The error analysis should then mention sources of error that explain why your results and your expectations differ. Sources of error must be specific.

What are sources of error in a lab report?

Common sources of error include instrumental, environmental, procedural, and human. All of these errors can be either random or systematic depending on how they affect the results. Instrumental error happens when the instruments being used are inaccurate, such as a balance that does not work (SF Fig. 1.4).

error. Do not quote human error as a source of experimental error in any lab report! Random errors are unavoidable variations that will either increase or decrease a given measurement.

What could go wrong in a lab?

Those are life’s nine hazards and you should look for them before beginning an experiment. What kinds of emergency situations can you anticipate? Fires, explosions, electrical shocks, bleeding, burns, poisonings, slips and falls, spills, and natural disasters should be considered.

How common are lab errors?

By this definition, failures in laboratory tests certainly qualify. Lab test failures contribute to delayed or wrong diagnoses and unnecessary costs and care. For context, a 2014 study estimated that diagnostic errors happen about 12 million times per year in U.S. outpatients. This represents 1 in 20 adults.

What are some examples of experimental errors?
