3.2.4 reliability Flashcards
what can result in variation in experimental results
the reliability of measurement methods and inherent variation in the specimens
how can the reliability of measuing instruments or procedures be determined
by repeated measurements or readings of an individual datum point
what does the variation observed when testing the reliability of measuring instruments indicate
the precision of the measurement instrument or procedure but not necessarily its accuracy
how can the natural variation in the biological material being used be determined
by measuring a sample of individuals from the population
what does the mean of repeated measurements give an indication of
the true value being measured
what is the range of values a measure of
the extent of variation in the results
if there is a narrow range of value, is variation low or high
low
when should independent replication be carried out
to produce independent data sets
when can overall results be considered reliable
if they can be achieved consistently
what should you do with independent data sets to determine the reliability of their results
compare them
