Why is it important to analyze an experiment for experimental variables?

An experiment is typically carried out by manipulating a variable, called the independent variable, affecting the experimental group. Researchers only want to measure the effect of the independent variable(s) when conducting an experiment, allowing them to conclude that this was the reason for the effect.

Why is experimental method important?

How exactly do researchers investigate the human mind and behavior? While there are a number of different research techniques, the experimental method allows researchers to look at cause-and-effect relationships.

What should one consider when analyzing the results of an experiment?

Explanation: Empirical evidence are the observations and data values collected during the experiment by using the senses. Like if your are experimenting involving a chemical reaction, the temperate or color changes during the reaction should be counted in the interpretation of the results.
