To make gyros, pieces of meat (usually pork) are placed on a tall vertical rotisserie, in the shape of an inverted cone, which turns slowly in front of a source of heat, usually an electric broiler. If the meat is not fatty enough, strips of fat are added so that the roasting meat always remains moist and crisp.
A statistician is someone who works with theoretical or applied statistics. The profession exists in both the private and public sectors. It is common to combine statistical knowledge with expertise in other subjects, and statisticians may work as employees or as statistical consultants.[1][2]
A test statistic is a standardized value that is calculated from sample data during a hypothesis test. You can use test statistics to determine whether to reject the null hypothesis. The test statistic compares your data with what is expected under the null hypothesis. The test statistic is used to calculate the p-value. A test statistic measures the degree of agreement between a sample of data and the null hypothesis. Its observed value changes randomly from one random sample to a different sample.
