A) You are conducting an experiment on the effect of reward on people's persistence in solving difficult math problems. In one condition, participants are told they will receive $20 for completing all the math problems. In the other condition, participants are told they will receive a chocolate (worth 5 cents) for completing all the math problems. The independent variable is _________________ and a sensible dependent variable would be _______________. a. pre-existing math ability; satisfaction with reward b. type of reward promised; time spent on math problems c. difficulty of math problems; satisfaction with reward d. difficulty of math problems; time spent on math problems

Gaining knowledge by science is a merger of rationalism and empiricism. This means:
|
The systematic observation and collection of data, coupled with the formulation of hypotheses and theories. |
