Q. |
What is the relation between variation due to observation, manufacturing process and measuring process of a product? |
A. | σobservation = σprocess + σmeasurement |
B. | σobservation = σprocess – σmeasurement |
C. | σobservation = σprocess * σmeasurement |
D. | σobservation = σprocess / σmeasurement |
Answer» A. σobservation = σprocess + σmeasurement | |
Explanation: the variation in the observation depends upon the variation in the product due to manufacturing process and variation due to measuring process. in order to keep σobservation minimum measurement should be kept minimum so that product as a whole is reliable. |
