Module 2 Descriptive Statistics Numerical Measurement Pdf Module 2 descriptive statistics numerical measurement (1) free download as pdf file (.pdf), text file (.txt) or read online for free. the documents contain data sets and calculations for facebook usage and online games. Summary measures describing a population, called parameters, are denoted with greek letters. important population parameters are the population mean, variance, and standard deviation. which measure to choose? the mean is generally used, unless extreme values (outliers) exist.

Module 1 Pdf Statistics Level Of Measurement In chapter 2 we discussed how to summarize data using different methods and to display data using graphs. graphs are one important component of statistics; however, it is also important to numerically describe the main characteristics of a data set. In this module, we will focus on the ungrouped data and numerical characteristics of a sample.

To make a dotplot, draw a number line and a for each datum above its value on the line. e.g. there's a dotplot above.

This area of statistics is called “descriptive statistics”. in this module, you will learn how to calculate, and even more importantly how to interpret these measurements and graphs. Ordinal variables frequently are given numerical variable values, but these values are substitutes for a characteristic and are not intrinsically numbers. for example when the variable is severity of cancer, a value of 4 means an individual’s cancer is at an advanced stage and not easily treatable. Note: an important numerical measure of the shape of a distribution is called skewness. case 1 symmetric (skewness = 0); case 2 left skewed (skewness < 0); case 3 right skewness (skewness > 0). If every measure appears the same number of times, then the set of data has no mode. the distribution is unimodal if there’s only one mode, bimodal if two, and trimodal if three.
