SAMPLING TECHNIQUES IN RESEARCH

 1. RANDOM SAMPLING

 It is a type of probability sampling where by every individual has an equal chance to be selected in a sample. This technique involves selecting a sample randomly from the sampling frame without replacement. E.g. it is very common in Lottery’s such as Bingo and communication companies.

SAMPLING TECHNIQUES IN RESEARCH

Disadvantages

- The better sample may not be chosen.

- It is very tedious or tiresome.

- It is time consuming especially when the population is high.

- It is representative in Heterogeneous population. Heterogeneous population –means a population with different characteristics.

2. SYSTEMATIC SAMPLING

 It is a sampling technique where by a sample is obtained randomly but in a systematic way. It is a sampling technique which involves selection of a sample randomly at regular intervals from the sampling frame

3. STRATIFIED SAMPLING

 -Individuals for the sample are selected from different strata. Example: A researchers wishes to get a sample of 20 students from 5 schools he/she will have to select 4 students from each.

4. PURPOSIVE SAMPLING:

 Is the judgemental sampling in which a researcher uses his/her knowledge to choose individuals to be samples. The sample base on certain purpose e.g only engineer, male, students, youth,elders,etc

 5. ACCIDENTAL SAMPLING

 –The researcher comes into contact accidentally with the individuals to form a sample.

6. SNOW BALL SAMPLING

 - The researcher begins with the few individuals available, then those individual recommend others. The uses of research outputs and recommendations

1. Help to improve the knowledge of the people e.g Discovery of diseases.

2. The results help in finding problems facing society e.g Diseases, social inequalities, famine.

3. The results improve economic and social activities e.g Introduction of new breeds of cattle.

4. Research can lead to exploitation of the new resources like minerals and fossil fuel.

5. It helps to identify the specific need of each community e.g Community A needs schools, Community B needs water, etc.

6. Research results are useful in protecting and concerning the environment.

7. They are used in formulating government policy
