Experiments do test a hypothesis, i.e. an anticipated relationship between the variables. In this type of research, a researcher compares an experimental group to a control group. An experimental unit is that which receives a treatment while controls are not subject to any treatment. Random assignment of people who will carry out the research on the experimental group is done by the researcher before the research begins (Brent & Lewis, 2014).
Data received from social surveys are considered very valid and reliable especially when questionnaires are used to conduct the study. This is because proper sampling procedures are employed when studying the particular population. Furthermore, social surveys give room for the respondents to remain anonymous especially when the topics being studied are considered delicate. Anotherstrength of this technique is that conducting interviews can lead to a very representative sample of the population because the researchers can as well reach the respondents who cannot read and write (Covington, 2008).
This method of research involves learning about a particular group’s way of life and beliefs through interacting with the group over a given period. The researcher encounters the group and can as well conduct interviews and discussions with the individual members of the group over the period of their interaction (Nanda & Warms, 2013).
