Statistical concept that larger the sample population (or the number of observations) used in a test, the more accurate the predictions of the behavior of that sample, and smaller the expected deviation in comparisons of outcomes.
There is no sampling method that will select the exact population.
The only way to get rid of sampling error is to use the entire population under study. This is usually impossible, so the next best thing is to use large samples and good sampling methods.
a simple random sampling is very difficult to conduct if the size of the population being studied is large. Moreover , it needs a lot of time and money. - S
The four main types of sampling techniques are: Random Sampling: Every member of the population has an equal chance of being selected, ensuring unbiased representation. Stratified Sampling: The population is divided into subgroups (strata) based on shared characteristics, and random samples are taken from each stratum to ensure representation across key segments. Systematic Sampling: Members are selected at regular intervals from a randomly ordered list, such as every nth individual. Cluster Sampling: The population is divided into clusters, often geographically, and entire clusters are randomly selected, which can be more practical for large populations.

Researchers are using a procedure known as simple random sampling. This involves selecting individuals at random, where every individual has an equal chance of being selected, to ensure the sample is representative of the population.

you can use sampling when your population under study is large, expensive and time time consuming to study.... in a nut shell, when studying entire population is expensive we go for sampling...

Ideally, representative samples should be: Taken at random so that every member of the population of data has an equal chance of selection; Large enough to give sufficient precision; Unbiased by the sampling procedure or equipment.
Conch poisoning affects people who consume raw conch, which has been contaminated by large numbers of bacteria. Hope this helps!!!:D

Obviously "large numbers"
its time consuming and expensive if its a large sample you need or a big target population
sampling in a large area or tagging in a smaller area
