DESCRIBE THE CHARACTERISTICS OF AN EXPERIMENT BY: ARIEL C., JAYLEN, JANAI, ARTHUR, DAVID, AND MARS

DEFINITIONS Experiment: is a controlled study conducted to determine the effect varying one or more explanatory variable or f actors has on a response variable. Any combination of the values of the factors is called a treatment. In an experiment, the experimental unit is a person.

A control group is used to compare two different treatments. A Placebo is a medicine that taste, looks, and smells real, but it is fake. This is used to give off the effect of a real medicine.

BLINDING Blinding refers to nondisclosure of the treatment and experimental unit is receiving. The two types of blinding are: Single Blinding and Double Blinding.

Single Blinding experiment is when they don’t know the treatment that they are recienving. Double Blinding experiment is one in which neither of the experimental unit nor the reseacher in contact with the experimental unit knows which treatment the experimental unit is receiving.

EXAMPLE A Researcher education might want to determine if students are doing their homework on an online system do better on an exam then those who do their homework from the text.
