, _______-_______ _______ showed that even if the underlying distribution is not normally distributed, the
means of the repeated sampled from the distribution would be very nearly normally distributed, and
4
that the larger the sample size, the more closely the distribution of means approximated a normal
distribution
Don't know?
Terms in this set (70)
Normal distribution is also known as ___ ________, and its Z distribution
graph, the normal curve
Normal distribution can be used to represent what? the way frequencies associated with so many naturally occurring events tend to
be distributed
What are the 3 distributions? z, t, F distributions
_________ ________ noted that errors in measurement by Galileo Galilei (errors in measurement by astronomers were symmetric)
astronomers were symmetric and that small errors
occurred with greater frequency than large errors
________ _________ ________, developed the formula for the Carl Friedrich Gauss--(developed the formula for normal distribution)
normal distribution and demonstrated that errors in
measurement fit this distribution
_______-_______ _______ showed that even if the underlying Pierre-Simon Laplace (the means of repeated samples from any distribution
distribution is not normally distributed, the means of the would be very nearly normally distributed)
repeated sampled from the distribution would be very
nearly normally distributed, and that the larger the
sample size, the more closely the distribution of means
approximated a normal distribution
Laplace: repeated samples --> normal distribution--this Central limit theorem
all led to the discovery of the _______ _____ ________
______ ____ _________ made lengthy computations of the Abraham de Moivre (noted as the number of binomial events increased, the
outcome of events and noted that as the number of shape of that distribution approximated a normal distribution)
binomial events, such as a coin flip, increased, the
shape of the distribution approached a very smooth
curve approximating the normal distribution
Normal distribution are said to be_______ ______ normally distributed
Normally distributed means: they tend to be unimodal and symmetrical and appear as a bell-shaped
distribution
