A sample in mathematics refers to a small subset or portion of a larger population that is selected for analysis or study. It is often used to make predictions or inferences about the overall population based on the information gathered from the sample.
When collecting data or conducting experiments, it is not always feasible or practical to collect information from the entire population. This is where sampling comes in – by selecting a representative sample, we can make inferences about the entire population with a certain level of confidence.
For example, let’s say you want to know the average height of all students in a school. Instead of measuring the height of every single student, you can randomly select a sample of, let’s say, 100 students. By measuring the height of these 100 students and calculating their average height, you can then use this information to estimate the average height of all students in the school.
However, it is important to note that the accuracy of the estimates derived from a sample depends on the sampling method used, the size of the sample, and the variability within the population. Statistical techniques are often employed to ensure that the sample is representative and that the estimates derived from it are reliable.
In summary, a sample in mathematics is a subset of a larger population that is selected for analysis, and it is used to make predictions or inferences about the entire population.
