<p>Which one is eligible for sat?</p>
<p>data, criteria ...etc Plural or not?</p>
<p>Don’t know which rules SAT is following but in the past the College Board/SAT has sometimes been wrong for what is singular or plural because of its failure to recognize accepted grammatical changes that have occurred over time, and, in that situation, you must also be wrong to answer the question correctly.</p>
<p>“Data” may have at one time been considered the plural of datum and thus plural but years of usage have established that data can replace datum as the singular and it is a singular mass noun even when referring to a lot of data. Thus, “the data is accurate” is now accepted over “the data are accurate.” </p>
<p>Criteria is still considered a plural that has not quite yet become a mass singular possibly because criteria has not replaced criterion yet as a singular and thus “the criteria are” is still correct.</p>
<p>Another is “none.” Though many believe none is always singular, it no longer is assuming that was ever the case (doubtful). It is plural when referring to a plural whole, such as “none of the tests are scheduled for today,” and singular when referring to part of a mass singular whole, such as “none of the pie is left.” The same distinction is made for “some” and “all.” However, “everyone” is considered a mass singular and thus singular, just as using the adjective “every” still leaves the noun that follows it singular.</p>
<p>The SAT does not test singular/plural for data, media, or none. Criteria and phenomena are still considered unambiguous, so the singular is criterion and phenomenon.</p>
