Accuracy is best defined as

• the degree to which a measurement conforms to the correct value
• the average of multiple measurements
• the range of possible values
• the precision of a measurement

The scientific method is

• A way to predict the weather

• a method for cooking food
• a systematic process for investigating phenomena and acquiring knowledge

• a technique for artistic expression

A physical pendulum is

• A pendulum with the mass located at the end

• A pendulum with the mass spread throughout

• A pendulum with a period of exactly one second

• A pendulum with a length greater than 1 m

A simple pendulum is

• A pendulum with the mass located at the end

• A pendulum with the mass spread throughout

• A pendulum with a period of exactly one second

• A pendulum with a length greater than 1 m

In a lab the dependent variable is

• the variable that is measured or tested in an experiment
• the variable that is not affected by other variables
• the variable that is controlled by the experimenter
• the variable that remains constant during an experiment

Precision is

• the accuracy of a single measurement

• the variability of measurements over time
• the average of all measurements taken
• results being close together

In a lab an independent variable is

• the variable that is manipulated or changed by the researcher
• the variable that remains constant during the experiment
• the outcome measured in response to changes
• the variable that is observed and recorded by the researcher

Quantitative measurements are

• Qualitative descriptions of feelings.
• Numerical values representing quantities.
• Random guesses about numbers.
• Visual representations of data.

Qualitative measurements are

• numerical evaluations of data
• statistical analyses of trends
• descriptive assessments of qualities or characteristics
• numerical comparisons of values

In a lab constants are

• Constants can vary during experiments

• Constants are optional parameters in experiments.
• Constants are only used in theoretical calculations.
• Constants are fixed values that remain unchanged in experiments.
