Interpret statistical significance for results from commonly used statistical tests. 10.Describe the similarities and differences between statistical tests; state how to apply them appropriately. 11. WebThe basic idea behind the test is to compare the observed values in your data to the expected values that you would see if the null hypothesis is true. There are two commonly used Chi-square tests: the Chi-square goodness of fit test and the Chi-square test of independence. Both tests involve variables that divide your data into categories.
Webof the sample mean as our test statistic. We know that if a random variable is normally distributed (as it is the case for X ), subtracting the mean and dividing by standard deviation creates a new random variable with standard normal distribution, Z ˘N(0;1): We refer to the standardized value of the observed test statistic as the z-score, z ...
