Key scientific terminology physics
Cards in this deck (30)
- 1AccuracyA measurement that’s close to the true value
- 2CalibrationMarking a scale on a measuring instrument. Eg putting a thermometer in ice to make it 0
- 3DataInfo either qualitative or quantitative
- 4ErrorSee also uncertainty
- 5Measurement errorThe difference between a measured value and the true value
- 6AnomaliesValues which are not part of the variation. Are caused by random uncertainties
- 7Random errorUnpredictable differences cause by things like human error. A mean can be calculated to reduce this
- 8Systematic errorA measurement that is wrong by the same amount each time
- 9Zero errorA systematic error caused by equipment that isn’t zeroed properly
- 10EvidenceValid data
- 11Fair testWhen the IV has been able to effect the DV
- 12HypothesisA proposal to explain facts and observations
- 13IntervalThe quantity between readings
- 14PrecisionMeasurements in which there is little spread about the mean
- 15PredictionStatement suggesting what happens in the future
- 16RangeMaximum and minimum values of the independent and dependent variables.
- 17RepeatableRepeatable when the experiment is done again with the same equipment and method and the results are the same
- 18ReproducibleIf experiment is repeated by someone else or by using a different method or equipment and obtaining the same results
- 19ResolutionSmallest change in quantity being measured of a measuring instrument that gives a small change in the reading
- 20Sketch graphA line graph that shows a general pattern
- 21True valueValue obtained in the correct measurement
- 22UncertaintyInterval where the true value lies
- 23ValidityIf the experiment answers the question
- 24Valid conclusionConclusion supported by data
- 25VariablesPhysical,chemical and biological quantities or characteristics
- 26Categoric variableLabels eg names of plants
- 27Continuous variablesThey have magnitude found by using counting or by a measurement
- 28ControlCan effect the outcome of the experiment must be kept constant or at least monitored
- 29Dependent variableMeasured for each and every change in the IV
- 30Independent variableVariable that’s values change
