📊Types of Sampling Techniques

---

🔍 What is Sampling Technique?

A sampling technique is the method or process by which the researcher selects a portion (sample) from a larger population to participate in a study.

The goal is to choose a sample that is:

• Representative
• Reliable
• Free from bias

Sampling techniques are broadly classified into two categories:

1. Probability Sampling
2. Non-Probability Sampling

---

🧪 1. Probability Sampling Techniques

In this method, every element of the population has a known and equal chance of being selected. It is more scientific, objective, and generalizable.

---

✅ a. Simple Random Sampling

• Every member of the population has an equal chance of being selected.
• Done using lottery method, random number table, or software.

🧠 Example: Drawing names of 50 nurses randomly from a list of 200 staff nurses.

---

✅ b. Systematic Sampling

• Selects every kth element from a population list after a random start.
• Formula: k = Population size / Desired sample size

🧠 Example: From a list of 1,000 patients, selecting every 10th patient to get a sample of 100.

---

✅ c. Stratified Random Sampling

• Population is divided into strata (subgroups) based on characteristics (e.g., age, gender), and random samples are drawn from each stratum.

🧠 Example: Dividing nurses into male and female groups, then selecting 25 randomly from each group.

---

✅ d. Cluster Sampling

• The population is divided into clusters (groups), some of which are randomly selected. Then, either all members in selected clusters or random members are studied.

🧠 Example: Selecting 3 hospitals randomly from a city and studying all nurses in those hospitals.

---

⚠️ Advantages of Probability Sampling

✅ Strengths
More accurate and representative
Allows generalization to population
Reduces selection bias

---

🚫 Limitations

❌ Challenges
Time-consuming and expensive
Needs complete list of population (sampling frame)

---

📋 2. Non-Probability Sampling Techniques

In this method, not every individual has an equal chance of being selected. It is subjective and used when probability sampling is not feasible.

---

✅ a. Convenience Sampling

• Selecting participants who are easily available or willing to participate.

🧠 Example: Interviewing 30 patients who visit the outpatient department during the week.

---

✅ b. Purposive Sampling (Judgmental Sampling)

• Participants are deliberately chosen based on specific characteristics or purpose of the study.

🧠 Example: Choosing only diabetic patients who have been on insulin therapy for more than 5 years.

---

✅ c. Snowball Sampling

• Existing participants refer or recruit future participants from their network.
• Used for hard-to-reach populations.

🧠 Example: Studying drug addiction where one participant leads the researcher to others.

---

✅ d. Quota Sampling

• The researcher divides the population into categories and selects a set quota from each (like stratified, but not randomly).

🧠 Example: Interviewing 40 male and 60 female nurses, selected by convenience, to complete the gender quota.

---

✅ e. Theoretical Sampling (Used in qualitative research)

• Selection continues based on emerging data and concepts until theoretical saturation is reached.

🧠 Example: In grounded theory, interviewing more nurses until no new themes arise.

---

✅ Comparison Table: Probability vs Non-Probability Sampling

Feature	Probability Sampling	Non-Probability Sampling
Selection	Random	Non-random
Bias	Low	High
Generalizability	High	Limited
Cost & Time	High	Low
Use	Quantitative studies	Qualitative or pilot studies

---

🧠 Example in Nursing Research

Study Title: “A study to assess the knowledge of antenatal care among pregnant women in urban slums.”

• If researcher selects a random sample of pregnant women from health records → Probability Sampling
• If researcher interviews women visiting a specific clinic during the week → Convenience Sampling
