Q5. What is use of timers in JMeter?
Ans. 
Timers in JMeter are used to simulate real user behavior by adding delays between requests.
• Timers help in controlling the load on the server by adding delays between requests.

• They can be used to simulate realistic user behavior by adding random or constant delays.

• Examples of timers in JMeter include Constant Timer, Gaussian Random Timer, and Uniform Random Timer.

Q2. What is the correlation
Ans. 
Correlation is a statistical measure that describes the strength and direction of a relationship between two variables.
• Correlation values range from -1 to 1, with 0 indicating no correlation, 1 indicating a perfect positive correlation, and -1 indicating a perfect negative correlation.

• Positive correlation means that as one variable increases, the other variable also increases. Negative correlation means that as one var...read more
