    Chapter Journey: Sampling Distributions and Estimator Properties

    1
    Sampling Distributions and Chi-Square Results (Current Topic)
    Distribution of , Chi-Square definition, Sample Variance Identity.
    2
    Estimator Bias and Variance Properties
    Bias, MSE, Unbiasedness, Consistency, and Efficiency.
    Exam Weightage Hint: Both topics are foundational for Hypothesis Testing and Confidence Intervals. Expect questions that test your ability to identify the correct distribution of a given statistic and to prove unbiasedness using these distributions.

    Hero Concept: What is a Sampling Distribution?

    What is a Sampling Distribution?

    A statistic is any function of the sample data that does not depend on unknown parameters. Examples include the sample mean , sample variance , and sample proportion .

    Because the sample data is random, the statistic itself is a random variable. The probability distribution of this random variable is called its sampling distribution.

    Why It Matters
    To make inferences about a population, we must know how our statistic behaves across all possible samples. The sampling distribution provides the exact mathematical model for this behavior.
