | Do 10 untimed bank questions from this skill. | Misses are caused by content gaps, not rushing. |
| 35-65 min | Do 15 timed questions from the same skill. | Average time stays under the module pace. |
| 65-90 min | Redo every miss without the explanation open. | You can solve the miss cleanly on the second pass. |

FAQs
How do I practice SAT one-variable data: distributions and measures?
Drill one-variable data: distributions and measures as its own skill first, then mix it into timed modules. Isolated practice builds the pattern; timed modules prove you can use it under pressure.
Is one-variable data: distributions and measures important on the Digital SAT?
Yes. It is part of the official Problem-Solving and Data Analysis domain for the SAT Math section, so it can appear on real test forms.
Should I review explanations after every question?
Review every missed or guessed question. Correct guesses still hide weak reasoning, and weak reasoning becomes expensive on hard Module 2.
