How to find the mean is by the sum(adding) of a set of values divided by the number of values in the set.
eg. 1+2+3=6/3 eg. 4,5,8,9,9
3 sets of values
=4+5+8+9+9/5
=35/5
=7<- this is the mean. a.k.a average
Try this mean, median, mode
A) 7,8,6,9,9,5,7,7,8,4
mean-7
median-7
mode-7
B) 300,250,300,300,400 pg.431-433 #2-16

-Here is a video about mean, median and mode. I hope it helps:)
Nobody,s commenting on the blog anymore. I guess everyone thinks it ok to fail just because we don't have math anymore. I hope someone looks at my video it pretty funny. But I don't think anyone will because there so busy studieng or just happy that exams are almost over that you don't have to go on the blog. So you just sit home and relax. It's not cool or fun, I know I know I do it to but this year I learned somethings and I have some goals to. Mr.Issy is right. Why woudnt you want a couple of marks just to write a few lines. I also learned this year to not give up no matter what because we all don't know what will happen in the future and I learned to be confident. When we had track and field I was not confident but I relised that when your confident its the key and you do better in life cause no one is perfect. I also learned that you have friends that care about you but I never noticed that. I was all like I don't have any friends but never mind that I wasn't looking. I have really good friends like Lizelle, Suzie,Krstal and a lot of people that I never noticed that were actually trieng to help me not make fun of me but I just pushed them away without knowing. I hope you guys forgive me. I learned so many things this year that I can't finish. All the things I learned to do and not do this year will help me a lot next year.People still make fun of me and other people who are like me and don't fit in. I totally experienced it and know I know how other people feel out there. If your mean and your reading this stop what youve been doing because when your hurting someone your hurting yourself to because were all a familly so obviously you'll feel bad. If you think I'm weird to love all my friends and every single one of you think again. I learned that words do hurt inside but for me I will only give the opposite of what the bully wants from now on, sourness not the suger anymore. Next year I wont let anything like that get through me because I have my shield, CONFIDENCE. I don't care if it's wierd that I stand out because I'm big and don't wear whats in style I'm me and I won't let anybody change that. Stop making fun of Mussie why do you waste all that time making fun of people when you could finish your work so you don't have homework. You know being a bully is kinda being a crinimal. Well I should stop talking about crimes. Ok were was I.MMMMMMM Ok so I'm done.

TRUE FRIEND:)
ReplyDeleteI'm back to tell you more stuff. Throughout the year big things were happining. Like at the beginning of the year I was lonely and queit right. But then came along Sandra she was and is my tuly best friend. She was one of them that actually helped me all along and she was the only one that kept on saying that I am the most prettiest girl ever. I didn't believe her. You know how friends are they dont want you to feel bad about anything thats one of the reasons why they are our friends. But then I started to relise that everything good Sandra was saying about me was true then I beleived her. She is a person you can look up to whether it's homework,studieng or secrets shes always there for me when I need help. Shes easy to talk to. At the begining of the year I thought Sandra was some popualer meanie I was wrong. I just have to say all those friends who were looking out for me including Sandra you guys are special friends more than the earth's gold.
-Sophia:)
P.S I'll miss you Sandy

Wow Sophia! I am so touched about what you said about me in your comment. Everything you said in all your comments were true, especially the first one, I sure hope people read them:) Your post was very good, and im happy you made a blog it was very understandable, colourful and I liked how you put a video link (although the video is pretty wierd, although it still talks about measures of central tendancy). Well overall, good job:D

ReplyDeleteGood job Sophia. I liked the colours you used, purple & blue.(: The video was kind of weird but I got a laugh out of it.(: It talked about mean, median, mode but I got distracted by the colourful costumes and such, anyways it was okay.
ReplyDeleteYour comments, wow they're so long.O: But they were wow, sorry if I've been mean to you or if it seems like I've ignored you, it's just sometimes I'm trying to do my work, or you're being kind of distracting. Overall, good blog. (:
