The variable (factor) which you measure every time you change the value of the independent variable
A variable (factor) which may affect the results of the investigation and therefore should be kept constant.
The highest and lowest values of the independent variable. These should not be too big or too small.
This is the smallest change in the quantity being measured by a measuring instrument that can be observed. For example ± 1 mm on a 1 metre ruler
A measurement result is considered accurate if it is judged to be close to the true value
A value in a set of results which is seen to be much bigger or smaller than the rest of the values in the set
