Working Scientifically Key vocabulary Quiz

What is the definition of "Accuracy" in scientific terms?

• A measurement result is considered accurate if it is judged to be close to the true value.

• These are values in a set of results which are judged not to be part of the variation caused by random uncertainty.

• Marking a scale on a measuring instrument.

• Categoric variables have values that are labels.

What are "Anomalies" in a set of results?

• Values that are judged not to be part of the variation caused by random uncertainty.

• A measurement result that is close to the true value.

• Marking a scale on a measuring instrument.

• Variables that have values that are labels.

What does "Calibration" involve?

• Marking a standard scale on a measuring instrument.

• Values that are judged not to be part of the variation caused by random uncertainty.

• A measurement result that is close to the true value.

• Variables that have values that are labels.

What are "Categoric" variables?

• Variables that have values that are labels.

• Values that are judged not to be part of the variation caused by random uncertainty.

• A measurement result that is close to the true value.

• Marking a scale on a measuring instrument.

What are "Continuous" variables?

• Variables that can be given a magnitude either by counting or by measurement.

• Values that are judged not to be part of the variation caused by random uncertainty.

• A measurement result that is close to the true value.

• Variables that have values that are labels.

What is a "Control" variable?

• A variable which may, in addition to the independent variable, affect the outcome of the investigation.

• A measurement result that is close to the true value.

• Values that are judged not to be part of the variation caused by random uncertainty.

• Variables that have values that are labels.

What is "Data" in scientific terms?

• Information, either qualitative or quantitative, that has been collected.

• A measurement result that is close to the true value.

• Values that are judged not to be part of the variation caused by random uncertainty.

• Variables that have values that are labels.

What is a "Dependent" variable?

• The variable of which the value is measured for each and every change in the independent variable.

• A measurement result that is close to the true value.

• Values that are judged not to be part of the variation caused by random uncertainty.

• Variables that have values that are labels.

What is "Evidence" in scientific terms?

• Data which has been shown to be valid.

• A measurement result that is close to the true value.

• Values that are judged not to be part of the variation caused by random uncertainty.

• Variables that have values that are labels.

What is a "Fair test"?

• A test in which only the independent variable has been allowed to affect the dependent variable.

• A measurement result that is close to the true value.

• Values that are judged not to be part of the variation caused by random uncertainty.

• Variables that have values that are labels.
