When an experiment is replicated How should the results of the two experiments compare quizlet?
When an experiment is replicated, how should the results of the two experiments compare? The results of the first experiment should be less accurate. The results of the second experiment should be less accurate.
Which best explains why replicating an experiment should be done by someone?
Which best explains why replicating an experiment should be done by someone other than the person who originally did the experiment? It shows that the experiment is designed properly. The experiment will be easier to replicate.
Which two characteristic of data always occur together?
The correct answer to the question “Which two characteristics of Data always occur together” is, option (d). High accuracy and good validity. If a measurement is validated that means it’s accurate.
What is meant by reproducibility?
Reproducibility is a major principle of the scientific method. It means that a result obtained by an experiment or observational study should be achieved again with a high degree of agreement when the study is replicated with the same methodology by different researchers.
What does it means if an experiment exhibits reproducibility?
What does it mean if an experiment exhibits reproducibility? The same results are expected each time the experiment is done. It shows that the experiment is designed properly.
Which describes the best approach when conducting a scientific experiments?
Which describes the best approach when conducting a scientific experiment? conduct repeated trials and make sure the experiment can be replicated .
How can the scientist increase confidence in the results?
The scientist can increase the confidence of his result by conducting the repeated trials in order to make sure that the experiment can be replicated. The same result is expected for each time it is done. The reliability is measured in terms of the percentage.
How would you modify the experiment to produce more reliable results?
You can increase the validity of an experiment by controlling more variables, improving measurement technique, increasing randomization to reduce sample bias, blinding the experiment, and adding control or placebo groups.
What is a main reason why the scientific model of atoms is considered a theory rather than a law?
What is a main reason why the scientific model of atoms is considered a theory rather than a law? It has been changed over time. Based on early observations, including those in the table below, scientists proposed that the continents were once together but had drifted apart.
Why would a model be useful?
Models use familiar objects to represent unfamiliar things. Models can help you visualize, or picture in your mind, something that is difficult to see or understand. Models can help scientists communicate their ideas, understand processes, and make predictions.
