What is the difference between a hypothesis and a problem? A hypothesis (plural hypotheses) is a precise, testable statement of what the researcher(s) predict will be the outcome of the study. Key difference between the above two forms (research question/problem statement & its related hypothesis): The research question or problem statement is in "open-ended" form, while the hypothesis states a definite outcome or set of outcomes that we might … Definitions of hypothesis and research questions Hypothesis may be defined as a guess or a hunch or an assumption. It identifies the gap between the current (problem) state and desired (goal) state of a process or product.

Having identified a research problem, the researcher should then formulate a research hypothesis, which defines the relationship between one or two variables. So the null hypothesis and alternative hypothesis are as follows, Null Hypothesis: There is no difference in the means between the two countries; Alternative Hypothesis: there is a difference in the means between the two countries; Step 2: This usually involves proposing a possible relationship between two variables: the independent variable (what the researcher changes) and the dependent variable (what the research measures). Problem statement: What would happen if bounce heights of a ball were measured at different temperatures? Lucy B. Trice and Kathaleen C. Bloom. The research problem determines the steps required to conduct the research, and for this reason, a good research problem should be well formulated. A generalized form of the final hypothesis (not the null hypothesis) can be used as a thesis statement. Problem Statement WHAT IS THE PROBLEM? Alternative hypothesis defines what the hypothesis test is determined to accomplish, whereas, a null hypothesis is a theoretical statement that has been presented because of its use as a basis for an argument or because it is believed to be correct but has not been proved.
