Standard Deviation

In class today we corrected lesson 2 standard deviation numbers 1 - 6. When finding the square root the number will always be positive. To find the range you must subtract the biggest number and the smallest number. To find the mean you must add all the numbers and then divede them by how many numbers there are Ex: 57+58+59+60/4 = 58.5 = th mean.

Pilot Test..

Mr. Max talked bout a pre exam called the Pilot Test... He asked us all if we were interested in writing it, it is a 90 min test and we have from between December 11 and January 18 to decide on doing the test. What's your decision on this?? Hang a comment on the post and let Max know.

At the beginning of class Mr. Max made a "plan" for the class because he didnt have his computer and smart board hooked up.... We talked about MOGA madness that is happening on Wed afternoon. He encourages us to buy a bag of grain to support our school, so get out there and buy some grain make the Big Guy happy...
This Friday is parent teacher and us students are welcome to attend with our parents. The Big Guy isnt going to say anything mean or humiliating (unless you really deserve it!!) he is just going to let your parents know how your progress in his class is going.
Mr. Max is checking our homework assignment from Friday. They were the statistics questions lesson 1 and 2.
So remember all y'all buy some grain support the case...

Lesson 2: Measures Of Variability

How to Determine Mean: example: 42+53+59+66+68+68+71+76+83+94 You then take those numbers add them all up and divide by how many there are so in this case there are 10 so divide it by 10 and which is 68.

Statistics...

Today in math we started a new chapter.... "Statistics"...
