THE DISTRIBUTION OF REPEATED MEASURES Flashcards
experimental data are normally distributed
when replicate measurements exhibit the
bell-shaped distribution
Normal
Distribution
(Gaussian distribution)
It is equally probable that a measurement
will be higher or lower than the mean. The
probability of observing any value decreases
as its distance from the mean increases.
Normal
Distribution
(Gaussian distribution)
frequency plotted against the
logarithm of the concentration
(or other characteristics) gives
a normal distribution curve.
Log-normal
distribution
The estimated range within which the
true value might fall, within a, given
probability as defined by the
experimental mean and the standard
deviation.
CONFIDENCE INTERVAL
range of results around a mean value
that could be explained by random
error
CONFIDENCE INTERVAL
The likelihood that the true value falls
within the range (probability)
CONFIDENCE LEVEL (%)
The extreme values of the confidence interval
