When can you estimate a population's size when counting individuals in a sample of the population?
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
What happens to the sample size if you increase the standard deviation?
The statistics of the population aren't supposed to depend on the sample size. If they do, that just means that at least one of the samples doesn't accurately represent the population. Maybe both.
What is absolute sample size?
It is the number of elements in the sample. By contrast, the relative sample size is the absolute sample size divided by the population size.
How do you calculate density using a formula?
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
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
Does the density of a substance change depending on how much of it you have?
No. Density is an INTRINSIC property, and as such it does NOT depend on the size of the sample.
Is temperature an extensive or intensive property?
An intensive physical property does not depend on the size of the sample. An example of an intensive physical property is density. An extensive physical property does depend on the size of the sample, such as mass and volume.
Why density is the criteria for purity with respect to chemistry?
Mass and volume are extensive properties, which are dependent upon the size of the sample. A larger sample will have a greater mass and volume than a smaller sample. Density is an intensive property, which does not depend on the size of the sample. Density is a ratio of mass to volume, which does not vary with the size of the sample. The density of a larger sample will be the same as the density of a smaller sample.
Why is the density of a substance independent of sample size?
Density is an intensive quantity which means it is independent of size. This can be seen from the definition of density. Density = mass/volume So if the sample size increases than so does the mass, but the density remains unchanged.
Does the size of a sample change its density determination?
no
Why does the density of a substance not change with the sample size?
The density of a substance does not change with the sample size because density is an intrinsic property of the material, determined by its mass and volume. As you increase the sample size, both the mass and volume of the substance increase proportionally, resulting in no change in density. This relationship is described by the formula density = mass/volume, which remains constant regardless of the amount of the substance being measured.
Is density a extensive property of a substance?
Density is an intrinsic property, not an extensive property of matter. This is because it DOES NOT depend on the size of the sample (amount). The density of a small piece of matter is the same as the density of a larger piece of that same matter.
Can anyone give an ENGLISH meaning for Density?
Well it's kind of hard since Density is a MATHEMATICAL concept, not an ENGLISH concept. Oversimplifcation: Density is a comparison between how much a sample of something weighs compared to its size. If a small size sample is heavy, then it has high Density. If a large size sample is light, then it has low Density.
When can you estimate a population's size when counting individuals in a sample of the population?
You can estimate a population's size when counting individuals if the density in a sample is greater than the population density.
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 heavy is pine?
it actually depend on the sample size.
Does the density of a mineral depend on the size on the mineral.?
No, it doesn't.
