<p>You’re confusing the concept of “mean” with majority. The mean of any set of data is not the majority (mode)- it is mathematical point that represents the ideal center value of the set (rather than the true center, the median).</p>
<p>For instance, the majority of all students at school Q (we’ll say 99 out of 100) could have an IQ of 100. However, one student might have an IQ of 100,000 (just an example of extremes here). Thus, the average IQ of students at School Q would be 1099, rather than the mode of 100. </p>
<p>This is all extremes, but I think it illustrates why you’re wrong, at least in your phrasings. You’re effectively taking the deconstructionist approach and saying selectivity is a meaningless construct perpetuated by the liberal east coast elite.</p>
<p>All the other people here are answering in the normal fashion, answering an inquiry into statistical patterns with, GASP!, the statistical data.</p>
<p>While it is certainly true that at various schools, or for various students with different talents and interests, it may be more of less difficult to gain admission to either school, selectivity, as defined by a statistical accounting of chance of admission represented by a ratio of # applied to # admitted, can be said directly to be in the favor of NU.</p>
<p>Does this have any bearing on a single data point however? No, not at all. I did not have a 27.5% chance of being admitted to Northwestern. I had a 100% chance of being admitted, or a 0% chance. For a single data point (student), who has only one iteration through the admissions cycle, you either will or will not be admitted, and it is NOT a game of chance- it is based on factors, and thus you will be admitted or not before your decision is made based on your application. </p>
<p>Sorry for what seems to be a tirade and perhaps condescending essay, but so few posters on CC seem to grasp the basics of statistics OR the implications those basics have (or don’t have) for their life.</p>
