Detailed explanation-1: -A population is the entire group that you want to draw conclusions about. A sample is the specific group that you will collect data from. The size of the sample is always less than the total size of the population. In research, a population doesn’t always refer to people.
Detailed explanation-2: -Determine the total population of the study. The population will always be the bigger number of the sample size and population. The population is the whole group of people being studied. In the example, the population is the size of the high school being studied, so 250 people.
Detailed explanation-3: -Sample size refers to the number of participants or observations included in a study. This number is usually represented by n. The size of a sample influences two statistical properties: 1) the precision of our estimates and 2) the power of the study to draw conclusions.
Detailed explanation-4: -A population for a research study may comprise groups of people defined in many different ways, for example, coal mine workers in Dhanbad, children exposed to German measles during intrauterine life, or pilgrims traveling to Kumbh Mela at Allahabad.
