The main difference between study and experiment is that a study is an investigation or analysis of a particular subject or phenomenon, often involving observation and data collection, while an experiment is a controlled test or investigation designed to discover or demonstrate a specific scientific principle or hypothesis.

In a study, researchers typically gather existing data or collect new data through surveys, interviews, or observations to analyze and draw conclusions about a specific topic. Studies can be used to explore various aspects of a subject, such as its prevalence, trends, or impact, and may involve statistical analysis or qualitative interpretation.

On the other hand, an experiment involves deliberately manipulating variables in a controlled setting to test a hypothesis or cause-and-effect relationship. Experiments are designed to answer specific research questions and often involve the use of a control group, independent and dependent variables, and careful measurement and observation to draw conclusions.

In summary, while a study focuses on observing and analyzing data to understand a specific topic, an experiment involves conducting controlled tests to establish a cause-and-effect relationship or to demonstrate a scientific principle.
