in the double stuffed oreo experiment, what is the positive control of the experiment and what is the negative control of the experimentthank you so much! :)?
In the double stuffed Oreo experiment, the positive control would be the regular Oreo cookie with no added cream. This is because it represents the expected outcome or normal condition, and can be used as a reference point to compare the results of the other cookies with double the cream filling.
The negative control in this experiment would be a cookie that is not an Oreo, such as a plain vanilla cookie or a cracker. This is because it represents a scenario where no effect is expected or the intervention being tested is not applicable. It can be used to ensure that any observed differences in the experimental groups are due to the intervention being tested (in this case, the amount of cream filling in the Oreo cookie) and not due to some other factor, such as the type of cookie being used.

What is the difference between positive and negative control in an experiment?
In an experiment, a positive control is used to show that the experiment can detect a specific response, while a negative control is used to show that the experiment does not detect a response when it should not.
Is this a positive or negative control what information is provided by the results?
To determine whether it's a positive or negative control, we need to know the context of the experiment and the expected outcomes. A positive control typically yields a known response, confirming that the experimental setup is functioning correctly, while a negative control should show no response, ensuring that any observed effects are due to the experimental variable. The results from these controls help validate the experiment's reliability and the accuracy of the conclusions drawn. If the results align with expectations, it supports the validity of the experimental design.
In a scientific experiment what is the definition of a variable?
Pretty much as it is in math, something that is undefined, but in Science it needs to be defined or the experiment cant continue. Your variables are basically what you measure, what you change and your control, both positive and negative (one with a 100% percent positive result and another with a 100% negative result)
What does controlled experiment mean in science terms?
All science experiments are performed in a controlled manner which means, there will be a positive control, a negative control and importantly the subject sample(s) who's behavior is not known. The experimental observation must be positive with the positive control sample and negative with the negative control sample, no matter whatever the condition is. Only in this set up the result of a subject (which is the actual unknown experimental sample) would be considered as a faithful result.Any fault or irregularities of the controls will destroy the authenticity of an experiment.
What is the function of a positive control in an experiment?
A positive control is used in an experiment to ensure that the experimental conditions are capable of producing a positive result. It helps validate the experimental setup and serves as a reference point for comparison with the test samples.
What is the negative control in the lactose experiment?
The negative control in the lactose experiment would be a sample that does not contain lactose or the enzyme needed to break down lactose. This control is used to show what would happen if no lactose were present for the enzyme to act on.
Why is there and the importance of having positive and negative controls?
Positive and negative controls are essential in experimental design to validate the results of an experiment. A positive control ensures that the experimental setup can produce a result when the expected outcome occurs, confirming that the methodology is functioning correctly. Conversely, a negative control checks for contamination or false positives by demonstrating that no result should occur under controlled conditions. Together, they help to ensure the reliability and accuracy of the experimental findings.
What are the colours of the positive and the negative terminals of the rheostat?
A rheostat is simply a variable resistor used to control current. It does not have a positive or a negative terminal.
What is the controlled experiment in a science experiment?
The control in a science experiment is the same thing as a constant. It is something that you keep the same the entire experiment. For example if you were testing how various locations affect temperature your constants would be the thermometer you used and the time for measuring the temperature. If you don't have a constant than your experiment results won't be accurate.
Can birth control pills give you a false negative?
Hi, Your question is: Can birth control pills give you a false negative? No. Birth control pills can not give you a false negative or a false positive.
Why is a positive and negative control used for each biochemical test?
Because!
What's a negative control?
A negative control is a control group in an experiment where the variables are not expected to have an effect. It helps researchers to determine if any observed effects are due to the treatment being tested or other factors.
