what are some potential sources of error in your measurement

Solution

The potential sources of errors during measurement are mainly through “recording the results” based on sample size. Selection bias and information can be seen during the measurement, a potential indicatior of error during measurement. Systematic error and random error is mainly due to inappropriate subject characteristics, and incorrect or distortion of results due to misinterpretation of results (confounding bias) during measurement

For example,

The following are the sources of error in blood cell count with haemocytometer:

1). Presence of blood clots in the sample and non-uniform suspensions

2). Errors in dilution pipettes

3). Improper filling of chambers of haemocytometer and uneven spread of the sample

4). Presence of air bubbles due to improper placing of cover slips

5). Failure in adaptation of conventional counting methods like counting cells lying on border -lines
