I apologize for the confusion in my previous response. If a controlled experiment is deemed too risky or unethical, a field study may be the best alternative. In a field study, researchers observe and collect data in a real-world setting, without manipulating variables or controlling conditions as they would in a controlled experiment. This type of study allows for more natural and authentic observations, while still providing valuable insights and data.
The scientific method is sometimes seen as more of a cycle than a linear process. Which statement gives a major reason for this? (1 point)
Responses
Developing a hypothesis can sometimes lead to designing an experiment.
Conducting an experiment can sometimes lead to collecting data.
Analyzing data can sometimes lead to developing conclusions.
Sharing conclusions with others can sometimes lead to new questions.

A student records the time it takes for her pet rabbit to make it through a maze to a carrot. In one test, she has the rabbit try to find the carrot at 8:00 AM after eating its first meal of the day. In the other test, the rabbit tries to find the carrot at 8:00 AM without having eaten its first meal of the day.
In this experiment, which variable is the outcome variable?
the time of day when the rabbit starts the maze
the time required to finish the maze
whether the rabbit is hungry or not
whether or not the rabbit finds the carrot
The time required to finish the maze is the outcome variable in this experiment.

It involves collecting data and observations to test ideas.
It is a way of convincing people that certain facts are true.
It is a way of explaining natural phenomena.
It involves continuing to collect data until you get the results you want.

Responses
It is mostly based on logic and explains a small set of observations.
It has many people who disagree with it.
It has not been published in as many journals as other theories.
