# Small sample size?

Placing a question mark at the end of a phrase does not make it

a sensible question. Try to use a whole sentence to describe what

it is that you want answered.

### What property like volume depends of the size of the sample?

The volume and the mass of sample both depend on the size of the
sample.
A small sample has small volume and small mass, a big sample has
big volume
and big mass. But the ratio of mass to volume is constant
for a pure sample of
a substance, no matter what size the sample is. That ratio is
called the density
of the substance.

### How To get valid results small samples are sufficient?

I will assume the sample is random. In general, the larger the
sample, the smaller the percentage error will be (the difference
between percentages in the sample, and the percentages in the
universe from whence the sample is taken). The percentage error
tends to go down as the square root of the size of the sample.

### Does the standard deviation of x decrease in magnitude as the size of the sample gets smaller?

No. But a small sample will be a less accurate predictor of the
standard deviation of the population due to its size. Another way
of saying this: Small samples have more variability of results,
sometimes estimates are too high and other times too low. As the
sample size gets larger, there's a better chance that your sample
will be close to the actual standard deviation of the
population.

### How does sample size affect the size of your standard error?

The standard error should decrease as the sample size increases.
For larger samples, the standard error is inversely proportional to
the square root of the sample size.
The standard error should decrease as the sample size increases.
For larger samples, the standard error is inversely proportional to
the square root of the sample size.
The standard error should decrease as the sample size increases.
For larger samples, the standard error is inversely proportional to
the square root of the sample size.
The standard error should decrease as the sample size increases.
For larger samples, the standard error is inversely proportional to
