The variable that is measured in an experiment is the variable?

How many strings does a parachute need?
A parachute needs four strings. However, redundancy is best, both for safety and control of the chute. Thus, 16 striings is better, 32 even moreso. Washers around groups of strings cuts down on the likelihood of entanglement. The length of the strings matters, as well (and so does the diameter of the parachute).
. The variable that a scientist changes when conducting an experiment is called the variable.?

Yes. A number of their outrageous claims have been outrightly debunked on other websites. For example, look up Jenny Thompson on Snopes.

Why is a control needed in an experiment?
The control group gives you something to compare the results to. For example, in a medical trial for a new medicine, one group will receive sugar pills. Without this control group, it means nothing if 50% of those treated with the real medicine get better. The control group may have the same results, better results, or worse results. This tells how effective the medicine is. The same is done with any type of experiment.
