<p>This isn't a homework question.</p>
<p>In a class of 12 kids (my AP Lit class) - how can the median be a 95% for a certain essay, but the class avg. is a 70%? Doesn't that seem off? How do you numbers????</p>
<p>dunno maybe u class is chunk : 100, 100, 100, 100, 98, 95, 95, 65, 40, 30, 15, 10</p>
<p>Lots of high scores and then some insanely low ones.</p>
<p>^ yeah 95 is just the middle grade. It really isn’t that good for plotting data. Think of mode as well–the mode for sluchy523’s 12 grades is 100, but the average is 70. That’s even more far off compared to 95.</p>
<p>It was the kind of assignment where you either got like an 80+ or a 0, since it was pretty much effort based.</p>
<p>The mean is pulled toward the skew, but the median is resistant to outliers. That pretty much means most students in your class got at or near a 95, but one or two zeros brings the average down a lot. </p>
<p>The same thing would happen if most of your class failed and got a score near 50, but one or two people got high A’s - the median would stay close to what most students got, but the mean would be pulled up a lot. </p>
<p>This question just helped me study for AP Stats, yay! We have a quiz over this next class lmao.</p>
<p>I’m glad I could help, lol. :)</p>
