Answer 1

Gross Errors: This category basically takes into account human oversight and other mistakes while reading, recording and the readings.

The most common of errors, the human error in the measurement fall under this category of errors in measurement. For example the person taking the reading from the meter of the instrument he may read 23 as 28. Gross errors can be avoided by using two suitable measures and they are written below:

• A proper care should be taken in reading, recording the data. Also, calculation of error should be done accurately.
• By increasing the number of experimenters we can reduce the gross errors. If each experimenter takes different reading at different points, then by taking average of more readings we can reduce the gross errors
