The distinction between a population together with its parameters and a sample together with its statistics is a fundamental concept in inferential statistics. The main advantage of statistics is that information is presented in an easy way. 10:43. Statistics can be a powerful tool when performing the art of Data Science (DS). So, in some cases, it’s impossible to consider each element. Statisticians try to interpret and communicate the results to others. – any characteristic possessed by a set of objects (e.g., people) of interest, but that only has one value, or otherwise believe that might affect other variables. View 1. What is Data? 0000001172 00000 n Some consider statistics to be a distinct mathematical science rather than a branch of mathematics. 1.

From a high-level view, statistics is the use of mathematics to perform technical analysis of data. Inferential statistics can be used to generalize the findings from sample data to a broader population. In many cases this will be all the information required for a research report.
