Answer:
c) the emotional or neutral word list
Explanation:
In research, we usually have two different types of variables:
- The independent variable is the one that the researchers can control and that will have an effect on another variable.
- The dependent variable is the one that cannot be control and that is affected by the independent variable. Researchers observe this variable to see how it changes. This is the variable that will be tested or measured.
In other words, the independent variable has an effect on another one and it can actually be controlled by researchers.
In this example, Dr. Kang wants to examine the effects of emotion on memory. In other words, how emotions affect memory. He proceeds to hand a list of words with very emotional content to a group of subjects and a list of neutral words to another group and then measures how many words each group is able to remember. We can see that he thinks emotional words will have an EFFECT on emotion. Also, he can control this variable by handing different lists (emotional or neutral words) to each group. Therefore, this is the independent variable. ( c. the emotional or neutral word list)
The primary cost component for American scheduled airlines is fuel, which accounts for the majority of operational expenses.
<h3>
What are fixed and variable costs for an airline?</h3>
In contrast to variable costs, which change over time, fixed expenses remain the same. Variable costs, which include things like fuel, oil, maintenance, landing fees, etc., on the other hand, are subject to change. The fixed costs do not change regardless of how much time you spend flying your aircraft.
<h3>
What are aircraft direct operating costs?</h3>
The term "direct operating cost" (DOC) refers to expenses that are directly connected to running a flight, such as flight attendant pay, aircraft fuel and oil, lease rental or depreciation, maintenance costs, insurance premiums, ground handling, navigational fees, landing and parking fees, and in-flight catering services.
