An experiment was conducted to investigate the effects of different types of music on the growth of plants. The four types of mu
sic -- rock, heavy metal, country, and classical -- were played. The growth of bean plants was then measured. In this experiment, the independent variable is
In an experimental study, an independent variable is one that you change or alter to examine its effects. It is named "independent" because it is unaffected by any other study variables.
In order to conduct a valid experiment, you must randomly assign volunteers to different levels of an independent variable.
Dependent variables
A dependent variable is one that is altered as a result of the modification of an independent variable.
The independent variable "depends" on the outcome you're interested in measuring.
After changing the independent variable, you record the dependent variable.
By performing statistical studies, you can utilize this measurement data to determine whether and how much your independent variable affects the dependent variable.
Thus, in the above experiment, the type of music played is the independent variable and the growth of the bean plants is the dependent variable.
Answer: One way the land is shaped by erosion and deposition can be illustrated is through the use of a water source, where the heavy sediments will stay at the bottom of the stream, and the light particles get washed away, leaving a rocky riverbed, rocky.
