<p>Does anyone know what that standard deviation problem's answer was?</p>

<p>What were people's thoughts on the difficulty of the test? I thought it was not that hard, except for a select number of problems</p>

<p>what does standard deviation mean?</p>

<p>Does this</a> topic not suffice for you?</p>

<p>General Pak: I think they took it on Sunday instead of Saturday so different form.</p>

<p>scroll down and look at the graph.. the center is mean. -1 SD to 1 SD represents 68% of the data. </p>

<p>SAT1 for example uses standard deviations to curve scores for each section. they want around 500 to be the national mean(50%), 600(82%), 700(95%), 800(99.%)</p>

<p>did you choose the graph that was totally concentrated at the score of 80? (that was the only score...)
what did you guys think?
any more problems u remember?</p>

<p>Yeah, i found out that the graph with only one bar, A, was the correct one. I thought the test was pretty easy, I don't think there were more than 3 hard ones....</p>

<p>agreed... i ran out of time of the last 4 even though i know i could have done them but there were really only 3 harder ones before that- any others to discuss?</p>

<p>oh the question with the person and the flagpole or kite or something of the sort and they told you an angle and asked for the height of the flagpole/kite (sry all the tests are getting jumbled in my mind), did you place the angle in the interior I<em>here\ (I</em>) or like make the other triangle? i couldnt remember which to do... if you want just PM me and give me ure s/n and we can discuss...</p>
