We often hear companies advertise dandruff shampoos that they claim are 100% effective, are these results realistically possible?

Hypothesis tests give a way of using samples to test whether statistical claims are likely to be true or not about a population.

What is Hypothesis Testing?

Why is it done?


An introduction to Decision trees — a Machine Learning algorithm used as a foundation for complex ensemble techniques.

Decision Tree is a supervised learning algorithm used for predictive modeling and solving CART — classification and regression problems. It generates a tree in the form of simple ‘if-then’ rules where each node represents a feature(attribute), each link(branch) represents a decision(rule) and each leaf represents an outcome(categorical or continuous value).

It is used as a foundation for many classical machine learning algorithms like Random Forest, Bagging, and Boosted Decision Trees.

Geometrically, the ‘if-then’ rules are axis parallel cuts forming rectangles in 2D…
