Statistical Tests
DataLab offers various statistical tests to be performed. The general procedure for performing any statistical test is as follows: 1) mark the data to be tested. Depending on the test to be performed it may be required to mark two blocks of data 2) select the test to be performed by clicking the corresponding button 3) reply to the questions asked by DataLab (if any) 4) the results are displayed in the protocol window Please note, that the statistical tests as implemented in DataLab are performed on an "as is" basis.
