What is the goal of experimental research? - ANSWER-The goal
of experimental research is to isolate the effect of the predictor
variable on the outcome variable. In an experiment, the

the predictor variable (making it independent of everything
else) and measures the outcome.

randomly assigned to one of two groups. One group had
access to a video-based tutorial.
The other group had access to the same information but in a
print version. The students were tested on the material. Grade

endorsed.
A causal relationship was discovered. The students who were
assigned to use
the video-based tutorial scored higher than those who had
been assigned to
, use the print-based
tutorial
