Explain why there are sources of error in collecting and analyzing data. what can scientists do to limit the amount of errors?

Errors often occurs during the phase of the data collection and processing stages. To decrease the number of errors it is important for scientist to do the measurements right. The most common are random errors (by unknwn changes) in measurement instrument use and calibration or faulty measurement equipment. You can reduce the random errors by taking multiple measurements and increasing sample sizes.
