Question

2. The errors are generated when only
required significant digit are retained in the number
andremaining are discarded
a. Rounding off
b. Truncation error
c. Inherent error
d. Manual error​

Answer 1

Concept:

Error in mathematics is the difference between true and approximate value. In statistics errors is common.

Given:

Four options that depicts different types of errors.

Find:

The errors are generated when only required significant digit are retained in the number andremaining are discarded.

Solution:

According to the problem,

Option $a)$  is correct.

The errors that are generated when only brequired significant digit are retained in the number and remaining are discarded is called Rounding off.

So option $a)$ Rounding off is correct.

The given answer is Truncation error and the actual answer is Rounding off. So, option $b)$ is incorrect option.

The given answer is Inherent error and the actual answer is Rounding off. So, option $c)$ is incorrect option.

The given answer is Manual error and the actual answer is Rounding off. So, option $d)$ is incorrect option.

Hence, option $a)$ Rounding off is correct option.
