## MCQ on Measurement Terminology

##### Que.1 The study of relationship between the input and output, then the input is invariant with respect to time is called as,
1. Static Characteristic of an instrument
2. Dynamic Characteristic of an Instrument
3. Variable Characteristics of an Instrument
4. None of the above

#### Option 1: Static Characteristic of an instrument

##### Que.2 The desirable Static characteristic of a measuring system are
1. Accuracy & Reproducibility
2. Accuracy, Sensitivity & Reproducibility
4. Static Error

#### Option 2: Accuracy, Sensitivity & Reproducibility

##### Que.3 The ability to give same output every time when same input value is applied is known as
1. Stability
2. Accuracy
3. Repeatability
4. Sensitivity

#### Option 3: Repeatability

Explanation:Repeatability (or test–retest reliability) is often used to describe the variation in successive measurements of the same variable taken under the same conditions (e.g., same observer, location, instrument, and procedure) in a short period of time.
##### Que.4 Change in output of device with change in input of sensor is called
1. Threshold
2. Sensitivity
3. repeatability
4. accuracy

#### Option 3: Sensitivity

Explanation:
Sensitivity
It is the ratio of change in output (or response) of the instrument to change in input or measured variable
A higher sensitivity indicates that the system can respond to even the smallest input
1. Resolution
2. Precision
3. Accuracy
4. Scale

1. Accuracy
2. Correction
3. Precision
4. Uncertainty

1. accuracy
2. Sensitivity
3. Stability
4. Linearity

#### Option 3: Stability

##### Que.8 Precision is the _____.
1. Degree of exactness
2. Ability to response
3. Closeness of an agreement
4. True value of measured variable

#### Option 2: Degree of exactness

Explanation:
Precision is the measure of consistency or repeatability of measurements i.e. successive readings in an instrument should not differ.
##### Que.9 Error of measurement is the difference between
1. True value & measured Value
2. Precision & True value
3. Measured Value & Precision
4. None of the above

#### Option 1: True value & measured Valuee
