Section 11-4 McNemar’s Test for Matched Pairs. Key Concept.

ByNonparametric tests, rank-based tests, chi-square tests. Parametric tests. Parameter: a parameter is a number characterizing an aspect of a population (such as the mean of some variable for the population), or that characterizes a theoretical distribution shape.

ByC ontingency (frequency ) tables. Dependence of two qualitative variables. Examples of problems. Is survival of a person send to choleric area dependent on the fact whether the person have been vaccinated against cholera or not? Is there any connection between hair colour and sex?

ByStatistical Tests to Analyze the Categorical Data. Types of Categorical Data. Types of Analysis for Categorical Data. THE CHI-SQUARE TEST. BACKGROUND AND NEED OF THE TEST Data collected in the field of medicine is often qualitative.

ByContingency Tables. Often we have limited measurement of our data. Contingency Tables are a means of looking at the impact of nominal and ordinal measures on each other. They are called contingency tables because one variables value is contingent upon the other.

BySTT430/530: Nonparametric Statistics. Chapter 7: Basic Tests for Three or More Samples Dr. Cuixian Chen. Ch7 Basic test for three or more samples. Example 7.1. Given k independent samples from normal distributions all with the same (but usually unknown) variance and means μ1, μ2, . . . , μk.

ByCHI-SQUARE( X 2 ) DISTRIBUTION. Chi-Square Test. CHI-SQUARE( X 2 ) DISTRIBUTION. PROPERTIES: 1.It is one of the most widely used distribution in statistical applications 2.This distribution may be derived from normal distribution 3.This distribution assumes values from ( zero to + infinity).

ByFrequency Tables. Statistics 2126. Introduction. Say we have a question like “Where are you from?” or “What is your favourite hockey team?” How would we find out if we have some sort of effect How would the population be distributed? We have to somehow come up with a ‘chance’ distribution.

ByChi Square. Chi Square. z, t and F tests are parametric (assume a normal distribution) Chi square is non-parametric (distribution free) A test of significance when data are expressed in frequencies or are expressed in percentages or proportions that can be reduced to frequencies. Three uses:
