Reliable


Definition:

  • (a.) Suitable or fit to be relied on; worthy of dependance or reliance; trustworthy.

Example Sentences:

  • (15) The quantitative method used for determination of HBDH is reliable, accurate, simple and rapid and therefore has better value in a clinical setting than electrophoresis and adsorption techniques which are laborious and time consuming.
  • (16) The capacity of granule-cell networks to separate overlapping patterns of activity on their inputs is adequate, with spatial variability in the secretion at synapses, but is improved if there is also temporal variability in the stochastic secretion at individual synapses, although this is at the expense of reliability in the network.
  • (17) Interexaminer reliability studies indicate that a standard method of motion palpation is quite feasible and accurate.
  • (18) In conclusion, 99Tcm-MIBI SPECT provides a reliable method for detecting CAD.
  • (19) As a result of measures taken to reduce artifacts and to improve the signal-to-noise ratio, the measurements were performed reliably, with little inconvenience for the patients; all measurements could be used for analysis.
  • (20) This method can characterize reliably flavivirus field isolates at the molecular level without extensive virus propagation and molecular cloning, and will be a valuable tool for molecular epidemiological studies.

Valid


Definition:

  • (a.) Strong; powerful; efficient.
  • (a.) Having sufficient strength or force; founded in truth; capable of being justified, defended, or supported; not weak or defective; sound; good; efficacious; as, a valid argument; a valid objection.
  • (a.) Having legal strength or force; executed with the proper formalities; incapable of being rightfully overthrown or set aside; as, a valid deed; a valid covenant; a valid instrument of any kind; a valid claim or title; a valid marriage.

Example Sentences:

  • (1) Unfortunately, due to confidentiality clauses that have been imposed on us by the Department of Immigration and Border Protection, we are unable to provide our full names and … titles … However, we believe the evidence that will be submitted will validate the statements that we are making in this submission.” The submission detailed specific allegations – including names and dates – of sexual abuse of child detainees, violence and bullying of children, suicide attempts by children and medical neglect.

  • (3) Single-case experimental designs are presented and discussed from several points of view: Historical antecedents, assessment of the dependent variable, internal and external validity and pre-experimental vs experimental single-case designs.
  • (4) An application is made to the validity of cancer risk items included in a cancer registry.
  • (5) Although measurements are easily obtained with a tape measure, the validity of these measurements is not known.
  • (6) This observation, reinforced by simultaneous determinations of cortisol levels in the internal spermatic and antecubital veins, practically excluded the validity of the theory of adrenal hormonal suppression of testicular tissues.
  • (7) However, each of the studies had numerous methodological flaws which biased their results against finding a relationship: either their outcome measures had questionable validity, their research designs were inappropriate, or the statistical analyses were poorly conceived.
  • (8) We found no statistically significant difference in one-year, biochemically validated, sustained cessation rates between the group offered the long-term follow-up visits (12.5%) and the group given the brief intervention (10.2%).
