The phrase "a minimal sample of" is correct and usable in written English.
It can be used when referring to a small or limited selection of items, data, or examples from a larger set.
Example: "In this study, we collected a minimal sample of responses to gauge initial reactions to the new product."
Alternatives: "a small subset of" or "a limited selection of".
The additional loss of some non-coding data from the plastid genome along with a few minor changes to intact reading frames within Cuscuta and Convolvulaceae have been reported and roughly mapped on a phylogeny of Cuscuta based on a minimal sampling of taxa [ 20].
With an estimated annual hospitalization rate (a primary outcome) of about 6.0%, allowing a maximal deviation of 1.2%, at an alpha error of 5%, a minimal sample size of 1204 subjects was required.
For the planned pair wise comparisons, to detect medium effects or larger (i.e., Cohen's d ≥ 0.5; [ 50]) with at least 80% power and a Bonferroni corrected alpha of 0.025, a minimal sample size of 64 in each group is needed.
Based on our experiences in past research, we presumed a drop-out rate of 10%, implying a minimal sample size of 21/.9 = 24 children in the care-as-usual condition and 36/.9 = 40 in each of the treatment conditions.
This is in agreement with Khatkar et al. [ 15] who suggested a minimal sample size of 400 and 75 for estimation of |D'| and r, respectively.
As a rule of thumb, and even in ideal sampling conditions, a minimal sample size of N = 50 is needed to obtain an acceptable estimate of the population parameter.
A power analysis revealed that if the correlation between male length and offspring viability were at the upper limit of our calculated confidence interval, a minimal sample size of 88 males and more than 21,300 experimentally fertilized eggs would be necessary to demonstrate the effect at alpha ≤ 0.05 with our experimental methods and with a statistical power of at least 80%.
21, 27 Assuming an alpha level of 0.05 with 80% power to detect 7% LOS points difference in endpoint excursion and 8% of 100 points in directional control with an anticipated dropout rate of 30% for the 48-week intervention, a minimal sample size of 70 participants for the TJQMBB was planned.
A minimal sample size of 444 and 55 animals is required for an accurate estimation of LD by |D'| and r, respectively.
Similar to factor analysis, where a minimal sample size of 10 is required per item by convention, a minimum sample size of 250 is generally requested for analyses such as those conducted here [ 25].
