population since it will take too much time and will be expensive as well. So the researchers take few individuals from the research population ( a subset of the set of target population) using sampling techniques. These techniques helps to take out sample as per the requirements of the type of research that is to be conducted. A research population is also known as a well-defined collection of individuals or objects known to have similar characteristics. All individuals or objects within a certain

Simple Random Sampling is done when every individual subject in the population has an equal chance of being selected for the sample, without any bias (Explorable). For example, if a researcher wants to represent the population as a whole, they can pick random numbers or names out a hat or use a program to randomly choose names so the information is not biased. Stratified Sampling is performed by, dividing the population into at least two (or more) groups or sections, which share certain characteristics

Convenience sample- is a non-probability sampling technique where subjects are selected because of their convenient accessibility and proximity to the researcher. Probability/nonprobability-Probability sampling, or random sampling, is a sampling technique in which the probability of getting any particular sample may be calculated. Nonprobability sampling does not meet this criterion and should be used with caution. Nonprobability sampling techniques cannot be used to infer from the sample to the general

sampling assumes two- stage cluster sample design in the year 2013. The stratified two-stage cluster sample design presumes two stages. In the first stage the list of schools are stratified in accordance to the importance of the demographic variables, accompanied by replacement schools in case the targeted fails to participate. Then followed by of more intact class of the target or the participating school. This is in attempt to produce a representative sample of public and private school of students
