I will add a twist. Whether exploratory or confirmatory, there are always research question(s) and a hypothesis/hypotheses. Our interest and expectations drive all research--even qualitative. We are not blank slates. Now, questions can be broad, such as "is there a relationship," to narrow, deterministic, such as"x caused y." We do our readers a disservice when we hide our agenda and preconceptions.
The research process starts with a literature review to find the research gap. Thereafter, research objectives and supporting hypotheses are developed. To beautify quantitative research, research questions should be designed.
I don't think that purely descriptive or exploratory research goals have meaningful questions beyond, "What would I find if..." For a research question to be meaningful, it has to have some substantive content.
The research hypotheses are creating the conceptual framework based on the literature review. It is needed to answer the research questions regarding the new findings of research objectives. Accepted or rejected the research hypotheses are also new, and to answer this question, the researchers should add research hypotheses for the statistics, such as Chi-square, t-test, ANOVA, Pearson Correlation, Multiple Regression Analysis, and SEM.
