Business analysis is the backbone of smart decision-making, and statistical inference is one of its most powerful tools.
Think of questions like:
➡️ Did the process improvement really bring better results?
➡️ Is one process more reliable than another?
These are the types of challenges that inference helps us solve. And at the center of it all is the Normal Distribution — often called the "queen of distributions."
From the Normal Distribution, we can derive other fundamental tools:
➡️ Student's t-test → compare differences between means
➡️ F Distribution → compare differences between variances
➡️ Chi-square → discover associations between categorical variables
🎥 In the following video, I explain the Normal Distribution in an intuitive way — using the Galton board video as a visual demonstration.
In the upcoming posts, we will intuitively show how to build other distributions from the normal distribution and how to apply them.
Stay tuned!
