Topics in Inferential Statistics

1

Population, Sample, and Sampling Methods

  • Population is the complete group of individuals or objects we want to study
  • Sample is a subset of the population used to make inferences about the entire population
  • Sample size (n) is always smaller than population size (N)
2

Parameters vs Statistics and Central Limit Theorem

  • Parameters describe populations (denoted by Greek letters)
  • Statistics describe samples (denoted by English letters)
  • Central Limit Theorem states that sampling distribution approaches normal distribution as sample size increases
3

Hypothesis Testing Framework

  • Null Hypothesis (H₀) assumes no difference or no effect
  • Alternative Hypothesis (H₁) states there is a difference or effect
  • H₀ uses equality signs (=, ≥, ≤)
4

One Sample t-Test

  • Used when comparing sample mean to known population mean
  • Requires normally distributed population with unknown variance
  • Test statistic follows t-distribution
