A hypothesis is what an investigator uses to:
duplicate research findings of other scientists.
frame his/her research question.
explain why he/she obtained a certain result from an experiment.
define the parameters of a research study.
determine what kind of research design to use.
frame his/her research question.
I am pretty sure that it is not duplicate and it is not explain.
The success or failure of attempted persuasion can usually be understood by considering the characteristics of the
A hypothesis is a statement that an investigator forms based on their observations or previous knowledge. It is used to frame their research question and guide their investigation. A hypothesis is essentially a prediction or explanation of a phenomenon that the investigator wants to study.
To determine the answer to this question, we need to understand the purpose and role of a hypothesis in the scientific research process. Let's break down each of the given options to examine their relationship to a hypothesis:
1. Duplicate research findings of other scientists: While the aim of scientific research is to reproduce or replicate previous findings, this is not a direct role of a hypothesis. Rather, a hypothesis guides the investigator's own research question and is based on their own observations or knowledge.
2. Frame his/her research question: This statement accurately describes the role of a hypothesis. A hypothesis helps investigators formulate their research question by suggesting a potential explanation or prediction for the phenomenon they want to study.
3. Explain why he/she obtained a certain result from an experiment: While a hypothesis can provide insights and possible explanations for the results obtained from an experiment, its original purpose is to guide the research question and not solely to explain the obtained results.
4. Define the parameters of a research study: Defining the parameters of a research study, such as the population, variables, and methods, is typically done during the research design phase. While a hypothesis may influence some aspects of the research design, it does not directly define all parameters.
5. Determine what kind of research design to use: The choice of research design is influenced by various factors, including the research question and the available resources. While a hypothesis may guide the design by suggesting which variables to measure or manipulate, it is not the only factor that determines the choice of research design.
Therefore, the correct answer is: frame his/her research question. A hypothesis is used to propose a potential explanation or prediction and helps investigators shape their research question.
