An experiment is designed to compare the differences in health outcomes between people who are visited in the hospital by therapy cats and people who are not. Which of these is the independent variabl?
The independent variable in this experiment is whether the patients are visited in the hospital by therapy cats or not. This variable is manipulated by the researchers to observe its effect on the health outcomes of the patients.
What does the experiment in the scientific method mean?
In the scientific method, the experiment is a controlled procedure designed to test a hypothesis by collecting data. It involves manipulating one variable while keeping others constant to observe the effects and draw conclusions. The results of the experiment help determine the validity of the hypothesis.
What was Zimbardo's role in the Stanford prison experiment?
Philip Zimbardo was the lead researcher in the Stanford prison experiment, which he designed and supervised. He played a significant role in shaping the study's methodology and overseeing its implementation.
What research methods can show cause and effect?
Experimental research methods, such as randomized controlled trials, are designed to establish cause and effect relationships by manipulating one or more variables and observing the effect on another variable. These methods involve random assignment of participants to different conditions to ensure that any observed effects can be attributed to the manipulation of the independent variable. Longitudinal studies that track changes over time can also provide evidence of cause and effect relationships, although they may be subject to confounding variables.
What does the phrase social experiment mean?
A social experiment is a research method where individuals or groups are exposed to certain conditions to observe how they behave or respond. These experiments are designed to study social phenomena and interactions in a controlled setting to draw conclusions about human behavior.
What dose controlled experiment mean?
this is an experiment that only one varible is manipulated at a time
How many variables do you investigate in a controlled experiment?
There are complex models that allow researchers to study several variables if the experiment is carefully designed and very carefully carried out. These models can show whether a variety of variable interactions occur, and if that is your focus then these models are good. But the best experiments investigate a small number of variables, as few as one.

What question was spallazanis experiment designed to answer?
Spallanzani's experiment was designed to disprove the spontaneous generation of microbes in the air.
Does an observational study or a designed experiment allow the researcher to claim causation between and explanatory variable and a response variable?
designed experiment
The aim of an experiment should be in the form of a what?
An experiment should be designed to answer a specific question.
Why in the experiment the two known resistance are kept equal?
It depends on what the experiment is designed to do!
Is the independent variable the thing you change?
Yes The independent variable is also known as the manipulated variable. In an experiment where you need to test different objects, the independent variable would be the different objects.
How many variables does a properly designed experiment have?
One
What is designed experiment in statistics?
They are experiments which are designed in such a way as to provided maximum information about the effects on the dependent variable of explanatory (independent) variables, separately as well as their interactions, with the smallest number of experimental subjects. Latin squares and Graeco-Latin squares are some of the better known examples.
Researchers performing a well-designed experiment should base their conclusions on?
data from repeated trials of the experiment
Which best explains why replicating an experiment should be done by someone other than the person who original did the experiment?
It shows that the experiment is designed properly.
