Understanding Hypothesis Testing 🐸

What is Hypothesis Testing?

Hypothesis testing is a statistical method used to make decisions about the properties of a population based on sample data. 🧐 It involves setting up two competing hypotheses: the null hypothesis (H0) and the alternative hypothesis (Ha).

The Process of Hypothesis Testing

  1. Formulate the Hypotheses: Start by defining your null and alternative hypotheses.
  2. Choose a Significance Level (α): Common values are 0.05 or 0.01.
  3. Collect and Analyze Data: Execute experiments or surveys to gather data.
  4. Compute Test Statistics: Use appropriate statistical tests to analyze the data.
  5. Make a Decision: Based on test results, either reject H0 or fail to reject it.

Why Hypothesis Testing Matters

Hypothesis testing allows researchers and decision-makers to make informed decisions by providing a framework to evaluate claims about a population. 🌟 This technique is widely used in finance, medicine, psychology, and many other fields.
