10 Questions
What is the purpose of conducting experiments in scientific research?
To support or reject hypotheses rather than proving or disproving them.
What happens to a hypothesis once it has been supported by a significant amount of peer reviewed experiments?
It can be promoted to become a theory.
What is peer review in scientific research?
When scientists in the same field evaluate the work and determine its credibility.
Define scientific theory.
An explanation for the natural world that brings together facts and hypotheses and is strongly supported by empirical research.
How is a scientific theory different from a theory in colloquial usage?
A scientific theory is strongly supported and widely believed to be true, while a colloquial theory may describe any kind of idea without strong evidence.
What is bias and how does it impact scientific research?
Bias is a prejudice towards a particular outcome that can impact the interpretation of data and conclusions.
What is the purpose of the scientific method?
To try to avoid bias and ensure the validity of experiments and conclusions.
How can bias in data collection and conclusion formation affect the credibility of an experiment's results?
It can lead to serious problems in the accuracy and trustworthiness of the claims.
What is the role of peer review and repeat testing in scientific research?
To flag errors and biases and correct them before the data is published or accepted as valid.
What can cause a scientific theory to be rejected?
Large discoveries and new technologies that contradict the theory's explanations and evidence.
Quiz: Understanding Experimental Design in Health Research Test your knowledge on experimental design in health research with this quiz. Learn about the key elements of an experiment and their application in studying the impacts of exercise on diabetes. Explore how variables such as the independent variable (IV) - in this case, daily walking - and the dependent variable (DV) - resting blood sugar levels - are utilized to draw meaningful conclusions. Challenge yourself and enhance your understanding of experimental design in health research.
