    Data Analysis · Interactive Case Studies

    Statistics make decisions safer

    Discover how statistical analyses can move your business forward — with real examples you can explore yourself.

    📊

    Descriptive Statistics

    Key metrics & distributions — the first look at your data

    Retail & E-Commerce
    Use case: An online shop analyses its daily orders over the last quarter. Mean, variance and skewness help steer inventory, staffing and ad campaigns with data.

    Inferential Statistics — Two-sample t-test (Welch)

    From sample to validated statement about the population

    Production & Quality
    Use case: A food manufacturer tests two production lines. Line A (control) vs. Line B (new recipe). Is the difference in package weight statistically significant — or just chance?

    Exploratory Data Analysis — K-Means Clustering

    Automatically identify hidden customer segments

    Marketing & CRM
    Use case: A fitness studio segments its members by visit frequency and monthly spending — without any prior knowledge. Clusters emerge automatically and enable targeted offers for each segment.

    Causal Analysis — Linear Regression (OLS)

    Measure cause-and-effect relationships and validate them statistically

    HR & Production
    Use case: A plant manager asks: Do more training hours actually reduce the error rate? OLS regression quantifies the effect — and uses t-test and R² to check whether the relationship is statistically robust.

    Predictive Analysis — Time Series Forecast (Holt-Winters)

    Energy & Finance
    Use case: An energy provider forecasts monthly electricity consumption for the coming months — the Holt-Winters model accounts for trend, seasonality and provides prediction intervals for planning certainty.
