Numerical descriptive measures computed from data are called statistics. numerical descriptive measures of the population are called parameters. inferential statistics can be used to generalize the findings from sample data to a broader population. completing this unit should take you approximately 22 hours. And maybe that guy would come and say, well, you know, actually, the probability that i get a 1 is 1/6 plus 0.001 and the probability that i get a 2 is 1/6 minus 0.005. and there would be some fluctuations around this.

Introduction to statistics. what is statistics? statistics is a mathematical science including methods of collecting, organizing and analyzing data in such a way that meaningful conclusions can be drawn from them. in general, its investigations and analyses fall into two broad categories called descriptive and inferential statistics. Statistics include numerical facts and figures, but also involves math and relies upon calculations of numbers. it also relies heavily on how the numbers are chosen and how the statistics are interpreted. 1.2: importance of statistics it is important to properly evaluate data and claims that bombard us every day.
