How do you differentiate between accuracy and precision of data?

So accuracy is how close the mean is to the true value. Precision is how close all your values are to each other. If you have repeatable results you will see this straight away. Spiking samples with known amounts is a great way to find out if you have as much as you think you have i.e. checking the accuracy

Would The precision of a graph may be lost when the information is transferred from a table?
In general it could - particularly if the precision of the scale is not matched by the accuracy of the data in the table.
What is the math tools scientists use when analyzing data?
Mode,range,anomalous data,percent error,mean,precision,meddian,estimate,accuracy,and maybe significant figures
How do you evaluate accuracy and precision?
Accuracy is hitting the same, correct point, sort of like hitting the bulls eye of a target. Precision is less stringent, as long as your data points are clustered together (it's also known as the level of uncertainty or variance), it is deemed precise. Scientifically speaking, experiments have to be both accurate and precise.
How do related tables improve the accuracy of a data in a database?
In short, they do not. Relating tables in a database defines the relationships between the data sets in the different tables and allows the data to be accessed more efficiently, but it does not affect the accuracy of the data entered.
How can you check the accuracy of your data?
No
Compares a measurement to the real or accepted value?
accuracy. precision how closely the group of data are in relation to each other

Do precision and accuracy mean the same thing in science?
Precision and accuracy do not mean the same thing in science. Precision refers to how well experimental data and values agree with each other in multiple tests. Accuracy refers to the correctness of a single measurement. It is determined by comparing the measurement against the true or accepted value.
What is the difference between group and ungroup data?
Q: differentiate between group and ungroup data
How do you differentiate between accuracy and percision of data?
Accuracy is how "correct" your answer is. Precision is how "close" your answer is. If you were to measure the amount of water your cup can hold: An example of accuracy would be rounding numbers to significant figures. Since there are uncertainties in the measurements you take, it would be more correct to use significant figures. An example of precision would be the use of decimal places. Although by using maths you can calculate the exact volume of the cup and give it correct to any number of decimal places, in reality, this is not always the case. You can be precise without being accurate. In the above example, you can give a number with lots of decimal places, but it can be way off the actual answer.
What are the differences between closeness of fit and the strength of relationship?
Closeness of Fit means that statistical models are typically evaluated in terms of how well their output matches data, that is, in terms of model accuracy. A model can match data in several ways, including precision, the absolute "closeness of fit" between model predictions and data.
What is the math tools scientists use when analyzing data?
Mode,range,anomalous data,percent error,mean,precision,meddian,estimate,accuracy,and maybe significant figures
Why is it necessary to take proper measurement?
To collect data, improve accuracy and precision in observations, and eliminate using the phrase "that's close enough."

Definition for scientific accuracy?
Accuracy refers to how close or far a determined experimental value may be from the actual value. This is in distinct contrast to precision, which refers to how close experimental data is grouped together with subsequent repetitions.
Precision refers to?
Precision refers to how close one's results are to each other. Accuracy on the other hand refers to how close one's results are to the true value. Think of a target, precision would be how tight the grouping of the arrows was, while accuracy would be how close one was to the bullseye. To clarify, being precise does not equate to being accurate, because while one might obtain data that are all very close, these data might not be near the true value.
