Here's an explanation and example. <br /> <br /> Standard deviation is a statistical measure of spread or variability. The standard deviation is tells you how closely the data are clustered around the average. We want to use the aperture and background subtraction settings that give us the smallest standard deviation for a star that is not varying.

The standard deviation is tells you how closely the data are clustered around the average.

The standard deviation is tells you how closely the data are clustered around the average. We want to use the aperture and background subtraction settings that give us the smallest standard deviation for a star that is not varying. Our varying stars will of course have large standard deviations because they ARE varying.<br /> <br /> Formula: [[image:stddev.jpg]]<br /> <br /> Standard Deviation<br /> standard deviation formula <br /> <br /> where Σ = Sum of<br /> X = Individual score<br /> M = Mean (average) of all scores<br /> N = Sample size (Number of scores)<br /> <br /> <br /> '''Example: Find the Standard deviation of 3,2,1,1,and 3'''<br /> <br /> Step 1: Calculate the mean (average) and deviation.<br /> {| border=&quot;1&quot;<br /> |-<br /> |'''X'''<br /> |'''M'''<br /> |'''(X-M)''' <br /> |'''(X-M)2'''<br /> |-<br /> |3 <br /> |2<br /> |1<br /> |1<br /> |-<br /> |2<br /> |2<br /> |0<br /> |0<br /> |-<br /> |1<br /> |2<br /> |(-1)<br /> |1<br /> |-<br /> |-<br /> |1<br /> |2<br /> |(-1)<br /> |1<br /> |-<br /> |3<br /> |2<br /> |1<br /> |1<br /> |-<br /> |}<br /> <br /> <br /> <br /> Step 2:Find the sum of (X-M)2<br /> 1+0+1+1+1 = 4 <br /> <br /> Step 3:N = 5, the total number of values.Find N-1.<br /> 5-1 = 4<br /> <br /> Step 4:Now find Standard Deviation using the formula.<br /> √4/√4 = 1<br /> <br /> = '''Individual School Pages''' =<br /> == '''Communicating on Wiki!!!''' ==<br /> Wiki will tell you when anyone makes an edit or comment to any page if you&lt;BR&gt;<br /> &lt;BR&gt;-log in, click on my preferences, put your whole name in for your signature if you want, check off all of the boxes at the bottom to turn on the email function<br /> &lt;BR&gt;-go to the pages you want to &quot;watch&quot; and click on on the Watch tab, you'll get an email if there is a change to these pages <br /> &lt;BR&gt;-watch your practice page and everyone elses practice pages for now so you know any of us make a comment or put up something new<br /> &lt;BR&gt;-'''Please''' make comments using the discussion tab on anything and everything right now! <br /> &lt;BR&gt;-if you feel the urge to make the comment on the actual page, that's ok for any pages under Variability of the Mid IR Sky seeing that these are our pages, but if you comment on the main coolwiki, use the discussion page.<br /> <br /> <br /> ==='''[[Here's some examples of how to edit a wiki page]]'''===<br /> &lt;BR&gt;&lt;BR&gt;<br /> <br /> == [[Lincoln-Way North High School in Frankfort, Illinois]] ==<br /> [[Image:Phoenix.jpg]][[Image:LWN.jpg]][[Image:Phoenix.jpg]]&lt;BR&gt;<br /> '''Teacher - Peggy Piper - Students - Joey R. - Rebecca R. - Justin C.''' &lt;BR&gt;&lt;BR&gt;<br /> Here are our light curves with standard deviations for the three test stars using Source Model B. &lt;BR&gt; From top to bottom in each graph, they are stars #1, #2, and #3. &lt;BR&gt;&lt;BR&gt;<br /> <br /> '''Mrs. P Question to you - which aperture background should we choose?

I hope I am not causing confusion. It is 11:15 am CST on Friday Jan. 22, 2010. I am trying to see what this does, since I have &quot;editing&quot; status here. Is this something we use instead of email, or is it a place to create documents that we edit together?<br /> Rich<br /> ps-Should something like this be in the &quot;discussion&quot; tab rather than the &quot;article&quot; tab?<br /> <br /> Hi Rich - no, you're not causing confusion, you're doing it exactly right! These pages under &quot;current research activities&quot; are really sort of &quot;shared white boards&quot;. The other half of the wiki (under &quot;research tools&quot;) are more articles, and in those cases, yes, questions should go into the discussion pages. I copied some headers in here, but please see some of the &quot;current research activity&quot; pages for the other current teams to see how they are using their pages. (e.g., [[CG4_Current_Research_Activities| cg4's page]]) Oh, and you can use this for whatever you want -- proposal preparation, conversation, sharing plots, brainstorming, etc. --[[User:Rebull|Rebull]] 13:12, 22 January 2010 (PST)</div> Rosignolo
