Editing Snowball sampling (section)

===Example used in research===
Virtual snowball sampling technique was used in order to find participants for the study of a minority group – Argentinian entrepreneurs living in Spain. About 60 percent of this population has double nationality – both Spanish and Argentinian. Spanish national statistics classifies them as European citizens only and there is no information about the place of birth tied to the profiles of entrepreneurs in Spain either. Therefore, referring to national statistics only, made it impossible to build a [[sample frame]] for this research. The use of virtual networks in this example of hard to reach population, increased the number of participating subjects and as a consequence, improved the representativeness of results of the study.<ref name="Baltar"/>
