What is the most important part of any scientific exploration?
The hypothesis
What happens when the results of a study fail to support the original hypothesis?

What is a hypothesis?
A tentative statement about the relationship between two or more variables
Study Notes
- A hypothesis is a tentative statement about the relationship between two or more variables.
- A hypothesis is based on research on a topic and can be tested.
- Operational definitions are important for accurately measuring variables in a study.
- A variable is something that can be changed and manipulated and must be defined in a precise way.
- Precise descriptions of variables are important for understanding the results of a study.
- Measuring variables in a study can be difficult, but by defining them operationally, researchers can better understand the results.
- The hypothesis is a critical part of any scientific exploration.
- The hypothesis represents what researchers expect to find in a study or experiment.
- In some cases, the original hypothesis will be supported and the researchers will find evidence supporting their expectations about the nature of the relationship between different variables.
- In other situations, the results of the study might fail to support the original hypothesis.
