uncertain
Measurements are off because the tool used isn't precise. Temperature and humidity may affect the results.
Even with no mistakes in a carefully conducted experiment, error is expected. That word error does not mean a mistake, it means that measurements can never find exactly the quantity being measured.Suppose you measure the length of a table top, you might find it's 48.8 inches. Does that mean 48.800000 inches? no it does not, because you can't measure to an accuracy of one millionth of an inch without special equipment. Your experimental error is the difference between your measurement and the exact length of the table.
Calibration error and measurement error. Also, if the measurements are of different objects there may be random error.
the equipment error is the percentage of uncertainty on the equipment, so for example, a measuring cylinder has the percentage error of around 0.5cm3. The only way I know off to reduce error percentage is to well increase sample size/ volume A etc. as the calculation is something like (equipment error / quantity measured x 100) this would mean that having a higher quantity to measure will therefore decrease percentage error. hope it helps.
uncertain
Unsystematic error, also known as random error, refers to chance variations in measurement that are unpredictable and uncontrollable. This type of error often results from factors such as human error, equipment limitations, or environmental conditions, leading to inconsistencies in data measurements. To minimize unsystematic error in observation assessments, it is important to standardize procedures, use quality equipment, and take multiple measurements to account for variability.
Some problems with measuring include inaccuracies due to human error, inconsistent measurement techniques, equipment calibration issues, and environmental factors that can affect measurements.
You can pay off the judgment , prove with a letter or some valid evidence that the judgment was made in error..
To ensure accuracy in measurements, use calibrated instruments, follow proper measurement techniques, double-check measurements when possible, and eliminate sources of error such as parallax or environmental factors. Regularly calibrate equipment and follow standardized procedures to maintain accuracy over time.

Compound error refers to the accumulation of errors in a system or process over time. It occurs when small errors in individual components or stages of a process combine to produce a larger overall error. Sources of compound error can include inaccuracies in measurements, rounding errors, human error, and limitations in equipment or technology.

Sources of error in a chemistry lab include human error (such as inaccurate measurements or improper technique), instrumental errors (like calibration issues or equipment malfunctions), environmental factors (such as temperature or humidity fluctuations), and systematic errors from limitations in the experimental design or methodology.
Some sources of error in respiration measurements include incorrect placement of sensors, movement by the individual during measurement, inaccurate calibration of equipment, and variability in breathing patterns. These errors can lead to inaccurate readings and affect the reliability of respiratory data.

Quantitative error analysis is the process of quantifying uncertainties in measurement data to determine the reliability and precision of the measurements. It involves identifying sources of error, calculating error propagation through calculations, and estimating the overall uncertainty in the final result. This helps in understanding and improving the accuracy of experimental measurements.
