6. Precision of an instrument is defined as a. Closeness of output to the true value b. Change in output for every change in input c. Degree of freedom from random errors d. Both (a) and (b) 7. An instrument with high precision implies a. High accuracy b. Low accuracy c. Does not imply anything about measurement accuracy d. None of these 8. Low accuracy measurements from a high precision instrument are normally caused by a. Bias in the measurement b. Human errors c. Instrumental defect d. Low temperature 9. Choose the correct option. 1. Repeatability means the closeness of output readings when the same input is applied repetitively over a short period of time, with the same measurement conditions and same instruments. II. Reproducibility means the closeness of output readings for the same input when there are changes in the method of measurement and conditions of measurement a. Both I and II are correct b. Only I is correct c. Only II is correct d. Both are incorrect
