5 Ways U.S. Aircraft Carriers Will Soon Be More Lethal. Far from being obsolete, future aircraft carriers will pack a much more lethal punch. HMS Furious, the first real aircraft carrier, entered service in early 1918. A converted cruiser, she displaced about 20,000 tons, and flew about half a dozen Sopwith Camels, an aircraft with a range of about 150 miles and a weapons payload just short of 100 pounds. Twenty-five years later, Furious could carry 36 aircraft, ranging at least twice as far with weapon loads of around 2,000 pounds.
Dependent and Independent Variables. The key to designing any experiment is to look at what research variables could affect the outcome. There are many types of variable but the most important, for the vast majority of research methods, are the independent and dependent variables. A researcher must determine which variable needs to be manipulated to generate quantifiable results. The independent variable is the core of the experiment and is isolated and manipulated by the researcher. The dependent variable is the measurable outcome of this manipulation, the results of the experimental design.
An independent variable is a variable that is manipulated to determine the value of a dependent variable s.
