Accuracy

Accuracy (Medicine)

Accuracy (pronounced: ak-yuh-ruh-see) in the field of medicine refers to the degree to which a measurement, or an estimate based on measurements, represents the true value of the attribute that is being measured. In other words, it is the closeness of a measured value to a standard or known value.

Etymology

The term 'accuracy' is derived from the Latin word 'accuratus', which means 'done with care'.

• Precision (Medicine): Precision is the degree to which repeated measurements under unchanged conditions show the same results. While accuracy is about the closeness of the measured value to the true value, precision is about the closeness of two or more measurements to each other.
• Reliability (Medicine): Reliability refers to the consistency of a measure. A test is considered reliable if we get the same result repeatedly.
• Validity (Medicine): Validity is the extent to which a concept, conclusion or measurement is well-founded and corresponds accurately to the real world.
