Which statement is true about population in a quantitative research question? Select all that apply. One, some, or all responses may be correct. In experimental research, the population is divided into two groups, where one group receives the intervention and the other group does not. In comparative research, two groups are derived from two populations. In correlational research, the researcher attempts to derive a connection between X and Y in the specified population. The population is chosen according to the type of research question. In comparative research, it is important for the chosen populations to have all characteristics, except for X to be controlled for, so that there is increased validity in the research results
