"A population is any entire collection of people, animals, plants or things from which we may collect data. It is the entire group we are interested in, which we wish to describe or draw conclusions about.
In order to make any generalizations about a population, a sample, that is meant to be representative of the population, is often studied. For each population there are many possible samples. A sample statistic gives information about a corresponding population parameter. For example, the sample mean for a set of data would give information about the overall population mean.
It is important that the investigator carefully and completely defines the population before collecting the sample, including a description of the members to be included."
"The population for a study of infant health might be all children born in the UK in the 1980's. The sample might be all babies born on 7th May in any of the years."

Population is the selected grouping of people or anything else in that manner where we retrieve and gather information, knowledge, and data from. We can select a sample amount from the population and use the information gathered to imply and conclude about that population. The sample can either be randomly chosen, or selected. There can be many samples in a population so the sample should always be specific when inputting your information.
