Course Overview¶
- Institution: MIT
- Course code: 18.05
- Track: Probability, Statistics, and Random Processes
- Tier: S
- Role: Alternative

- Last reviewed: 2026-07-28
MIT's Introduction to Probability and Statistics offers a computational entry to probability and statistics, combining notes, practice, exams, R activities, and interactive questions without lecture videos.
Why choose this course
Alternative course. A particularly complete and well-structured option for this track.
Before you start
- Recommended foundation: Engineering Mathematics
Verifiable learning outcomes
- Explain the core models in Probability, Statistics, and Random Processes, including their assumptions and limits
- Solve representative derivations and problems, checking units, limiting cases, or numerical results
- Complete a reproducible experiment or implementation with raw data, parameters, versions, and verification
Workload and pacing
11 weeks at 9 hours/week. This maintainer planning estimate is derived from course role and the density of public practice and labs; it is not a provider workload promise. Pilot two weeks while logging instruction, practice, lab, and review time, then adjust the remaining plan when actual effort differs by more than 25%.
Safety level
Simulation only. The default practice scope is software, computation, or simulation only; a lab label in the resource inventory does not authorize connecting physical equipment, and any hardware extension requires provider-scope verification and a new risk assessment.
Course Resources¶
Software, hardware, and cost
Software
- Maintainer-suggested open-source/free verification path: Python 3, Jupyter, NumPy, SciPy, pandas, statsmodels, and Matplotlib
- The resource inventory lists public code coverage; pin interpreter, dependencies, toolchain, datasets, and PDK versions where applicable
Hardware
- The resource inventory lists lab coverage; the maintainer path treats it as computational/simulation work unless the provider lab manual explicitly says otherwise. It assumes only a general-purpose computer that can rerun statistical notebooks and retain data snapshots; no dedicated physical hardware is assumed. If the provider lists different equipment or compute requirements, follow its course page
Cost note
The suggested software stack is available open source or free; this is maintainer planning, not a provider requirement. If the provider specifies commercial licenses, cloud compute, storage, or institutional resources, costs vary by plan, region, and institution, so no fixed price is asserted here.

Practice and Verification¶
Practice loop
Introduction to Probability and Statistics · MIT 18.05: Stochastic Estimator Calibration and Failure Study
This is a maintainer-suggested self-study project for Introduction to Probability and Statistics · MIT 18.05, not an official course assignment. Build a controlled stochastic data generator and estimator for Probability, Statistics, and Random Processes, then test bias, variance, interval coverage, and robustness under distribution shift.
Origin: Maintainer-suggested project
Deliverables
- A synthetic-data generator with an explicit probability model, ground-truth parameters, and independent random seeds
- Source code and complexity notes for at least one baseline estimator and one improved estimator
- Raw samples, estimates, confidence intervals, and summaries from at least 1,000 repeated trials
- A report comparing bias, RMSE, and coverage and analyzing failure under small samples, heavy tails, or correlated noise
Verification
- Under the nominal distribution, keep relative bias below 2% across 1,000 trials or explain the theoretical bias
- Obtain empirical coverage between 92% and 98% for a nominal 95% interval
- Cross-check mean, variance, and at least three quantiles analytically or with a second statistics library
- Replace nominal noise with heavy-tailed or correlated noise and quantify RMSE and coverage degradation from baseline
Reproducibility
- Commit versioned generator, estimator, test, and plotting sources with a README
- Pin the environment, dependencies, RNG algorithm, and every seed and provide one-command batch execution
- Preserve per-trial raw data with checksums and rebuild the report automatically from that data
Safety boundary: Simulation only — Use synthetic data only; do not apply exercise-derived conclusions to real people, clinical decisions, or safety-critical prediction.
Risks, gaps, and boundaries
No lecture videos; the free MIT Open Learning Library version supplies interactive questions and R activities.
Completion evidence
- Weekly learning log with time, questions, corrected errors, decisions, next steps, and links to that week's reproducible artifacts
- Theory dossier with explicit assumptions, notation, derivation, units, and boundary conditions, checked by at least one independent method
- Simulation package with model or netlist, inputs, solver and version, parameter-sweep script, benchmark comparison, expected results, and one rerun command
- Code repository with pinned dependencies and toolchain, a minimal run command, tests or waveform/benchmark checks, expected output, and license notes
