*Margin of Error Calculator* is an online Probability and Statistics tool for data analysis programmed to determine the amount of random sampling error in a survey's results. This calculator generate the output value margin of error according to the respective input values of sample size, probability and population size

### Definition

The **margin of error** is a widespread abstract of sampling error, which measures an uncertainty about an experiment or test result. The margin of error can be understood by making use of ideas from the laws of probability. Experiments are often performed by starting out with a list as known as the sampling frame of all units in the population and choosing a sample. In scientific experiments, every unit in the population has some known positive probability of being selected for the sample, and the probability of any particular sample being chosen can be calculated. The larger the margin of error, the less faith one should have that the poll's reported results are close to the true figures; that is, the figures for the whole population. Margin of error arises whenever a population is incompletely sampled

The collection of tools employs the study of methods and procedures used for gathering, organizing, and analyzing data to understand theory of Probability and Statistics. The set of ideas which is intended to offer the way for making scientific implication from such resulting summarized data. In many applications it is necessary to calculate the margin of error where this online margin of error calculator can help you to effortlessly make your calculations for the respective inputs
