the internal validity is still manipulated by the researcher and the DV is measured.
The DV is a variable that is being measured/observed, whereas the IV is a variable that is altered to see how it impacts something else. The term "dependent" refers to the idea that the IV will have an impact on the DV.
<h3>What parallels exist between studies conducted in a lab and those conducted in the field?</h3>
Since experiments are the only way to reliably establish causality, laboratory and field experiments are comparable in that they are both helpful in determining cause and effect. Furthermore, because there is a high level of control over confounding variables, the two experiment designs have the potential to have high internal validity.

It gives electrons because they are both oppositely charged
Answer: The correct answer is : Friendly and parasympathetic. Somatic motor response
Explanation: Hypothalamic neurons, especially within the lateral hypothalamus, respond to sensory signals by inciting an appropriate somatic motor behavioral response. These motor responses influence the somatic motor system, producing motivated behavior. The integration of the sympathetic and the parasympathetic to the emotional expression is mediated by the hypolatam.
In some research, the researchers are not able to use random assignments to divide participants among groups. Instead, they compare preexisting groups, which results in a quasi-experimental design.
Random assignments are those which are given as a matter of chance to ensure fairness and equal opportunity for all participants. Here participants forming multiple groups are with similar characteristics. So all groups are the same at the start of the experiment.
A quasi-experimental design applies a non-random method, and subjects are assigned to preexisting groups. There are some situations where true experiments can't be used for practical reasons. In such cases, a quasi-experimental design is a suitable tool.
