Question and answer
Explain how populations and variables differ?
a population is the collection of individuals or objects of interest. These individuals or objects may be referred to as members or units of the population. [ If we are able to record all desired information on each unit in the population, then we have taken a census. The problem is that we rarely have the ability to gather the information from every unit of the population, due to financial
constraints, time limitations, or some other reasonA variable is a characteristic that may be recorded for each unit in the population, and the observed value of the variable is generally not the same for all units. The length, weight, age, gender, and mercury level of the fish are five variables, some or all of which might be of interest in a particular study. ]
