Are speci c statements about how variables will relate to one another in a research study (rohall et. al, 2014, 57) Statement seeking to test; trying to con rm or reject. In positivist stream in thought; in quantitative research. Independent (lead to change) and dependant variables (change as a result of the independent variable) *just because have iv and dv, does not mean dependant variable is going to change, sometimes no effect. Refers to a measurable concept (can break down into something more tangible) Uses random selection methods, associated with quantitative methods. Hierarchy - greater chance at being generalizable, less sampling error/bias: non-probability sampling. Does not use random selection methods, associated with qualitative methods. Underpins different types of research designs in social research, both quantitative and qualitative. Results remain the same each time the same measure is used on the same subject; no change to conditions.
