1) A digital thermometer gives readings of 37.12°C, 37.13°C, and 37.12°C when measuring the same sample. What does this demonstrate? a) Calibration b) Precision c) Tolerance d) Accuracy 2) An engineer notes the diameter and depth of a drilled hole on a part drawing. What type of measurement data is this? a) Standard b) Dimensions c) Variation d) Repeatability 3) A technician adjusts a micrometer after comparing it to a certified block. What is this process? a) Repeatability b) Calibration c) Variation d) Precision 4) A machinist uses a reference gauge to verify tool alignment before use. What is this gauge an example of? a) Dimension b) Error of measurement c) Technical drawing d) Standard 5) Multiple samples from the same production batch have slightly different lengths. What is this an example of? a) Accuracy b) Precision c) Variation d) Calibration 6) A technician builds a machine part by following a detailed diagram that includes multiple views and measurements. What tool is being used? a) Tolerance b) Dimensions c) Technical drawing d) Calibration 7) A laser measurement device gives the same reading five times in a row for the same object. What quality does this show? a) Repeatability b) Variation c) Accuracy d) Standard 8) A bolt must be between 15.00 mm and 15.05 mm to pass inspection. This allowable range is known as: a) Calibration b) Accuracy c) Dimensions d) Tolerance 9) Which measurement shows the least precision? a) 5.678 cm b) 5.6 cm c) 5.67 cm d) 5.68 cm 10) An inspector reads 19.8 mm for a shaft that should be 20 mm. What does the 0.2 mm difference represent? a) Error of measurement b) Standard c) Tolerance d) Repeatability 11) A measuring tape shows exactly 100 cm when placed against a known 1-meter standard. What does this indicate? a) Precision b) Accuracy c) Error of measurement d) Variation 12) Why is calibration and using standards critical in engineering measurements? a) To make the tools heavier and more durable b) To reduce the amount of training needed for new employees c) To ensure measurements are consistent and trusted across tools and teams d) To make drawings look more professional
