Students should recognize the research situations in which a chi-square test is appropriate. Chi-square tests are intended for research questions concerning the proportion of the population in different categories. For a chi-square test, there is not a numerical score for each individual and you do not compute a sample mean or a sample variance. Instead, each individual is simply classified into a category and you count the number of individuals in each category. The resulting data are called observed frequencies.

It is similar to a single-sample t test because it uses one sample to test a hypothesis about one population.b. It is similar to a correlation because it uses one sample to evaluate the relationship between two variables.c. It is similar to an independent-measures t test because it uses separate samples to evaluate the difference between separate populations.d. It is similar to both a correlation and an independent-measures t test because it can be used to evaluate a relationship between variables or a difference between populations.Explanationitur laoreet.

Lorem ipsum dolor s Related ExercisesWhat accurately describes the chiThe Chi-square test of independence checks whether two variables are likely to be related or not. We have counts for two categorical or nominal variables. We also have an idea that the two variables are not related. The test gives us a way to decide if our idea is plausible or not.
What does the chiUse the chi-square test for independence to determine whether there is a significant relationship between two categorical variables. Using sample data, find the degrees of freedom, expected frequencies, test statistic, and the P-value associated with the test statistic.
Which of the following accurately describes the chiWhich of the following accurately describes the chi-square distribution? Positively skewed with all values greater than or equal to zero.
Which of the following accurately describes the chiWhich of the following accurately describes the chi-square test for goodness of fit? It is similar to a single-sample t test because it uses one sample to test a hypothesis about one population.
