What are the Different ways to present experimental data?
different kind experiment data present bar graph
What is the name for an experiment in which a control group is compared with an experimental group?
The control group.
Why is it important to identify as much variables as possible in an experiment?
Accounting for errors in an experiment will determine the validity and reliability to the experiment. This, in turn, will either support the experimental results by accepting the null hypothesis or to discard the experimental results by rejecting the null hypothesis
The factor by which an experimental group differs?
In an experimental design comparing two groups in which one group gets one treatment and another group gets a second treatment, the experimental group is the group with the "different" treatment. The control is the "usual" treatment; the experimental group gets the "new" treatment. Of course, things get complicated with more complicated "experiments."
What is a factor in a experiment that you measure to gather results?
It is a variable. The independent (manipulated) variable is the factor that is different between the control and experimental groups. The dependent variable is the difference resulting from the independent variable. The controlled variables are the factors that are not changed in the experiment between the control and experimental groups.
How do a control sample and an experimental sample differ from each other?
A control sample is the experiment under regular conditions. An experimental sample is the experiment in which different variables are changed.
What principle experimental design reduces errors due to chance by repeating an experiment on different subjects under different conditions?
Replication
What are the 2 different groups in a scientific experiment?
experimental and control
What is experimental variation?
Experimental variation refers to the differences in outcomes or results that are observed between different trials or groups within an experiment. These variations can arise due to factors such as measurement errors, environmental conditions, or random chance. Minimizing experimental variation is important to ensure the reliability and validity of the experimental results.
What is the different between a control group and an experimental group in an experiment?
The control group does not change, while the experimental group is the variable you are changing.
What are the Different ways to present experimental data?
different kind experiment data present bar graph
Why are the results for theoretical and experimental probability different?
The theoretical model does not accurately reflect the experiment.
What is the name for an experiment in which a control group is compared with an experimental group?
The control group.
Why densities calculated in experiments may be different from accepted densities?
Differences in experimental densities could be due to measurement errors, experimental conditions not matching standard conditions, presence of impurities in the sample, or incomplete drying of the sample. Other factors include variations in temperature, pressure, or atmospheric conditions during the experiment, all of which can affect the accuracy of density measurements.
Is it possible for two separate groups to conduct the same experiment to determine an experimental probability and get different results?
Yes
Use the word group's in a sentence?
There are two different types of groups in the experiment, a control group and a experimental group
What is the experimental probability of rolling a 3?
The experimental probability of anything cannot be answered without doing it, because that is what experimental probability is - the probability that results from conducting an experiment, a posteri. This is different than theoretical probability, which can be computed a priori. For instance, the theoretical probability of rolling a 3 is 1 in 6, or about 0.1667, but the experimental probability changes every time you run the experiment
