One of the characteristics of probability sampling is

The correct option is: Random selection

Important Points

Probability sampling is a sampling technique used in research and statistics, where each member of the population has a known and equal chance of being selected to be part of the sample.

• It is based on the principle of random selection.
• In probability sampling, every individual or element in the population has a non-zero chance of being selected for the sample.
• This ensures that the sample is representative of the entire population and helps reduce bias in the selection process.

 Population bias:

• Population bias refers to the distortion or non-representativeness of the sample due to the characteristics of the population being studied.
• This is not a characteristic of probability sampling.

Sampling bias:

• Sampling bias occurs when some members of the population are more likely to be included in the sample than others, leading to an unrepresentative sample.
• Probability sampling aims to reduce sampling bias through random selection.

 Accidental selection:

• Accidental selection, also known as convenience sampling, is a non-probability sampling method where researchers choose individuals who are readily available or easily accessible.
• It does not involve random selection and may lead to bias in the sample.

Therefore, the correct characteristic of probability sampling is option 3) Random selection.
