A large value for the chi-square statistic indicates the sample data (observed values) do not match the null hypothesis. there is a good fit between the sample data (observed values) and the null hypothesis.     the observed values from the sample data are consistently larger than the expected values. the observed values from the sample data are consistently smaller than the expected values.

You are given a chi square to fill out with 4 different observed values: 0, 54, 36, and 18. These numbers represent the 4 different phenotypes of offspring. If you have an observed value of 0 for one of these variables, can it even be included as a probability? Would that row just be disregarded from the data, and as a result you would have to adjust the degrees of freedom? (From 4 categories to 3, then - 1) Had...

The P-value for a chi-square test is always one-tailed. This is true because of all of the following reasons, EXCEPT: Group of answer choices Observed data that is either higher or lower than the null hypothesis predicts will result in a positive chi-square value. Only a large positive value of chi-square provides stronger evidence to conclude HA. A chi-square distribution is skewed. The chi-square statistic is always positive, unlike a z or t statistic which can be ether positive or...

One of the requirements of a chi-square test is independence - subjects cannot fit in more than one category. This is because of the way the chi-square analysis is set up, as you are looking at predicted and expected ratios. There's another requirement in that categories must be exhaustive - everyone must fit into one of the categories. This is done for the same reason. Do you feel that this is a weakness of chi-square analyses? It's often argued that...
