Question

What are errors? Differentiate between systematic and random errors?
​

Answer 1

Answer:

Errors can be divided into two primary kinds, systematic and random errors. Systematic error, as the name implies, is a consistent, repeatable error that deviates from the true value of measurement by a fixed amount. Systematic error is the one that occurs in the same direction each time due to the fault of the measuring device. On the contrary, any type of error that is inconsistent and does not repeat in the same magnitude or direction except by chance is considered to be a random error. Random errors are sometimes called statistical errors

Answer 2

${\huge{\boxed{\tt{\color {indigo}{Answer:}}}}}$

Error is a difference between measured value and the true value of a physical quantity. It gives the uncertainty in the measurement.

☘Systematic Errors:

These are the errors which tend to be in one direction, either positive or negative.

☘Random Errors:

These errors occur irregularly and are random witg respect to size and sign.

They arise due to random and unpredictable fluctuations in experimental conditions. To minimize these errors we repeat the measurement many times and take the average of all measurements as the correct value of measured value.
