Solved assignments library
A searchable library of real homework solutions, solved by hand and checked by editors. Browse 3+ worked problems across statistics and more, each scored for difficulty, mapped to its method, and annotated so you can see exactly how the answer was reached.
These solutions are for learning, not submission. See our honor code for how to use them responsibly.

A worked chi-square goodness-of-fit test on daily coffee sales counts. Sets up the null, computes expected frequencies, calculates the statistic, looks up critical value, and interprets at the 5% level.

The problems our editors return to most. Each solved by hand, mapped to its method, and annotated with the mistakes to avoid.
A worked chi-square goodness-of-fit test on daily coffee sales counts. Sets up the null, computes expected frequencies, calculates the statistic, looks up critical value, and interprets at the 5% level.
Worked solutions for five SPSS-based exercises: paired t-test on advertising campaign effectiveness, Kruskal-Wallis test for teaching assistant performance, independent t-test comparing university grades, one-way ANOVA on social media marketing, and two-way ANOVA examining the beer goggles effect with gender interaction.

Statistics is live and growing weekly. Accounting, economics, and more are being worked now.
Read the approach map first, then work down the steps. The goal is to learn the route from problem to answer, not just the final number.
Every solution flags where students slip: wrong degrees of freedom, mixing up proportions and counts, forgetting to state the conclusion in context.
Rework the problem with your own numbers. Copying a solution defeats the point and breaks academic integrity. See our honor code.
What makes ours different
Real problems worked by hand, with every step, formula, and figure laid out, then annotated by editors so you can see the reasoning, not just the result.

Frequently asked
No. Every solution is written by a human subject expert and reviewed by an editor. We deliberately don't use AI for the math, because students need correct work and AI tools still hallucinate on multi-step computations. Zero AI in the writing.
No. These are reference materials to help you understand the technique, not assignment substitutes. Copying a solution verbatim is academic dishonesty and will fail Turnitin and most proctoring tools. Read our honor code for how to use the library responsibly.
Because the trap is more useful than the answer. A worked solution shows you the right path. A common-mistake note shows you why the wrong path looks correct, which is what students actually fall into. Both together teach you the technique, not just the answer.
They're past homework work shared with us, anonymized, then rewritten and annotated by our editorial team. Identifying details are stripped, problem context may be reframed, and older work is prioritized to minimize overlap with active grading systems.
Yes, free. No signup, no email gate, no paywall. We make money when students hire experts for custom solutions. The library is a marketing surface, and we'd rather you read it freely than wall it off behind a form.
Contact us via our DMCA process and we'll take it down within 24 hours. We try to avoid this with anonymization and rewrites, but if a solution slipped through that you wrote, we'll make it right.
Send us your problem and dataset. A specialist will solve it from scratch, show every step, and have it editor-checked before you see it.
