Accuracy
The degree to which a measurement, or an estimate based on measurements, represents the true value of the attribute that is being measured. In the laboratory accuracy of a test is determined when possible by comparing results from the test in question with results generated from an established reference method.
Conclusion
Summary of how results support or contradict the original hypothesis
Control
In research, control subjects or control procedures permit comparison with experimental results.
Controlled experiment
A procedure done in a controlled environment for the purpose of gathering observations, data, or facts, demonstrating known facts or theories, or testing hypotheses or theories.
Dependent variables
In experiments, a variable that is influenced by or dependent upon changes in the independent variable
Hypothesis
A supposition that appears to explain a group of phenomena and is advanced as a basis for further investigation, a proposition that is subject to proof or to an experimental or statistical test.
Independent variables
A characteristic being measured or observed that is hypothesised to influence another event or manifestation (the dependent variable) within a defined area of relationships under study; that is, the independent variable is not influenced by the event or manifestation, but may cause it or contribute to its variation.
(See: dependent variable)
Observation
An act or the faculty of observing or taking notice: an act of recognising and noting measurement of some magnitude with suitable instruments.
Precision
The quality of being sharply defined or stated; one measure of precision is the number of distinguishable alternatives to a measurement. Reproducibility of a quantifiable result; an indication of the random error.
Prediction
A statement foretelling the possible outcome(s) of an event, process, or experiment. A prediction is based on observations, experience, and scientific reasoning. A guess, on the other hand, is based on conjecture (speculation), chance, and intuition.
Procedure
A series of steps by which a desired result is accomplished.
Principle
A source, or origin; that from which anything proceeds; fundamental substance or energy; primordial substance; ultimate element, or cause.
<chemistry> Any original inherent constituent which characterises a substance, or gives it its essential properties, and which can usually be separated by analysis
Scientific literacy
The knowledge and understanding of scientific concepts and processes required for personal decision-making, participation in civic and cultural affairs, and economic productivity. See more
Validity
The extent to which a measurement, test or study measures what it purports to measure.
Variable
Something that takes on different values that can be measured or counted. If one variable can be controlled exactly (such as the selling price of apples) then it is called an 'independent variable', while the remaining variable (in this case the number of apples bought) is called a 'dependent variable'
Independent variable
A characteristic being measured or observed that is hypothesised to influence another event or manifestation (the dependent variable) within a defined area of relationships under study; that is, the independent variable is not influenced by the event or manifestation, but may cause it or contribute to its variation.
