Question

vocabulary: uncertainty in data and representing data | 1) refers to how close a series of measurements are to one another

1. there are two types, systemic errors and random errors systemic errors affect the accuracy of results in a consistent way random errors affect results in unpredictable ways
2. it is the variable that a scientist deliberately changes during an experiment it is plotted on the x - axis
3. it is a visual display of data
4. it is the difference between an experimental value and an accepted value
5. refers to how close a measured value is to an accepted value
6. the variable whose value depends on, or changes in response to, the independent variable it is plotted on the y - axis
7. they include all known digits plus one estimated digit
8. expresses error as a percentage of the accepted value

Explanation:

1. Precision refers to the closeness of a series of measurements to one another.
2. Errors in experiments are of two types - systemic and random with their respective characteristics.
3. The independent variable is deliberately changed by a scientist and plotted on the x - axis.
4. A graph is a visual display of data.
5. Error is the difference between experimental and accepted values.
6. Accuracy is how close a measured value is to an accepted value.
7. The dependent variable depends on the independent variable and is plotted on the y - axis.
8. Significant figures include all known digits plus one estimated digit.
9. Percent error expresses error as a percentage of the accepted value.
