<p>“they claim only 10% of all their classes have over 100 students.”</p>
<p>I hate it when colleges and anybody fiddle with numbers like this.</p>
<p>that doesnt mean 10% of the classes you take will have over 100 students. lets look at it this way:</p>
<p>lets say you will take intro to physics with a class size of 180</p>
<p>next you can choose what physics class you want to take. you take quantum physics, a class with 20 students in.</p>
<p>but what happened to the other 160 students from intro to phys? they took other small classes, 8 other classes with 20 students in them.</p>
<p>So, thats 10 classes:
9 classes with 20 students in them
1 class with 180</p>
<p>10% of the classes have over 100 students, but 50% of the classes you take (in this scenario) have over 100 students in them.</p>
