Answer: In statistics, n represents the sample size, or the number of observations or data points in a sample.
The sample size, denoted as n, is crucial in statistical analyses because it impacts the precision of statistical estimates and the power of hypothesis tests. The value of n determines the level of detail and accuracy that can be obtained from the sample about the population from which it was drawn. For example, in a study measuring the heights of adult men in a city, if 100 men are measured, then n=100.
Calculating n involves simply counting the number of observations in the dataset. For instance, if you conduct a survey with 50 respondents, then n = 50.
In conclusion, n is a fundamental concept in statistics that represents the number of observations in a sample.
