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.
The null hypothesis. All statistical tests involve testing a null hypothesis against an alternative hypothesis. These two terms have specialised meanings, and are not the same as your research question or hypothesis. The null hypothesis and alternative hypothesis can be constructed from the research hypothesis.his section summarises the ways in which the different statistcial tests can be used in Geography. For more information on the different statistical tests, see The Seashore. For more information an excellent source developed in FSC Field Centres is Statistics for Geographers.
