Interactive course tools

Make the abstract visible.

Explore optimization, probability, regression, and sampling with purpose-built tools that turn formulas into experiments you can see, change, and discuss.

Four tools. Two disciplines. One place to experiment.

Every tool opens directly in your browser. Nothing to install, no account required, and each module includes a ready-to-use starting example.

Operations Analysis

Decisions under constraints

Build a model, see its geometry, and test how the best decision changes.

Business Statistics

Patterns inside variation

Move from a single observation to probability, relationships, and repeated samples.

Live tool BUS-2150

02 / Probability

Normal Area Explorer

Drag z-score cutoffs and watch shaded probability regions respond across left, right, between, and two-tail questions.

Live tool BUS-2150

03 / Relationships

Linear Regression Studio

Build datasets, compare your line with least squares, and inspect residual, ANOVA, extrapolation, and variance diagnostics.

Live tool BUS-2150

04 / Simulation

Sampling Distribution Explorer

Draw unusual populations, follow individual samples, and watch the distribution of sample means take shape through repeated simulation.

A simple rhythm

Try it before you formalize it.

  2. 02Change Move one input and predict the result.
  3. 03Observe Compare the visual and numerical evidence.
  4. 04Explain Put the pattern into your own words.
