The term "independent variable" means precisely what it sounds like. It is a variable that is independent of the other factors you are attempting to assess.

<h3>What is independent and Dependent variable?</h3>
  • Dependent variables are so named because their values are explored in an experiment under the assumption or requirement that they are dependent, by some law or rule, on the values of other variables.
  • The group that does not get the new medication being investigated in a clinical trial. This group is compared to the group that receives the new treatment to see if the new treatment is effective.
  • Assume you want to put a new ADHD medicine to the test. One group would be given the new medication, while the other would be given a tablet that looked precisely like the one given to the others, but it would be a placebo.
  • The control group would be the group that receives the placebo. A control group is the "untreated" group with which an experimental group (or treatment group) is contrasted in experimental designs.
  • It is made up of research units that did not receive the treatment whose effect is being studied.

Gelneren [198K]

The common atrium is subdivided into a left and right atrium by an interatrial septum, which consists of two parts: the septum primum and the septum secundum that partially overlap.

What is septum primum and septum secundum?

  • The septum primum, which divides the right from the left, is a structure inside the primitive atrium.
  • In the direction of the endocardial cushions, this septum descends.
  • The foramen primum, a hole in this septum, keeps the blood flowing through the heart.
  • The foramen secundum develops as the foramen primum shrinks in size.

What is the purpose of septum secundum?

  • A muscular flap called the septum secundum plays a significant role in heart growth.
  • It has a semi-lunar form and develops from the atrium's upper wall to the right of the septum primum and ostium secundum.
  • It is crucial for the foramen ovale to close after birth.
