What about whether a coffee machine was dispensing approximately the same amount of coffee each time? these situations involve testing how well an observed distribution of data fits the expected distribution. these types of scenarios require a hypothesis test using the χ 2 distribution. The chi square goodness of fit test extends inference on proportions to more than two proportions by enabling us to determine if a particular population distribution has changed from a specified form. hypotheses: h0: the proportions are the same as what is claimed. How do we tackle the inference problems arising out of categorical data? in this unit we shall discuss the use of one of the most widely used tests, the chi square test, in this context. to start with, in sec.7.2, we shall consider the use of the chi square test in "goodness of fit" problems.

The distribution of the chi square statistic is called the chi square distribution. in this lesson, we learn to compute the chi square statistic and find the probability associated with the statistic. and we'll work through some chi square examples to illustrate key points. This chapter changes the approach to inferential statistics somewhat by examining whole distributions, and the relationship between two distributions. in doing this, the data is not summarized into a single measure such as the mean, standard deviation or proportion. The chi square test that is conducted on the sample of a smaller size results in the drawing of an inaccurate inference about the data. if the researcher conducts the chi square test on a small sample size, then it may happen that the researcher might end up committing a type ii error. For students preparing for the collegeboard ap statistics exam, a comprehensive understanding of the chi square distribution is essential for tackling problems related to the inference unit effectively.
