Sampling

A process of selecting a subset of individuals from a larger population to represent the whole group in a study.

Simple Random Sampling

A sampling method where each individual in the population has an equal chance of being selected.

Stratified Sampling

A sampling method where the population is divided into subgroups based on certain characteristics and a random sample is drawn from each subgroup.

Systematic Sampling

A sampling method where individuals are selected at regular intervals from a list.

Study Notes

Introduction to Two Sampling Methods

  • The paper investigates two distinct sampling methods, focusing on their comparative strengths and weaknesses in specific situations.
  • Methodologies, assumptions, and intended applications of the methods will likely differ.
  • The study aims to guide researchers in selecting the best method for their data and research question.

Description of Sampling Methods

  • Procedures for each sampling method will be detailed.
  • Descriptions of the target population, sampling frame, and chosen technique (e.g., simple random, stratified, systematic, cluster) will be included.
  • Key features of each sampling procedure will be outlined.
  • Criteria for sample size determination in various scenarios will be presented for each method.

Methodology

  • The paper will likely use a simulated or empirical dataset for analysis.
  • Comparisons of sample statistics (e.g., means, proportions) across the two methods will be made.
  • Confidence intervals and margins of error for each method's estimates will be explored.

Key Comparisons

  • Statistical properties such as bias, variance, and efficiency will be compared between the two methods.
  • Potential limitations in practical application will be discussed for each method.
  • Simulation results will likely demonstrate the methods' performance under various conditions.

Practical Implications and Recommendations

  • Specific situations where one method outperforms the other will be detailed.
  • Optimal sampling methods for specific data characteristics will be recommended.
  • Researchers will receive guidance on collecting and analysing data.
  • Assumptions of the methods and their effects on outcomes will be analysed.
