A Scientific Thanksgiving

I have to do a science project for my secondary science methods class so I had to recruit all of my family to be my little guinea pigs. All they had to do is 3 things...

Dip your hand in water...

Measure the circumference of your hand...

Measure the length of your hand...

Here is the data.

Length had a linear R^2 value of 0.852. Not very good (that is what I wanted so I guess it is bad but good).

Circumference hand an R^2 value of 0.917. Getting better but still not a great value (I wanted this as well).

Multiplying the 2 values together had an R^2 value of 0.935. It is the best. This is what I wanted.



What I did was investigation of volume. Why does it have to be 3-D? Now I need to go and print everything out and put it all purtified onto my 3-fold board. Funny thing is that people in my class thought that I did a "hard" project. He he!!

I don't even know how to read your value. I wouldn't even know where to start. Great pictures, where did you get them?

Good grief Mom!!! I took one of them and you took the other two. Thanks for doing it for me.
