Validity
Tries to answer the question “Am I really measuring what I am trying to measure?” Validity refers to the technique and apparatus used for collecting the data. In a valid experiment all variables are kept constant apart from those being investigated. Normally only one variable is investigated at a time. Validity can be improved by reducing any uncertainties (or errors). Validity is not really about
errors caused by human beings when taking readings.
