What else can I help you with?
How many controls can you have in an experiment?
The number of controls in an experiment can vary depending on the study design and objectives. Typically, experiments include at least one control group to compare against the experimental group, but researchers may include multiple controls to account for various factors, such as environmental conditions or specific variables. Ultimately, the number of controls should be sufficient to ensure the reliability and validity of the results without complicating the experiment unnecessarily.
After the scientist makes a hypothesis they perform a to collect data?
the answer is the scientist designs a scientific inquiry
A scientist performs an experiment The results of the experiment disagree with a scientific theory The scientist repeats the experiment several times and gets the same results The scientist then?
The scientific theory should be changed.
A scientist does an experiment The results of the experiment disagree with a major scientific theory What should the scientist do?
Analyze the experiment to decide whether the results were flawed.
Why do you have controls in an experiment?
The controls shows the normal state of affairs, so as to allow a comparison with the experiment results, and to help ascertain that the results obtained were due to the factors tested in the experiment, and not a natural occurence/incidence. Having controls in an experiment can thus be said to validate the experiment itself.
What is the name of the variable that the scientist controls in an experiment?
Control group or mean- it is the point to which variances will be compared
What variable does the scientist change in an experiment?
The variable that the scientist changes in an experiment is called the independent variable. This is the factor that the scientist manipulates or controls to observe its effects on the dependent variable, which is the factor being measured or observed.
What is a manipulating variable?
A manipulative variable is something that you will keep the same.
What is a part of an experiment that can change?
An independent variable is a part of an experiment that can change. This is the variable that the scientist manipulates or controls in order to observe its effect on the dependent variable.
How can a scientist improve the accuracy of the experiment?
A scientist can improve the accuracy of an experiment by carefully designing the study, ensuring precise measurement techniques, reducing errors through proper controls, replicating the experiment to check results consistency, and analyzing data rigorously to draw reliable conclusions.

What options does a scientist have if experiment does not support hypothesis?
a scientist can do another experiment or change their hypothesis.

What variable that a scientist changes when conducting an experiment is called the manipulated variable?
The manipulated variable, also known as the independent variable, is the factor that a scientist intentionally changes or controls in an experiment to observe its effect on the dependent variable. This variable is crucial for testing hypotheses and determining cause-and-effect relationships. By altering the manipulated variable, researchers can gather data and draw conclusions about how it influences the outcome of the experiment.
