Peer review involves having other experts in the field evaluate the research for accuracy, validity, and significance before publication.
The independent variable is the factor that the researcher alters to observe its effects on the dependent variable.
Quantitative data involves numerical measurements and statistical analysis to provide objective results in scientific research.
The control group serves as a baseline and is not exposed to the experimental treatment, allowing researchers to compare its effects with those on the experimental group.
A hypothesis is a testable prediction or proposed explanation for an observed phenomenon, which can be investigated through scientific research.
