Another post, yay~ OuO; And yet again, we are learning about standard deviation, except this time it has a TWIST. For example, I looked online (in the achive statistics for Edmodo) and copied down crime statistics, just for a little practice. I have listed below exactly what it was that I investigated~
Standard deviation σ - Crime statistics for Alaska, USA from 1990-2000. -Burglary-
5,582 (- 5164.5) = 417.5
5,170 (- 5164.5) = 5.5
4,893 (- 5164.5) = 271.5
4,848 (- 5164.5) = 316.5
5,055 (- 5164.5) = 109.5
5,118 (- 5164.5) = 46.5
4,276 (- 5164.5) = 888.5
4,098 (- 5164.5) = 1066.5
3,787 (- 5164.5) = 1377.5
3,899 (- 5164.5) = 1265.5
+___________________
=5765/10 =
√576.5 = σ
Here is most of the data I searched and sumed up. I actually like Standard Deviation now. Its like, not easy, but not hard ♥~
Besides this, another thing I haven't quite grasped yet, but I do enjoy is the Mean Absolute Deviation. Its still kind of hard to understand, but, eh. I like it =u=;
Anywho, theres my reflection for today~ I hope thats enough o3o
Peace, Love, and Happiness forever,

Reflection? I guess...
So! Here I am, posting up on Blogger.com all about Algebra and how tiring awesome it is <3 I've never actually had a blog before but so far its real easy to use and I like it very much. I also like the fact that I can make my own custom backgrounds with some of my digital art projects
Ok. So, as I gather, Reflection is supposed to be based on what you learned throughout the week. I'll do that instead of pointlessly babbling <3
This week, I was absent a lot. But, I would like people to know I have still managed to get a firm hold on some of the current lesson. Standard Deviation, is what its called. Now, this bad boy is very difficult to solve unless one knows the proper steps. Thanks to my Algebra class, I am surviving and understanding! Two birds with one stone, OH YEAH!~ <3 FFFFFFF. I love this text size thing. Mostly because its REALLY hard to read. Even for me! 8U Anywho, thats about all... I guess. I still don't understand this, but eh, I'll manage.
Peace 4ever,
Kari
