The type of error that reduces the precision of a measurement system due to factors like noise is called random error. Random errors are unpredictable fluctuations in measurements that can lead to variations in the measured values.
Factors affecting accuracy in measurement include calibration of instruments, human error, and environmental conditions. Factors affecting precision include repeatability of measurements, instrument resolution, and presence of systematic errors. Regular calibration, training of personnel, and controlling environmental conditions can help improve both accuracy and precision in measurements.
The accuracy of a measurement is determined by how close the measured value is to the true value of the quantity being measured. Factors that can affect accuracy include the precision of the measuring instrument, the skill of the person taking the measurement, and any systematic errors or biases in the measurement process.
Precision is important in measurement because it reflects the degree of accuracy and reliability in a measurement process. It helps in minimizing errors and variations in data, providing consistency and repeatability in results. High precision ensures that measurements are closer to the true value, making the data more trustworthy and useful for decision-making.
The accuracy of a measurement is determined by how closely the measured value corresponds to the true value of the quantity being measured. Factors that can affect accuracy include the precision of the measuring tool, human error, calibration of instruments, and systematic errors in the measurement process.
Precision refers to the consistency of measurements, with high precision meaning that repeated measurements yield similar results. Accuracy, on the other hand, refers to how close a measurement is to the true or accepted value. In practical terms, precision pertains to random errors in measurements, while accuracy accounts for systematic errors.

poor precision in scientific measurement may arise?
Systematic errors: These are consistent errors that affect measurements in the same way each time, such as an incorrectly calibrated instrument. Random errors: These errors are unpredictable and can vary in magnitude and direction with each measurement, often caused by factors like human error or external conditions. Instrumental errors: Stemming from limitations in the measuring device, these errors can impact accuracy and precision of measurements.
The precision of the data is limited by the measurement of volume, as small changes or errors in volume measurements can result in significant variations in the calculated values. Additionally, volume measurements may be subject to inaccuracies due to factors such as meniscus error and the calibration of measuring instruments.

A lens with a large radius of curvature allows for a greater region of interference fringes to be observed, making it easier to measure the diameter of the rings accurately. This increases the precision of the experiment and reduces errors in measurement. Additionally, a large radius of curvature reduces the curvature of the lens surfaces, leading to more uniform and symmetrical interference patterns.
The availability of tools can impact the precision of a measurement by influencing the accuracy and sensitivity of the measurements being taken. Having high-quality, calibrated tools can improve precision by reducing errors and providing more precise readings. On the other hand, using low-quality or inadequate tools can introduce errors and reduce the overall precision of the measurement.
Precision in using a thermometer refers to the degree of consistency or reproducibility in temperature measurements. It is important to ensure that the thermometer is accurate and calibrated properly to provide reliable and consistent results. Additionally, following proper measurement techniques and handling procedures can help minimize errors and improve precision in temperature readings.
Significant figures are important in measurement because they indicate the precision of a measurement. They help communicate the reliability and accuracy of the measurement to others. By using the appropriate number of significant figures, we can avoid misinterpretations and errors in calculations.
