Study.com’s Statistics 101 starts easy and gets hard fast — FMMC helps students through the chapters that matter most.

Quick Answer

Statistics 101: Principles of Statistics (SDCM-0068) is a 3-credit, ACE-recommended Study.com course covering descriptive statistics, probability, distributions, sampling, regression, and hypothesis testing across 10 chapters. There are no assignments — grading is 100 points from chapter tests and 200 points from the final exam. All assessments are open-book and unproctored. No prerequisites are required.

What Statistics 101 Covers

Study.com’s Statistics 101 is a standard introductory statistics course accepted at over 2,000 colleges and universities for lower-division credit. It satisfies general education math requirements at most institutions and serves as a prerequisite for upper-level courses in business, psychology, nursing, and the social sciences.

The course runs 10 content chapters. Each chapter ends with a 15-question chapter test — open-book, up to 3 attempts, highest score counts. Chapter tests account for 100 of the 300 total points. The remaining 200 points come from the 50-question cumulative final exam.

Chapter Topics Difficulty
Ch 1: Overview of Statistics Data types, variables, populations vs. samples, study design Low
Ch 2: Summarizing Data Mean, median, mode, standard deviation, variance, IQR Low
Ch 3: Tables and Plots Histograms, stem-and-leaf, box plots, two-way tables, bar graphs Low
Ch 4: Probability Set theory, conditional probability, independence, counting rules Medium
Ch 5: Discrete Distributions Binomial distribution, Poisson distribution, expected value High
Ch 6: Continuous Distributions Normal distribution, z-scores, standard normal curve, exponential High
Ch 7: Sampling Sampling methods, central limit theorem, sampling distributions Medium
Ch 8: Regression & Correlation Scatter plots, correlation coefficient, linear regression, residuals Medium
Ch 9: Statistical Estimation Confidence intervals, margin of error, sample size calculations High
Ch 10: Hypothesis Testing t-tests, z-tests, matched pairs, proportions, p-values, Type I/II errors High

Where Students Get Stuck

The first three chapters feel manageable. Mean, median, mode, reading a histogram — students move through these quickly and assume the rest will follow the same pattern. It does not.

Chapter 4 (Probability) is where the course shifts from reading and interpreting to actual calculation. Conditional probability and set theory require a different kind of thinking, and students who rush through the videos without working problems often burn two of their three chapter test attempts here.

Chapters 5 and 6 are the hardest back-to-back pair in the course. Discrete distributions require recognizing when to apply binomial versus Poisson formulas. Continuous distributions introduce z-scores and the normal curve — concepts that appear in every chapter that follows. A weak score on Chapters 5 or 6 creates compounding problems through Chapters 7 to 10.

Chapters 9 and 10 are where the final exam is won or lost. Confidence intervals and hypothesis testing are both procedural and conceptual — students need to know which test applies to which situation. The final will test this directly: matched pairs versus independent samples, z-test versus t-test, one-tailed versus two-tailed. Students who memorized steps without understanding the logic cannot navigate these reliably under time pressure.

The grading math: score 55% on Chapters 5 and 6, and you enter the final needing 165 out of 200 points just to reach 210 total. That is an 82.5% on a 50-question cumulative exam — not the comfortable position most students imagine they are in.

Frequently Asked Questions

Is there a prerequisite for Study.com Statistics 101?

No. Study.com lists no prerequisites for Statistics 101. The course does assume basic algebra — working with formulas, solving for variables, reading graphs — but does not require prior statistics or calculus experience. Study.com’s own course page recommends completing Math 101: College Algebra first if your algebra skills are rusty.

Does Statistics 101 include assignments or just exams?

Just exams. Statistics 101 has no written assignments or projects. The full 300 points come from chapter tests (100 pts) and the final exam (200 pts). This means your final exam score carries significant weight — you need at least 70% overall, and a weak chapter test average forces a higher bar on the final.

Which chapters on the Statistics 101 final exam carry the most weight?

The 50-question final is cumulative, but Chapters 9 and 10 — confidence intervals and hypothesis testing — carry the most questions because they draw on nearly everything covered earlier. Students who are solid on z-scores and distributions (Chapters 6 and 7) will find those chapters much more manageable. Rushing to the final without mastering those foundations is the most common reason students fail the first attempt.

Can I use a calculator on the Statistics 101 final exam?

Yes. The final exam is open-book and open-note with no browser locking. Students can use a calculator and refer to course materials during the exam. The challenge is not access to resources — it is knowing which formula applies to which problem under time pressure. The 2-hour limit on a 50-question cumulative exam does not leave much time for working from first principles on unfamiliar question types.

How many credits does Statistics 101 transfer for?

Statistics 101 carries an ACE recommendation for 3 semester hours of lower-division credit. Most colleges accept this for general education math requirements. Transfer credit is not guaranteed at every institution — check with your registrar or confirm with your advisor before enrolling. Study.com’s partner college list is a useful starting point, but students at non-partner schools should contact their institution directly.

Do I need to complete all 10 chapters before I can take the final exam?

Yes. Study.com requires all chapter tests to be completed before the final exam unlocks. You cannot skip chapters or take the final early. This matters because chapter test scores are locked in before you sit down for the final — if you rushed through Chapters 5 or 6 and scored poorly, those points cannot be recovered later. Students who treat the chapter tests as a warmup and save their effort for the final often find themselves in a much harder position than expected when the exam opens.

I already failed one final exam attempt. Can FMMC still help?

Yes — as long as you have remaining attempts. You have three total, with a 3-day wait between each. If you have used one or two attempts, contact FMMC immediately. The 3-day window is enough time to identify exactly where the points were lost and prepare specifically for those question types before your next attempt.

Does FMMC help with other Study.com courses besides Statistics 101?

Yes. FMMC works across Study.com’s full catalog. See the Study.com Help hub for the full list of supported courses including Math 101, Chemistry 101, Physics 101, Discrete Mathematics, and more.
