A population is a finite or infinite group of people, objects, or animals that have certain characteristics in common. Examples of populations are a particular group of horses, a pack of wolves, or the population of a city.
The populations are studied in order to reach conclusions; They are usually delimited in an area to be able to make statistics on them. For example, the population of the country of Colombia can be used to know if there are more women or men, or to know how many children there are.
Horse population
A population sample refers to a significant representation of all the characteristics of a given population.
Many studies or important work can be done; For this reason, samples from a population are usually studied and the entire population is not used as it would involve much more work.
When experts speak of population, they are not necessarily referring to living things. Statistics can refer to a population of objects, events, observations, or procedures.
This can include things like the amount of lead in the urine, doctor visits, surgical operations, etc.
Although the population can be clearly defined, sometimes it is not possible to list them correctly. For example, "the population of the Earth" can be used and is understood to be the number of people within the limits of the planet listed with a census.
However, a doctor could study the question "what is the average blood pressure of the English between 40-45 years?"; But not all English live in England, and their socio-economic profiles vary.
That is why statistics that are taken from a population, such as averages and standard deviations, are referred to as population parameters.
