This course offers an in-depth exploration of various sampling techniques and their applications in statistics. Students will learn about both random and non-random sampling methods, understanding their advantages, limitations, and appropriate use cases. Key topics include:

1. Introduction to Sampling
   • Importance and role of sampling in statistics.
2. Random Sampling Techniques
   • Snowball Sampling: Gathering samples through referrals.
   • Voluntary Sampling: Participants opt-in voluntarily.
   • Simple Random Sampling: Equal chance for each member.
   • Systematic Sampling: Selecting every nth member.
   • Stratified Sampling: Dividing population into subgroups and sampling from each.
   • Cluster Sampling: Dividing population into clusters and sampling whole clusters.
3. Non-Random Sampling Techniques
   • Convenience Sampling: Using readily available samples.
   • Purposive Sampling: Selecting samples based on specific criteria.
   • Quota Sampling: Ensuring sample represents certain characteristics.
   • Judgment Sampling: Expert selection based on judgment.
4. Frequency Distribution and Graphs
   • Constructing and interpreting frequency tables.
   • Visual representation using histograms, bar charts, pie charts, and frequency polygons.

By the end of the course, students will be skilled in selecting appropriate sampling methods for various research contexts and presenting data visually to facilitate better understanding and decision-making.
