The sample size was 3,020 persons.

The Board's sample review showed that the field offices had properly verified all the sampled subproject monitoring reports.

Potential problems include total sample size, small sample size per country, too few observations for each participant, and psychological effects of using a stopwatch.

In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population are less likely to be included than others.

However, care is required to avoid cooking the specimen.

The scattering pattern contains the information on the structure of the sample.

The nature of the separation depends on the treatment of the sample and the nature of the gel.

After any necessary dissections take place, the specimen is then placed in a bath of acetone.

Gel electrophoresis The proteins of the sample are separated using gel electrophoresis.

Once the sample starts to boil, heating is stopped, and the temperature starts to fall.

This specimen's skin was almost completely preserved in the form of impressions.

The quality of the sample is sufficient for research on molecular biology.

For example, if half of the marked individuals were recaptured, it would be assumed that half of the total population was included in the second sample.

The sample covered 88 per cent of the population in developing countries and countries with economies in transition.

Statistical tables are then used to derive the concentration of organisms in the original sample.

If the sample is a mixture containing N components, the molar volume is calculated using formula_2.

The liquid traps a sample of gas in the cylinder, and the graduation allows the volume of the gas to be measured.

An explosimeter is a gas detector which is used to measure the amount of combustible gases present in a sample.

Their sample included countries in Latin America and Asian countries beyond Japan.

So if we can tell the gender of the shark before we sample it, we can tell the geneticist this was taken from a male or a female.

So, they're all floating around in solution, and to look at them, you have to get them on a surface where they stick.

In the branch in which the sample radiates, it sets off a trigger that releases poison and Schrödinger is dead.

Indeed, stress is defined as the force divided by the area at the start of the experiment.

The temperature at which the liquid sample is sucked into the sealed capillary is the boiling point of the sample.

A relatively small sample of the population may have been measured, which makes it uncertain whether this sample accurately represents the entire population.

The van der Waals forces, which are strongest from 1 nm to 10 nm above the surface, or any other long range force that extends above the surface acts to decrease the resonance frequency of the cantilever.

One major challenge is various factors that affect the sample and raise the margin of error for the analysis.

The source of this color is ISCC NBS Dictionary of Color Names (1955) Color Sample of Wine (color sample 16).

We've just connected the dots. What we need to do is increase our sample size by an order of magnitude or more hundreds of thousands of DNA samples from people all over the world.

The target groups were three age groups 11, 13 and 15 years old and the sample covered a total of 5,134 pupils.

The TLC plate is then placed in the chamber so that the spot(s) of the sample do not touch the surface of the eluent in the chamber, and the lid is closed.

When this tissue is fixed and stained to be better viewed under a microscope, the lipid is usually dissolved by the solvents used to prepare the sample.

In four of the sampled cases, no UNHCR office acted upon disclaimers of opinion.

A reasonable generalization from this rather small sample would be that prosperous and constitutional democracies tend to live in peace with each other.

formula_19and formula_20It would seem that the sample mean is a better estimator since its variance is lower for every N 1.

In the third step, the specimen is then placed in a bath of liquid polymer, such as silicone rubber, polyester or epoxy resin.

The minimum number of samples required is two an initial sample after the isotopes have reached equilibrium in the body, and a second sample some time later.

Sadly, results are not much better in reading ability again, the Latin American nations were at the bottom of the 40 country sample.

The sample is stirred into the Ludox solution and left to settle for 40 min, after which the meiofauna are filtered out.

These enrichments (δ) represent the ratio of heavy isotope to light isotope in the sample over the ratio of a standard.

The target groups of this research were two age groups, averaging 11.5 and 13.5 years old, while the sample comprised a total of 3,200 pupils.

Buffy coat may sometimes be green if there are large amounts of neutrophils in the sample, due to the heme containing enzyme myeloperoxidase that they produce.

Pay as you throw (PAYT)(also called trash metering, unit pricing, variable rate pricing, or user pay) is a usage pricing model for disposing of municipal solid waste.

It was found that, amongst the total sample, 4.8 were cybervictims only, 7.4 were cyberbullies only, and 5.4 were cyberbully victims.

This implies that, in the second sample, the proportion of marked individuals that are caught (formula_2) should equal the proportion of the total population that is caught (formula_3).
