Which part of an investigation is only found in an experimental investigation?
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.
When an engineer is making a mixture of metals to make steel for the frame of a building what two properties should the steel have?

What type of structure are ice skates ( soild structure frame structure or shell structure.)?

What are the advantages and disadvantages of ex post facto research?
advantages:its ideal for testing demographic variables which cannot be manipulated. like a non-experimental design it doesn't require much to collect data, but just merely shows effects of a presence or absence of an Independent variable on a Dependent variable.disadvantages:it cannot acquire as much data as an experimental design, the levels of the "IV" are already established. If anything it tries to be an experimental design but it cannot.
