Summary
TLDRIn this informative video, Jessica from Scribbr explores the concept of a hypothesis, using the proverb "an apple a day keeps the doctor away" as a case study. She outlines six essential steps to formulate a strong hypothesis, starting with asking a focused research question and conducting preliminary research. Jessica emphasizes refining the hypothesis to make it specific and testable, and provides examples of phrasing it in various formats. Additionally, she discusses the importance of a null hypothesis in statistical testing. The video is a valuable resource for anyone looking to strengthen their research skills.
Takeaways
- π A hypothesis is a tentative statement predicting what you expect to find in your research.
- π The first step in formulating a hypothesis is to ask a focused, specific, and researchable question.
- π Conduct preliminary research to gather existing knowledge and theories related to your question.
- βοΈ Write your initial answer to the research question in a clear and concise hypothesis statement.
- π Ensure your hypothesis is specific and testable, including relevant variables and the target group.
- π Phrase your hypothesis in three ways: If-Then, correlation, and group comparison.
- β The If-Then form highlights the independent and dependent variables of the hypothesis.
- π A correlation statement describes the expected relationship between variables.
- π₯ The group comparison method contrasts two groups regarding the variable being studied.
- π« Formulate a null hypothesis, which assumes no effect between the variables being studied.
