Reliability Flashcards
What is variation experimental results due to
The reliability of measurement methods and/or inherent variation in the specimens.
How can variation be influenced
By the precision and accuracy of the repeated measurements
How is reliability of measuring instruments or procedures determined by
By repeated measurements or readings of an individual datum point.
What does the variation observed indicate
The precision of the measurement instrument or procedure but not necessarily its accuracy
The natural variation in biological material being used can be determined by what
By measuring a sample of individuals from the population
What is the range of values a measure of
The extent of variation on the results
When is the variation low
When there is a narrow range
When should independent replication be carried out
To produce independent data sets
What do independent data sets determine when compared
The reliability of the results
When are results considered reliable
If they can be achieve consistently
What does the mean of repeated experiments in biological material give an indication of
The true value being measured
