Question

What is mean by systematic errors? Give the techniques to reduce systematic errors.

Answer 1

Systematic errors are the type of errors in which there is a manfucaturing error of the physical measuring instrument that we use for experiment, This occurs for example, if the thermometer isn't callibrated correctky and thus suppose your thermometer shows a rise out just 0.99° C for actual rise of 1° C in temperature.
Thus, systematic errors can be reduced by using more and more different accurately callibrated devices for the measurements in the same experiment and take a number of different readings using those different measuring devices.

Answer 2

Hi mate , here is your answer

Systematic errors are the errors that effect the whole comprising group in a similar manner or way and occurs in the same direction .The techniques to reduced systematic errors are :

           1) Instrument must be design carefully .

           2) By introducing an equal and opposite environmental input for compensating the event of environmental input in a measurement system                                        

           3) By adding high gain feedback to measurement system .

I hope you are satisfied with my answer........!
