NON-PROBABILITY SAMPLING DESIGNS

 

INTRODUCTION:  These do not follow the theory of probability in the selection of elements from the sampling population. Non-probability sampling designs are used when the number of elements in a population is either unknown or cannot be individually identified. In such situations the selection of elements is dependent upon other considerations. Non-probability sampling designs are commonly used in both quantitative and qualitative research.  

CATEGORIES OF NON PROBABILITY SAMPLING DESIGNS:  Some of the categories in non probability sampling include; 

1.  Convenience sampling 

2.  Judgement sampling

3.  Quota sampling and

4.  Snowball sampling
