This solution reviews some of the common types of bias and threats to validity in quantitative research such as history, maturation, regression, selection, mortality, diffusion of treatment, testing, and instrumentation. The tests and measures used to establish the validity and reliability of quantitative research cannot be applied to qualitative research. If more than one person is involved in collecting and analysing the research data, then the chances of personal views influencing the findings will be minimised. Assign patients to study cohorts using rigorous criteria. To remain open minded, alert to foreclosure and to sources of error needs some measure of detachment.
