        • How It Works

      • Sampling: Selecting a representative sample from the population.

        • Statistical inference involves drawing conclusions about a population based on a sample of data. It uses mathematical techniques to determine the likelihood of a hypothesis being true. Here's a simplified explanation:

        1. Misinterpretation: Incorrectly interpreting the results can lead to flawed conclusions.
        2. Sampling Errors: The sample may not accurately represent the population, leading to incorrect conclusions.
