The average SAT I composite score on CC

Test Preparation

<p>This will be fairly interesting. </p>

<p>Here's what to do:
current average + (your score - current average) / number of scores</p>

<p>That is, if you got a 1100 and the average of 10 scores is 1400, you'd do: 1400 + (1100 - 1400)/10 = 1400 + (-300)/10 = 1400 - 30 = 1370. Congrats, you've just brought the average down 30 points to a 1370.</p>

<p>Model your post on the post below:
COUNT: 1 (take count from previous post)
Score: 1410
0 + (1410 - 0)/1 = 1410
NEW AVERAGE: 1410
New COUNT: 2</p>

2

<p>This looks complicated, but might be fun....
Score: 1110
1410+(1110-1410)/2=555
NEW AVERAGE: 555</p>

3

<p>There's got to be something wrong with that.</p>

4

<p>I don't think this is right <strong>hp</strong>....</p>

<p>Can't you just do a normal average?
(1410 + 1110)/2=1260</p>

5

<p>schwaby, that doesn't work either. Try my way.</p>

6

<p>to get an avg, all you have to do is: 1) add all the scores together and divide by how many there are.</p>

7

<p>He's right... you're supposed to do 1410 - (300/2) = 1260.</p>

<p>Anyways...</p>

<p>1260 + (1430 - 1260)/3 = 1260 + 170/3 = 1317</p>

8

<p>I wonder how hp got a 1410, lol.</p>

9

<p>Yeah. Looks like you had an order of operations mistake there Rbase. You divided (1410-300) by 2, instead of just the 300 by 2.</p>

10

<p>omg, here is how u calculate average
(average<em>number of people+your score)/number of people plus u=new average
for example
(1410</em>1+1110)/(1+1)=1260
and now
if a 1400 comes (me)
(1260*2)/(2+1)=1307
etc...</p>

11

<p>EPorrell, that's over complicated and wrong. You don't need to add and subtract all those numbers.</p>

<p>1430-1260 + 1260= 1430. Do it my way.</p>

12

<p>I repeat: to get an avg, all you have to do is: 1) add all the scores together and divide by how many there are.</p>

<p>HP's 1410+
My 1110+
E Porrell's 1430+
Newbyreborn's 1400=5350</p>

<p>Divide 5350 by 4, because there are 4 scores. That gives you 1337.5 or 1338 avg composite score. That is ALL you have to do.</p>

13

<p>I honestly can't believe that I scored under 1200 and am the lowest CC SAT scorer (520 on math), and I have to teach you guys how to calculate an average...</p>

14

<p>I know how to calculate an avg. I was just illustrating the reason you calculated an incorrect average. (Order of Operations, I believe it's called).</p>

15

<p>Rbase
(average*number of people+your score)/(number of people plus u)=new average</p>

<p>is the EXACT same thing your saying. prevaverage * number of people + your score is the same as summiing up everyones score, but you don't have to look at everyones score you just have to know how many people have posted so you can properly weight it. Your method instead of taking the average and multiplying by the number of people you're adding up all the inidividual scores. The result is the same, you're arguing over the exact same formula.</p>

16

<p>oh alright.. my bad guys</p>

17

<p>The average on ******* is about a 1427, I think. That's not too shabby. My 1460 will bring that up.</p>

18

<p>this is quite possibly the most hilarious thread I have ever seen... a bunch of intelligent students arguing over how to find an average. My score is a 1370 (or 1470 if I am allowed to convert my ACT), so the new average (including Mekrob's 1460) is 1363.</p>

19

<p>How about everyone post their scores, and after like 100 or so posts, you calculate the average?</p>

20

<p>old sat average cc score</p>

<p>1363 + (1510 - 1363)/7 = 1384
hehe my 1510 brought up the average 21 points</p>

<p>you know this thread only works until march, then you have to do the average with writing
include writing sat 2... new sat average cc score</p>

<p>0 + (2290 - 0)/1 = 2290</p>

<p>yea i got an 800 math... i get this... lol...</p>
