Which part of an investigation is only found in an experimental investigation?

Answer 1

The part of an investigation that is only found in an experimental investigation is the manipulation of an independent variable. In experimental investigations, researchers deliberately change the independent variable to observe the effect on the dependent variable. This manipulation allows for the establishment of cause-and-effect relationships, which is a key component of experimental design. Control over the independent variable is a defining feature of experimental investigations that sets them apart from other types of research designs.

Answer 2

Ah, in an experimental investigation, the part that is unique is the controlled experiment. This is where variables are carefully manipulated and controlled to observe the effects on the outcome. It's like painting a beautiful landscape, where each brushstroke is purposeful and intentional to create a masterpiece.

Answer 3

In an experimental investigation, the researcher conducts experiments and manipulates variables to observe their effects. This process allows for establishing cause-and-effect relationships between variables, which is a unique aspect compared to other types of investigations.
