The phrase "actual study sample" is correct and usable in written English.
It can be used when referring to the specific group of participants or subjects that were included in a research study.
Example: "The results of the experiment were based on the actual study sample, which consisted of 200 participants from various backgrounds."
Alternatives: "real study sample" or "true study sample".
We piloted questionnaires in each country with postgraduate doctors not included in the actual study sample.
However, when the LD structure of the reference population differs from the LD in the actual study sample, MGAS can be liberal or conservative: we refer to Li et al.
If they had been included in the present sample, and given their likely diagnoses, the diagnostic distribution would have been 11% anorexia nervosa, 31% bulimia nervosa and 58% eating disorder NOS, figures that differ little from those of the actual study sample.
For this reason, in an actual association study, sampling variation would be considered and could be estimated parametrically by including in the design sub-pools of independent samples of cases and controls.
In an actual association study, sampling variation is added to the parameters considered in the present study which focused on technical replicates within and between DNA pools of the same group of individuals and compared allele frequency estimates for pooled DNA from this group of individuals to individual genotyping.
A weakness of these studies is that none reported the actual scores of the study sample and hence the results were simply recorded as falling within either the introversion or extraversion dimension.
K-means nonhierarchical cluster analysis was then used to divide the study sample into actual clusters.

Secondly, diet cost used as an indicator of monetary value of the diet was based on retail food prices rather than actual expenditures made by the study sample.
Second, KGG v3.0 facilitates estimation of the genetic correlation matrix from a reference population like HapMap: actual genotypes of study samples do not need to be available.
Two other speakers presented smaller-scale Illumina DASL® technical studies, highlighting the risks still present from assay and sample variability, and the need for pilot studies using samples from the actual study population.
