In this type of data, Y is called the response variable and X is called the explanatory variable (or sometimes the stimulus), and the relationship is called a .

Because science was still a long way from being able to give a comprehensive account of .
It can cause an obvious change in the internal or external physical condition of an organism.
Difference Between Stimulus and Response | Difference Between | Stimulus vs Response
A stimulus appears as an energy pattern which can affect the behavior of an organism, particularly of man. It is experienced by man through his senses of vision, hearing, touch, taste, and smell.
There are four aspects of a stimulus, namely: A response is the behavior that is manifested by a living organism which is the result of an external or internal stimulus.
It is the activity of the organism or of his body parts as a reaction to the stimulation of his senses.
The detection and receipt of the stimulus by an organism and its conversion into a signal is the response of the organism to the stimulus. The response may be cellular or physical, or it can be behavioral. An example of a cellular response is when a person exhibits allergic reactions to certain substances that he ingests.
Difference Between Stimulus and Response
An example is the feeling of sadness and loneliness when a loved one dies. A stimulus is any agent, condition, action, or activity which arouses a positive or negative reaction while a response is the resulting reaction towards the stimulus.
If the experiment is designed properly see the later sections on experimental designthe explanatory variable cannot be affected by the response, so the relationship is a stimulus-response one.

Soy bean experiment In an experiment, soybean plants were exposed to four different chronic levels of ozone. At each ozone level, soybean yield was measured from five different experimental units soy bean plants. The resulting data are displayed below.
This is experimental data since the agricultural researcher can control the ozone exposure of the different plants the explanatory variable.Understanding Stimulus and Response Connection(Hindi)
Click Take Sample a few times to repeat the experiment and observe that the distribution of ozone concentrations remains the same -- only the response soy bean yield changes in the repetitions of the experiment. If the explanatory variable is not controlled The variables can also be classified into an explanatory variable and response in situations where the values of the explanatory variable are not pre-determined.
If it can be argued that variable X may have an influence on Y, but that Y cannot affect X, then we can again call X the explanatory variable. This type of relationship often holds when X is measured 'before' Y in some sense. Heights of fathers and sons The scatterplot below describes the heights inches of a randomly selected group of 60 men at age 18 and their fathers' heights at the same age.
Although this is not experimental data, the fathers reached 18 years of age before their sons and the sons' heights could not have any influence on the heights of their fathers.
