3.1.3 Correct rejection / false alarm results
The correct rejection rate and the related measurement of false alarms were measured for each participant considering all casting types, as well as for the 4XX casting type alone. The unpaired Student’s T-Test was used to help determine whether the sample means of the correct rejection rate were significantly different between the groups.
The standard deviations were approximately equal, and the sample means,
standard deviations, and number of participants in each group were known.
The correct rejection rate is directly related to the false alarm rate. The false alarm rate can be calculated by subtracting the correct rejection rate from 1.
