when should a hypothesis be developed by the researcher during the research process
Empirical research In some fields, quantitative research may begin with a research question (e.g., "Does listening to vocal music during the learning of a word list have an effect on later memory for these words?") which is tested through experimentation. Usually, a researcher has a certain theory regarding the topic under investigation. Based on this theory, statements or hypotheses will be proposed (e.g., "Listening to vocal voice has a negative effect on learning a word list."). From these hypotheses, predictions about specific events are derived (e.g., "People who study a word list while listening to vocal music will remember fewer words on a later memory test than people who study a word list in silence."). These predictions can then be tested with a suitable experiment. Depending on the outcomes of the experiment, the theory on which the hypotheses and predictions were based will be supported or not,[1] or may need to be modified and then subjected to further testing.

Cwm Rhondda Arglwydd, arwain trwy'r anialwch, Fi, bererin gwael ei wedd, Nad oes ynof nerth na bywyd Fel yn gorwedd yn y bedd: Hollalluog, Hollalluog, Ydyw'r Un a'm cwyd i'r lan. Ydyw'r Un a'm cwyd i'r lan Agor y ffynhonnau melus 'N tarddu i maes o'r Graig y sydd; Colofn dân rho'r nos i'm harwain, A rho golofn niwl y dydd; Rho i mi fanna, Rho i mi fanna, Fel na bwyf yn llwfwrhau. Fel na bwyf yn llwfwrhau. Pan yn troedio glan Iorddonen, Par i'm hofnau suddo i gyd; Dwg fi drwy y tonnau geirwon Draw i Ganaan – gartref clyd: Mawl diderfyn. Mawl diderfyn Fydd i'th enw byth am hyn. Fydd i'th enw byth am hyn.
1 + 2 + 3 + 4 + ⋯ which increases without bound as n goes to infinity. Because the sequence of partial sums fails to converge to a finite limit, the series does not have a sum.
