The aim of an experiment is
the purpose or objective
changed by the experimenter
measured by the experimenter
kept constant by the experimenter
The independent variable of an experiment is
the purpose or objective
changed by the experimenter
measured by the experimenter
kept constant by the experimenter
The dependent variable of an experiment is
the purpose or objective
changed by the experimenter
measured by the experimenter
kept constant by the experimenter
The controlled variable(s) of an experiment is
the purpose or objective
changed by the experimenter
measured by the experimenter
kept constant by the experimenter
The hypothesis of an experiment is
the purpose or objective
a possible outcome of the experiment
measured by the experimenter
is always supported
Quantitative analysis is
non-numerical data collected during an experiment
data which provides a numerical value collected during an experiment
a technique that determines the composition of a sample
a technique that identifies the amount of a substance present
Qualitative analysis is
non-numerical data collected during an experiment
data which provides a numerical value collected during an experiment
a technique that determines the composition of a sample
a technique that identifies the amount of a substance present

Quantitative data is

primary data is
non-numerical data collected during an experiment
data which provides a numerical value collected during an experiment
collected first hand by the experimenter
collected by other sources
Accuracy is
the difference between true value and measured value
how close measured values are to the true value
how close measured values are to each other
the level of doubt around the data measured
Errors are
the difference between true value and measured value
how close measured values are to the true value
how close measured values are to each other
the level of doubt around the data measured
Precision is
the difference between true value and measured value
how close measured values are to the true value
how close measured values are to each other
the level of doubt around the data measured
Uncertainty is
the difference between true value and measured value
how close measured values are to the true value
how close measured values are to each other
the level of doubt around the data measured
Systematic error is
the difference between the average of a large set of measurements and the true value
a result of a mistake or misinterpretation of method or reading by the experimenter
error in measurement that differs in proportion each time. Usually a 'One off' error.
error in measurement by the same proportion and direction each time. A constant bias in the measurements.
Random error is
the difference between the average of a large set of measurements and the true value
a result of a mistake or misinterpretation of method or reading by the experimenter
error in measurement that differs in proportion each time. Usually a 'One off' error.
error in measurement by the same proportion and direction each time. A constant bias in the measurements.
Personal error is
the difference between the average of a large set of measurements and the true value
a result of a mistake or misinterpretation of method or reading by the experimenter
error in measurement that differs in proportion each time. Usually a 'One off' error.
error in measurement by the same proportion and direction each time. A constant bias in the measurements.
A bias is
the difference between the average of a large set of measurements and the true value
a result of a mistake or misinterpretation of method or reading by the experimenter
error in measurement that differs in proportion each time. Usually a 'One off' error.
error in measurement by the same proportion and direction each time. A constant bias in the measurements.
Validity is
the difference between the average of a large set of measurements and the true value
a result of a mistake or misinterpretation of method or reading by the experimenter
whether or not an experiment is testing the aim and hypothesis of the experiment
error in measurement by the same proportion and direction each time. A constant bias in the measurements.
Reproducibility is
refers to the closeness of of agreement between independent results obtained by the same operator, same apparatus or laboratory
refers to the closeness of of agreement between independent results obtained by different operators, different apparatus or laboratory
refers to the closeness of of agreement between independent results obtained by the same operator, different apparatus or laboratory
refers to the closeness of of agreement between independent results obtained by different operators, same apparatus or laboratory
Repeatability is
refers to the closeness of of agreement between independent results obtained by the same operator, same apparatus or laboratory
refers to the closeness of of agreement between independent results obtained by different operators, different apparatus or laboratory
refers to the closeness of of agreement between independent results obtained by the same operator, different apparatus or laboratory
refers to the closeness of of agreement between independent results obtained by different operators, same apparatus or laboratory
A control is
an identical experiment conducted at the same time but doesn't have independent variable changed
an identical experiment conducted at the same time but has more than one independent variable
an identical experiment conducted at a different time but doesn't have independent variable changed
an identical experiment conducted at a different time but has more than one independent variable
An outlier is
a result of bias
a random error
should be ignored
a reading that may lie a long way from others
