mean - approximating the statistical norm or average or expected value; "the average income in New England is below that of the nation"; "of average height for his age"; "the mean annual rainfall" average statistics - a branch of applied mathematics concerned with the collection and interpreta...
Average or mean is useful almost daily and for many reasons, especially in the capital market, science, statistics, etc. Using the appropriate average is the key. This matter is based upon an understanding of the data. The geometric average considers compounding, whereas the arithmetic average co...

The sample mean is useful because it allows us to estimate what the whole population is doing without surveying everyone. In statistics, samples and populations have different meanings. These differences are very important, even if, as in the case of the mean, they are calculated in the same ...
Confidence intervals demonstrate how sure researchers are that a mean will lie between two numbers. Identify the importance of point and interval estimates, confident levels and coefficients, and terms associated with confidence in statistics. Related...

In Elementary Statistics and Probability Theory, the little number next to a variable, say the i inXirepresents the i-th position of said variable. These types of subscripts are commonly seen when working with summation notation and is seen in the following form ...
When teaching statistics we often resort to several notions of mean, such as arithmetic mean, geometric mean, and harmonic mean, and hence the student is often left with the question: The word mean appears in all such concepts, so what is actually a mean? I revisit Kolmogorov's axiomatic ...
