Key Concepts

Experiment

An experiment is a systematic procedure used to investigate a hypothesis or a research question by manipulating one or more independent variables and measuring the effect on dependent variables in controlled conditions. This method allows for the observation of cause-and-effect relationships in a reproducible manner.

Experimental Design

Experimental design refers to the overall strategy used to integrate the different components of the study in a coherent and logical way, ensuring that the experiment effectively tests the hypothesis. It involves planning the manipulation of variables, the establishment of control conditions, and strategies for data collection to ensure reliable and unbiased results.

Variables and Controls

In experiments, variables are elements that can change or be changed. Independent variables are manipulated to observe their effects, while dependent variables are the outcomes measured. Control involves keeping other potential influencing factors constant so that the influence of the independent variables can be isolated and accurately assessed.
