homogeneous sample

In reality, homogeneous samples of HS are difficult to prepare.

The idea was to get a fairly homogeneous sample, to look at housework attitudes in a group of women with similar backgrounds.

Third, though our data were drawn from an intervention study in which no results approached significance, a more clearly homogeneous sample would have been preferable.

Solid solutions and doped compounds have to be annealed in order to produce homogeneous samples.

Similarly, there is no benefit in imaging a truly homogeneous sample, as a single point spectrometer will generate the same spectral information.

Generally, they are developed from relatively small homogeneous samples and data used to develop the charts may have been obtained from inconsistent measuring techniques.

Some of Dr. Wallerstein's conclusions may also turn out to be premature, or unreliable because they come from a small, homogeneous sample.

By comparing the internal structure (of a homogeneous sample, same date & lot code) of electronic components certain types of counterfeit parts can be discovered.

A homogeneous sample (with a regular crystal lattice) would yield a homogeneous intensity distribution in the topograph (a "flat" image).

It was recognised of course that not everyone would have such a carer, but that this restriction would provide a more homogeneous sample than would otherwise be the case.

The goal of image-based patient selection is to narrow the range of patient characteristics, leading to a more homogeneous sample, reducing within-group variance, and increasing the statistical power of the experimental design to demonstrate efficacy.

For example, a recent therapy study compared the clinical efficacy of singing and rhythmic speech in a relatively homogeneous sample of 15 patients with non-fluent aphasia and apraxia of speech (Stahl et al., 2013).

Usually, participants in an IPA study are expected to have certain experiences in common with one another: the small-scale nature of a basic IPA study shows how something is understood in a given context, and from a shared perspective, a method sometimes called homogeneous sampling.

Using these criteria (as well as that which stipulated that they should not be paid carers) we felt we would achieve a more homogeneous sample than if we had included people less closely involved, and one which would be confined to those with a significant input into the care of the dementia sufferer.
