In the mind of a statistician, the world consists of populations and samples.

This article will cover the basic statistical functions of mean, median, mode, standard deviation of the mean, weighted averages and standard deviations, correlation coefficients, z-scores, and p-values.

Statistical methods can be used to determine how reliable and reproducible the temperature measurements are, how much the temperature varies within the data set, what future temperatures of the tank may be, and how confident the engineer can be in the temperature measurements made. For example, a chemical engineer may wish to analyze temperature measurements from a mixing tank. Statistics is important in the field of engineering by it provides tools to analyze collected data. Midpoint between the lowest and highest value of the set (median).Span of values over which your data set occurs (range), and.On average, how much each measurement deviates from the mean (standard deviation of the mean).A few examples of statistical information we can calculate are: Statistical methods and equations can be applied to a data set in order to analyze and interpret results, explain variations in the data, or predict future data. Statistics is a field of mathematics that pertains to data analysis.
