Question

according to the stream table experiment, which statement correctly identifies the test variable (independent variable) and the outcome variable (dependent variable) of the investigation? the angle of the stream table is the test variable (independent variable) and the type of material is the outcome variable (dependent variable). the distance materials traveled is the test variable (independent variable) and the type of material is the outcome variable (dependent variable). the type of material is the test variable (independent variable) and the distance materials traveled is the outcome variable (dependent variable). the rate of water flow is the test variable (independent variable) and the distance materials traveled is the outcome variable (dependent variable).

Explanation:

The independent variable is manipulated, and the dependent variable is measured. In a stream - table experiment, the type of material can be set (independent), and the distance it travels is measured (dependent).

Answer:

The type of material is the test variable (independent variable) and the distance materials traveled is the outcome variable (dependent variable).
