<p>Let me guess. You just finished a statistics class and now you think you’re some kind of whiz kid? Oh god…</p>
<p>Assuming your data is accurate, you claim</p>
<p>
You then say
68% of the average GPA? What does that mean? You are incorrectly using the word average. Did you mean to say that 68% of the admits to L&S had a GPA below 3.68???</p>
<p>Because that’s false. You should have paid better attention in class.</p>
<p>If the average GPA is 3.51 and the std is .169, then the GPA of students who are +1 standard deviation away from the mean is 3.679. Assuming a standard normal approximation, this means that .84134 (or 84.134%) of the data is contained up to that point. **That means that 84.134% of the students had a GPA of 3.68 or lower. **The 68% BS you “calculated” comes from poor application of empirical rule. </p>
<p>Empirical rule approximates that in a normal distribution, 68% of the data lies between one standard deviation. That would be the mean plus or minus one std. Therefore, that means that 68% of admitted students had a GPA between 3.51 - .169 and 3.51 + 1.69. Or in other words, 68% were between 3.341 and 3.679.</p>
<p>The fact that you “calculated” this totally wrong makes me very skeptical about your data and your other “calculations.” Instead of trying to act smart on teh interwebs, you should go re-read your book or maybe retake your class.</p>
<p>Honestly people, stop wasting your time trying to guesstimate your chances and focus on your studies. Want to increase your “chance” of getting in? Go study, volunteer, join a club, etc.</p>
<p>I remember how stressful this period can be, but try not waste too much time on BS like this. Best of luck to you all.</p>
