Compare and contrast random errors and systematic errors
Random errors and Systematic errors both cause harm to the experiment results, but Random errors are caused by random occurrences, and systematic errors are caused by issues in measuring instruments.

Introduced when the researcher fails to take into account the inherent biases liable in most types of experiments
Selection bias
occurs when the process of sampling actually introduces an inherent bias into the study
Procedural bias
an unfair amount of pressure is applied to the subjects being studied
Reporting bias
