Chapter 11: Chi-Square and ANOVA Tests

Chapter 11: Chi-Square Tests and ANOVA 393 Chapter 11: Chi-Square and ANOVA Tests This Chapter presents material on three more hypothesis Tests . One is used to determine significant relationship between two qualitative variables, the second is used to determine if the sample data has a particular distribution, and the last is used to determine significant relationships between means of 3 or more samples. Section : Chi-Square Test for Independence Remember, qualitative data is where you collect data on individuals that are categories or names. Then you would count how many of the individuals had particular qualities. An example is that there is a theory that there is a relationship between breastfeeding and autism.

the Chi-Square Test for Dependence, but for historical reasons it is known as the test for independence. Just as with previous hypothesis tests, all the steps are the same except for the assumptions and the test statistic. Hypothesis Test for Chi-Square Test 1. State the null and alternative hypotheses and the level of significance

Chapter 5: Discrete Probability Distributions

coconino.edu

Chapter 5: Discrete Probability Distributions 158 This is a probability distribution since you have the x value and the probabilities that go with it, all of the probabilities are between zero and one, and the sum of all of the probabilities is one. You can give a probability distribution in table form (as in table #5.1.1) or as a graph.

Chapter 6: Continuous Probability Distributions

Chapter 6: Continuous Probability Distributions 193 Section 6.3: Finding Probabilities for the Normal Distribution The Empirical Rule is just an approximation and only works for certain values. What if you want to find the probability for x values that are not integer multiples of the standard deviation? The probability is the area under the curve.

Chapter 6: Graph Theory

Leonhard Euler first discussed and used Euler paths and circuits in 1736. Rather than finding a minimum spanning tree that visits every vertex of a graph, an Euler path or circuit can be used to find a way to visit every edge of a graph once and only once. This would be useful for checking parking meters along the streets of a city, patrolling the

Chapter 10: Regression and Correlation

coconino.edu

Chapter 10: Regression and Correlation 346 The independent variable, also called the explanatory variable or predictor variable, is the x-value in the equation.The independent variable is the one that you use to predict what the other variable is. The dependent variable depends on what independent value you pick.

Chi Square: Allows you to test whether there is a relationship between two variables. BUT, it does not tell you the direction or the size of the relationship. Null Hypothesis: There is no relationship between the two variables. When you reject the null hypothesis with a Chi-Square, you are saying that there is a relationship between the two ...
