True or false: graphs provide a good visual representation of the relationships between the factors investigated in an experiment?

True

Explanation:

Yes, the graph provides a good visual representation of the relationship between the factors being investigated when there are only two variables being studied at a time. Sometimes a third variable is represented on a negative y-axis which plays a minor role in any one of the factors that may be conveniently represented. Since we can draw only 2-dimensional diagrams on a paper, therefore, graphs are restricted to a couple of variables. The independent variable is usually represented on the x-axis and the dependent variable is represented on the y-axis. Graphs tell us the pattern of variation of a quantity with respect to another.

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
