### Questionare

A. Some people may not like math due to the fact that math is a building subject. Each year of education builds up top of each other. Since each year, the student learns a new building block, each year they will have another teacher or will have different experiences. If one year the teacher does not relate to a student or the student does not pay attention, the student will lose the build block and will struggle from then on unless the building block is later regained. This may be the reason why some students stuggle with math which leads to the dislike of math.

Q. Do you like or hate math? Why?

A. We like math beacause it is very straight forward. The answer is not ambigous, and there is a certain method to reach the answer. If the answer the student recieves is incorrect, there is always a reason why the answer is incorrect, and proof to back the correct answer. The proof is the method, and is not subjective.

Q. Do you think Math is important for "Artists"?

A. Math is not suitable for observational drawings. When drawing from observation, the artist uses the right hemisphere of the brain in order to percieve what is actually there rather than what the artists knows to be the symbol of the object. The symbol system derives from the left hemisphere of the brain as does math. However, some people make beautiful art from math, but it is not usually an observational drawing.

Q. How can math education improve?

A. We think that the math department should have a standard test that tests all areas of math ranging from kindergarden to the current grade. That way the teacher can assess the weakeness of the students and offer personal assistance for the weakenesses to regain the building blocks a sudent may not have in their education. TAKS should also be eliminated because it does not contribute to the joy of learning.

### Scatter plots, Statistics, and Hans

Here’s some Hans talking more about his dataset and global trends.

What are Scatter plots? Hmmm…

Scatter plots display dots representing a collection of data. These scatter plots determine if the data given is a positive or negative correlation or if it even has one at all. The purposes of these are to determine and examine the relationships between the variables. Each dot represents a single unit of data entered. The more dots entered the easier it is to see trends and patterns of the entered information.

Scatter plots are statistics applied to mathematics or the arts. Statistics are the representation of data.

Notes/Steps on scatter plots and graphing-

Push these buttons in order for scatter plot graphing/Section 2-5:

STAT (arrow) 1:EDIT - info – L1, L2 - Y= - PLOT1

Move arrow to highlight

Clear anything in Y=

ZOOM - 9:ZOOM - STAT – ENTER

Find equation

STAT (arrow) Cal - 4: Lin Reg (ax=b)

“Lin Reg (ax=b) L1(push: 2^{nd} +1), L2(2^{nd}+2), Y(Vars) (arrow) yVars – 1:Functon – ENTER

2^{nd}+ graph – Y= - 2^{nd} + Window – 2^{nd} + graph
