Jacksonian seizure: A form of epilepsy involving brief alteration in movement, sensation or nerve function caused by abnormal electrical activity in a localized area of the brain. Jacksonian seizures is a form of simple complex seizures in which the abnormal electrical activity is localized to one region in the brain. Seizures of this type typically cause no change in awareness or alertness. They are transient, fleeting, and ephemeral.
The hypothesis test for this type of data is called a ât-Testâ. A t-Test is commonly used to determine if two different data sets have a different average. In our example, we would like to know if the average ERA is different before and after the alleged drug use.
Making Sense of the Two-Sample T-Test. The two-sample t-test is one of the most commonly used hypothesis tests in Six Sigma work. It is applied to compare whether the average difference between two groups is really significant or if it is due instead to random chance.
