To increase our survival chance.
Explanation:
In order to survive in the harsh environment, Humans generally need to do 2 things : fulfill our basic needs and defend ourselves from external threats.
Both of them would be much easier if Humans are working together in a group.
For example, during hunter/gatherer eras, catching animals that can run faster than humans will be much easier if we have teammates to surround the prey rather than working alone.
On top that, being in a group also provide better protection from the attacks of wild animals or other humans. This is why human creatures get transformed into a social being.
Answer:
confounding variable; lowered.
Explanation:
In the field of statistical analysis, a <u>confounding variable</u> is one that influences both the independent variable and the dependent variable. When an experimented is designed, the researcher wants to study the effect the independent variable has on the dependent variable. However, if there's a third variable that can influence them, it can cause a spurious correlation.
The psychologist wanted to test the effects using the new computer program (independent variable) had in helping students learn math (dependent variable). But when she divided the group in two, separating them by gender, she introduced a third variable (confounding variable) that wasn't accounted for when designing the experiment and that can influence either variable. <u>Because of this, the internal validity of the study has been </u><u>lowered</u><u>.</u>
