12C H A P T E R Types of Statistical Tests Statistics is the essence of the scientific method—it is used across all major disciplines. —D. B. Owen and Nancy R. Mann1 All statistical tests are designed to answer the question of whether or not to reject the null hypothesis. The ...

A Pearson’schi-square testis astatistical testfor categorical data. It is used to determine whether your data are significantly different from what you expected. There are two types of Pearson’s chi-square tests: Thechi-square goodness of fit testis used to test whether the frequency distributi...
Statistical tests work by calculating a test statistic –a number that describes how much the relationship between variables in your test differs from the null hypothesis of no relationship.It then calculates a p value (probability value). The p-value estimates how likely it is that you would ...
Mauchly’s test for sphericity can be run in the majority of statistical software, where it tends to be the default test for sphericity. Mauchly’s test is ideal for mid-size samples. It may fail to detect sphericity in small samples and it may over-detect in large samples. If the test...
More than 800 million people suffer from kidney disease, yet the mechanism of kidney dysfunction is poorly understood. In the present study, we define the genetic association with kidney function in 1.5 million individuals and identify 878 (126 new) loci

Microsoft Excel has built-in functions to perform some of the calculations needed for statistical significance tests. To perform a chi-squared test, type =CHISQ.TEST(ActualRange, ExpectedRange), where the arguments are arrays of cells. To measure a p-value, use the function =T.TEST. ...
