Count dates greater than or equal to another date. =COUNTIF(B2:B10,>=6/1/2014) Count the number of cells in the range B2:B10 with a date greater than or equal to 6/1/2014. Count dates greater than or equal to a date in another cell, minus x days. =COUNTIF(B2:B10,>=&B2-7) Count the number of cells in the range B2:B10 with a date greater than or equal to the date in B2 minus 7 days.
A polygraph is a machine, or a test using said machine, which measures the changes in a person's body, such as pulse, breathing rate, and skin temperature.It is used as a lie detection test.It is based on the principle that when lying, one will become nervous and have an increased pulse and need for air. polygraph is a machine, or a test using said machine, which measures the changes in a person's body, such as pulse, breathing rate, and skin temperature.
The instrument typically used to conduct polygraph tests consists of a physiological recorder that assesses three indicators of autonomic arousal: heart rate/blood pressure, respiration, and skin conductivity. Most examiners today use computerized recording systems.ome confusion about polygraph test accuracy arises because they are used for different purposes, and for each context somewhat different theory and research is applicable. Thus, for example, virtually no research assesses the type of test and procedure used to screen individuals for jobs and security clearances.
