Describe research methodologies that involve manipulation of an independent variable. What relationship does the dependent variable have to the independent variable? Include an explanation of experimental group, control condition, and random assignment
FIll in the blank with correct word.
Answer: The independent variable is the factor manipulated by the experimenter. The dependent variable is that which the experimenter measures. The hypothesis states that the dependent variable will be affected by the independent variable in some way. The experimental group is the group that receives the treatment condition. The control group does not. Random assignment has as its goal elimination of confounding variables to the extent possible, since they will vary equally across groups. Include terms such as operational definition and random sampling.
