If an experiment gives about the same result every time it is performed then its results are A. precise. B. accurate. C. reproducible. D. all of these?
If an experiment gives about the same result every time it is performed, its results are A. precise. Precision refers to the consistency of results across multiple trials. While accuracy pertains to how close the results are to the true value, reproducibility relates to the ability of the experiment to yield the same results under the same conditions. Therefore, the correct answer is A. precise.
How do you experiment in science?
Experimentation in science is done following strict scientific protocols. A basic approach is to first form a hypothesis, which is simply a good guess of what will happen in the experiment. After the experiment you examines the data and compare them with the hypothesis. You then comment on how they may or may not match, and then you could publish the results. It is important that the method of how you conducted the experiment and what that was used is included in the report, so that others might try to duplicate your results. If other scientists do the same experiment and get the same results as you did, your report is then strengthened, and it will therefor gain a higher value of credulity.
What are the 3 variables in science?
dependent variable; this is the factor in a experiment that when manipulated by independent variables it changes. it is also known as a controlled variable independent variables or manipulated variable; the factor in a experiment that is deliberately manipulated responding variable; the factor you have to measure to get the results or you will not know the value of the variable
What is repeating an experiment called?
If I am understanding the question correctly, I can give a simple explanaiton to the reason for repetition of an experiment. In any good scientific method process, it is the ultimate responsibility that the results of such experimentation can contain the following two factors: RELIABILITY: the ability for any other individual to perform the same experimentation under the same conditions and achieve the same result is critical. VALIDITY: the ability once the reliabilty has been established, the results can be considered without any futher "re-invention of the wheel" valid and no additional testing or experimentation is needed. (REMEMBER-- results are only valid if the same procedure over and over has yeilded the same results under the same conditions.
What is a factor that cannot be changed during a experiment?
A constant factor is one maintained unchanged throughout an experiment so that it does not affect the outcome. These are also referred to as controlled variables.
How well the results of an experiment agree with the accepted value's.?
cell
What describes how well the results of an experiment agree with the standard value?
Accuracy.
Can you calculate percent error of the results from an experiment?
(experimental value - accepted value)/accepted value x 100 This is an absolute value, so ignore any minus sign.
Does your value of R agree with the accepted value within your uncertainty limits?
Yes, if the value of R falls within the uncertainty limits, it agrees with the accepted value. Uncertainty limits are used to account for variations in measurements and ensure that the true value falls within a specified range. Comparing the value of R to the accepted value within the uncertainty limits helps determine the accuracy of the measurement.
What is Calculated by subtracting the experimental value from the accepted value dividing the difference by the accepted value then multiplying by 100?
The process you described calculates the percent error in an experiment. It quantifies the difference between an experimental value and an accepted or theoretical value, providing insight into the accuracy of the experimental results. The formula is: Percent Error = (\frac{(\text{Accepted Value} - \text{Experimental Value})}{\text{Accepted Value}} \times 100). This metric is commonly used in scientific experiments to assess the reliability of measurements.
The difference between an accepted value and an experimental value is called?
In science, and most specifically chemistry, the accepted value denotes a value of a substance accepted by almost all scientists and the experimental value denotes the value of a substance's properties found in a localized lab.
What are the possible sources of error in this experiment value data is not close to accepted and true value?
Not enough information
What is the conclusion of a density?
The conclusion of a density experiment would typically involve comparing the calculated density value to a known or accepted value to determine the accuracy of the measurement. If the calculated density is close to the accepted value, it indicates that the experiment was successful and the substance was identified correctly.
What does accepted value mean?
An accepted value is one that is obtained from a respected reference source and is one that has been validated by multiple experiments to be correct. This differs from your experimental value in that the latter is what you actually obtain from your experiment - which can vary depending on your level of skill and the materials used.
Which term describes how close measurements are to the actual value?
Accuracy describes how close measurements are to the actual value. It is a measure of how well the results agree with the true value of the quantity being measured.
Why is a bad word a bad word?
Because it has an accepted social value. It's considered bad because most people agree that it's bad.
