Answer

  1. Investigator: The person or agency who is conducting the statistical enquiry is called investigator.
  2. Population: The people about whom investigator is collecting data are a part of his enquiry's population. For example, if we wish to conduct a survey on usage of baby products, then mothers who have a baby in the age group of 0-5 are a part of our population. Similarly, if a teacher wants to know average height of his class, then students in his class constitute her population.
  3. Respondent: The person from whom the investigator is collecting statistical information is called respondent.
