| Define Random Error | An error in a measurement caused by factors that change from one measurement to another |
| What is a measurment | The value taken as the difference between the judgements of two values of a measuring instrument |
| What is a Systematic Error? | A consistent difference between the measured values and true values |
| How would you describe the results for an experimet to be repeatable | The experimenter repeats the experiment and gets consistent results |
| For an experiment to be repeatable what would you say about the results of other experiements | Other experimenters get similar results |
| Define Accuracy in the context of science | Result is close to the true value (accepted value) |
| Define precision in the context of science | Multiple readings are numerically close together |
| Define Resolution in the context of science | The smallest increment of the measuring instrument |
| What is a Reading | The values found from a single judgement when using a piece of equipment |
| Whats absolute uncertainty? | Absolute uncertainty tells you how large the uncertainty of a value is, usually represented as a fraction OR its the range of all the possible values due to the accuracy of the measurement |
| Define the percentage uncertainty | Simple: Absolute uncertanty as a percentage
Descriptive: Absolute uncertainty tells you how large the uncertainty of a value is, usually represented as a percentage OR its the range of all the possible values due to the accuracy of the measurement |
| When adding / subtracting data what mathematical operation is done to the uncertainity, and what type of uncertainity is it? | Add absolute uncertainities |
| When multiplying/ dividing data what mathematical operation is done to the uncertainity, and what type of uncertainity is it? | Add percetage uncertanties |
| When raising to a power, what mathematical operation is done to the uncertainity, and what type of uncertainity is it? | MULTIPLY PERCENTAGE UNCERTAINTY BY POWER |
| How do u calculate the percentage uncertainty of the mean? | ((0.5 X range) / mean) X 100 |
| Define an error | Difference between the measured value and the true value |
| Define uncertainity | Range in which the true value can lie within |
