How does the addition of a constant and multiplication by a constant affect the arithmetic mean?
If you add the same constant to each element of a sample then the mean of this collection of values will be the mean of the original sample plus the constant. If you multiply each element of a sample by a constant then the mean of this collection of values will be the mean of the original sample multiplied by the constant.
How does sample size affect the validity of an experiment?
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
How does sample size affect the margin of error?
The larger the sample size, the smaller the margin of error.
Explain the differences between a sample and a population?
A sample consists of a small portion of data when a population is taken from a large amount.
What is a cluster sample example?

How does halving the sample affect the density?
Not at all. The density remains the same.
How does halving a sample affect the weight of the sample?
If the sample is homogeneous, then half of its volume has half of its mass and half of its weight.
The color of light given off when a sample is heated corresponds to?
heated of the element heat absorbed by the sample amount of energy added to the sample energy difference between the ground state and exited states of an element.
What effect does the amount of the sample of a substance affect its density?
it has no effect. density of a substance is the same no matter the size or shape of the sample.
How does the addition of a constant and multiplication by a constant affect the arithmetic mean?
If you add the same constant to each element of a sample then the mean of this collection of values will be the mean of the original sample plus the constant. If you multiply each element of a sample by a constant then the mean of this collection of values will be the mean of the original sample multiplied by the constant.
Is it true or false that characteristic properties of elements do not depend on the amount of material present in a sample of the element?
It is true.
How much time is needed for half the amount of the sample of an element to decay?
The half-life has a specific value for each isotope.
What is the macroscopic sample element of zinc?
The chemical symbol of zinc is Zn; "macroscopic sample element" is a strange formulation in chemistry.
What three types of information are needed on order to find an empirical formula from percentage composition data?
· Assume that you have 100.0 g sample of the compound · Calculate the amount of each element in the sample · Convert the mass composition of each element to a composition in moles by dividing by the appropriate molar mass
Is a sample of pure solid chromium is homogeneous?
A sample of any pure element is homogeneous.
How does increasing the sample size affect the sample error of the mean?
It should reduce the sample error.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
