Chapter 6 Flashcards
When the same procedure is applied to a very large number of individual errors, a bell-shaped curve results. Such a plot is called a?
Gaussian curve or a normal error curve
set of replicate measurements is the difference between the
highest and lowest result.
Spread
It is a representation of the distribution of numerical data.
Histogram
A curve that shows the symmetrical distribution of data around the mean of
an infinite set of data
Gaussian, or normal error curve
A collection of all measurements of interest to the experimenter
population
It is a subset of measurements selected
from the population
Sample
It refers to quantities such as m and s that define a population or distribution.
Parameter
What do you call a data values such as x?
Variables
measure of the precision of the population
population standard deviation o
The standard deviation of each mean is known as
Standard Error of the mean
It is equal to the square
of the standard deviation.
variance, s2
It is the percent relative standard deviation
coefficient of variation, CV
another term that is sometimes used to describe the precision
of a set of replicate results
spread, or range, w,
The ______ in a number are all of the certain digits plus the first uncertain digit.
significant figures
