3. Collecting/gathering data

"Statistical designs for producing trustworthy data are perhaps the single most influential contribution of statistics to the advance of knowledge. In this century [the 20th], random sampling and randomized comparative experiments have revolutionized the practice of many fields of applied science." --Moore & McCabe, IPS 2/e, p. 221
