4. VARIABLES
Variable is something that can be changed.
Independent variable:- A researcher wants to determine if the color of an
office has any effect on worker productivity. In an experiment, one group
performs a task in a yellow room while another performs the same task in a
blue room. In this example, the color of the office is the independent
variable.
Dependent variable:- Researchers want to discover if listening to classical
music helps students earn better grades on a math exam. In this example,
the scores on the math exams are the dependent variable.
5. Personality And Heredity
If we take into consideration personality and heredity we can say that personality is the dependent
variable while heredity will be the independent variable. According to the heredity approach it has been
argued that the ultimate explanation of an individuals personality is the molecular structure of the genes
located in the chromosomes.
For e.g., as per several researches it has been inferred that if two identical twins which were raised
separately and put in different households ; they tend to have behavioral similarity and a lot in common
which can be associated with genetic factors, i.e., inherited from their parents.
