Determine, whether the data set, is a population or a sample, explain the number of floors in each home in a town
a. population, because it is a collection of a number of floors for all homes in a town
b. population, because it is a subset of all homes in a town
c. sample, because it is a collection of the number of floors in some of the homes
d. sample, because it is a collection of the number of floors for all homes in the town, but there are homes in other towns
A population is a collection of all the elements available for a study. For example in a study for average salary of people living in a certain city. Population in this case would be the salary figures of every person living in that city.
A sample on the other hand is a subset derived from the population to estimate the characteristics of the population.A sample of say 10000 people was selected and the salary figures of those are recorded.
According to question, the data set is the number of floors in each home in a town. Since it includes number of floors of all the houses in the entire town, this is an example of population data.
Hence, option a is correct.
