Question

What are errors? what are the types of errors?​

Answer 1

Answer:

here's the answer please mark as the brainliest

Explanation:

An error is something you have done which is considered to be incorrect or wrong, or which should not have been done. There are three types of error: syntax errors, logical errors and run-time errors. (Logical errors are also called semantic errors). We discussed syntax errors in our note on data type errors.

Answer 2

Explanation:

An error may be defined as the difference between the measured value and the actual value. For example, if the two operators use the same device or instrument for a measurement, it is not necessary that they may get similar results. The difference that occurs between both the measurements is referred to as an ERROR.

Systematic Errors: Systematic errors can be better understood if we divide it into subgroups;

Instrumental Errors: These errors arise due to faulty construction and calibration of the measuring instruments. Such errors arise due to the hysteresis of the equipment or due to friction. Lots of the time, the equipment being used is faulty due to misuse or neglect which changes the reading of the equipment. The zero error is a very common type of error. This error is common in devices like vernier calipers and screw gauge. The zero error can be either positive or negative. Sometimes the readings of the scale are worn off and this can also lead to a bad reading.

Random Error: The random errors are those errors, which occur irregularly and hence are random. These can arise due to random and unpredictable fluctuations in experimental conditions (e.g. unpredictable fluctuations in temperature, voltage supply, mechanical vibrations of experimental set-ups, etc, errors by the observer taking readings, etc. For example, when the same person repeats the same observation, it is very likely that he may get different readings every time.
