Experimental Research Designs “A correlational study determines whether or not two variables are correlated. This means to study whether there is an increase or decrease in one variable corresponds to an increase or decrease in the other variable” (Cherry‚ 2012). In most correlation studies there is a relationship between both variables that had a change‚ while in others there wasn’t necessarily causation between the two (Cherry‚ 2012). An experimental design is one in which the researcher manipulates

THE LOGIC OF EXPERIMENTAL DESIGN The randomized comparative experiment is one of the most important ideas in statistics. It is designed to allow us to draw cause-and-effect conclusions. Be sure you understand the logic: • Randomization produces groups of subjects that should be similar in all respects before we apply the treatments. • Comparative design ensures that influences other than the experimental treatments operate equally on all groups. • Therefore‚ differences in the response variable

TRUE EXPERIMENTAL DESIGN DEFINED: This category of design includes more than one purposely created group‚ common measured outcome/s‚ and random assignment. It is regarded as the most accurate form of experimental approach. It proves or disproves a hypothesis mathematically‚ with statistical analysis. Criteria for an experimental design to fit as a true experimental design: The sample groups must be assigned randomly. There must be a viable control group. Only one variable

Earth‚ the planet that is said to have the most resources to sustain life. A planet that allows us as humans to be born in and continue to live in as we age because of its amazing resources. It isn’t blazing in flames like the Sun‚ or composed of rock and ice like Pluto‚ Earth has water‚ trees‚ and rotates around the sun for heat. It is almost as if Earth were tailored when created to fit human need’s‚ we drink water and breathe its oxygen to survive‚ we use its plants for various reasons‚ from eating
