Give reason or explain

3) There is a possibility of bias element in deliberate sampling.

Answer 1

1. Under the census method of survey, every item of a population is taken into account. That is, the information is collected from every single element of the population. In such case, each unit of the universe is studied. Therefore, we can say that this method of data collection is more accurate in nature as it takes into account the whole population and not just samples.

2. Primary data refers to the data collected by an investigator himself to carry out a specific research. Such data is collected by the investigator for the first time from the original source of information. Thus, primary data is first-hand information or original raw data that can be further used by others.

3. Deliberate sampling is a type of sampling in which the investigator picks out the samples based on his choice. This selection process depends on the judgement or personal choice of the investigator therefore, it involves the possibility of bias.
