Final answer:
The scientific method is a method of research with defined steps that include experiments and careful observation. Empirical evidence refers to evidence obtained through observation. A hypothesis is a proposed explanation while a theory is a thoroughly tested and confirmed explanation.
Step-by-step explanation:
The scientific method is a method of research with defined steps that include experiments and careful observation.
The steps of the scientific method are as follows:
- Make observations
- Identify a question based on the observation
- Research what is already known about the observation
- Form a hypothesis
- Test the hypothesis
Empirical evidence refers to evidence that is obtained through observation and measurement in the physical world.
A hypothesis is a proposed explanation for a natural phenomenon, while a theory is a thoroughly tested and confirmed explanation for a set of observations.
Operational definitions are important in scientific research as they define concepts in a way that allows them to be measured objectively.
Replication is crucial in science as it involves repeating a study to determine if the same results can be obtained.
Statistics are used to analyze data and draw conclusions from it.
Meta-analysis is a statistical method used to combine the results of multiple studies, increasing the sample size and statistical power.
A statistically significant finding is one that indicates the results are unlikely to be due to chance alone.
