To pass StraighterLine Statistics, aim for a minimum overall score of 70, bank easy points on checkpoints and benchmarks, study with short daily retrieval sessions, and use OpenStax for explanations plus targeted drill on weak topics. The current Intro to Statistics course lists twelve benchmarks and one cumulative benchmark, with calculators allowed and an average time to finish of about a month.
What the course expects
- Passing threshold: You need at least 70 percent overall to pass.
- Typical assessment mix: 12 benchmarks plus 1 cumulative benchmark for Intro to Statistics. The course page also notes calculators are allowed.
- Time to finish: Students complete it in about 33 days on average, though you can go faster or slower.
Tip: Policies and formats can change by term. Always confirm the exact assessment list and rules inside your StraighterLine dashboard.
A simple plan that works
1) Make a four week roadmap
- Week 1: Descriptive stats, graphs, and summary measures
- Week 2: Probability, discrete distributions
- Week 3: Normal and t distributions, confidence intervals
- Week 4: Hypothesis testing, correlation and regression
Use the StraighterLine outline as the source of truth, then match modules in a free, college-level text like OpenStax Introductory Statistics for explanations and extra examples.
2) Study with retrieval, not rereads
Do short, daily retrieval practice blocks: closed-book quizlets, two or three end-of-section problems, or one mini mixed set. Retrieval and interleaving across topics beat massed practice for long term learning and transfer.
3) Bank points early
Because your overall grade is a weighted average and the pass mark is 70, treat benchmarks and checkpoints like guaranteed points. Do a quick warmup set from OpenStax, then attempt each item and circle anything that needs a second pass.
4) Use your calculator like a pro
Since calculators are permitted, practice keystrokes for mean, standard deviation, normal cdf, invnorm, linreg, and one-sample or two-sample tests. Build a one page keystroke sheet and rehearse it with mixed problems.
Topic by topic quick wins
Descriptive statistics and graphs
- Be fluent with mean, median, quartiles, standard deviation, and when each summary is appropriate.
- Practice from OpenStax sections on exploring data and frequency tables.
Probability essentials
- Focus on independence, complements, addition and multiplication rules, and basic counting.
- Mix ten problems that force you to decide which rule applies before you compute.
Normal models and z scores
- Memorize the sketch: center, spread, tails, and when to standardize.
- Drill three patterns: area below, area between, and value for a given percentile.
Confidence intervals
- Know the recipe: conditions, statistic, standard error, critical value, and interpret the interval in plain language.
- Alternate mean and proportion cases so you do not lock into one pattern. (OpenStax)
Hypothesis testing
- Write the hypotheses first, decide test type, set alpha, compute the statistic, and finish with a contextual conclusion.
- Keep a tiny “decision tree” card for z or t, one or two samples, and matched pairs.
Correlation and regression
- Correlation measures strength and direction, not causation.
- In the calculator, practice linear regression and learn to explain slope and intercept in the real context.
Quizzes, benchmarks, and your retake strategy
StraighterLine’s current policy gives unlimited attempts on your first exam, then up to three attempts on later exams or quizzes, with your best score counting. Final exams are a single attempt. Use this to front-load practice and secure points before the cumulative.
Game plan: attempt once for scouting, make a list of misses, do a ten-minute retrieval block, then reattempt. Save a clean run for your third attempt.
Practice set that mirrors the course
- 10 daily problems mixing two topics: one descriptive, one inference.
- One weekly cumulative: 12 to 15 items that blend three modules. Interleaving across topics improves memory and problem solving.
