Correlational Research Broadens the Scope of Phenomena Beyond Experimental Research

question 112

Multiple Choice

Correlational research broadens the scope of phenomena beyond experimental research because it

• A) allows investigators to do research outside a laboratory setting.
• B) provides a way to investigate variables that cannot be manipulated.
• C) does not require that the variables be causally related to each other.
• D) involves research that does not intrude into the subjects' natural settings.

Identify and describe the components and function of plant vascular systems.

Understand the chemical composition and functional roles of key plant polymers and molecules.

Describe the growth patterns and lifecycle stages of plants.

Define the structural and functional characteristics of plant organs.

Definitions:

SST

A statistical measure in analysis of variance, representing the total variation in a dataset (Sum of Squares Total).

Factorial Research Designs

Experimental designs that allow researchers to examine the effects of two or more independent variables on a dependent variable, as well as the interaction effects between variables.

Interaction Effect

The effect on a dependent variable that arises from the combination of two or more independent variables, rather than from any single variable.

Dependent Variables

Variables in an experiment or study that are expected to change as a result of changes in the independent variable.
