3.2e - Reliability Flashcards
Variation in experimental results may be due to…
the reliability of measurement methods and/or inherent variation in the specimens
The reliability of measuring instruments or procedures can be determined by…
repeated measurements of readings of an individual datum point
The variation of repeated measurements of readings observed indicates…
the precision of the measurement instrument or procedure but not necessarily its accuracy
The natural variation in the biological material being used can be determined by…
measuring a sample of individuals from the population
The mean of a sample of individuals from the population will give…
an indication of the true value being measured
The range of values is a measure of…
the extent of variation in the results
If there is a narrow range of values then…
variation is low
Independent replication should be carried out to produce…
independent data sets
Overall results can only be considered reliable if…
they can be achieved consistently
Independent data sets should be compared to…
determine the reliability of the results
Repeating experiments as a whole checks…
the reliability of the results
