My Mathcasts

You make a mathcast by going on Screenr and pressing the record button. Next, you pull up paint on your computer and have your tablet ready. you move the screen on screenr to fit into the paint window. you write out your problem on paint with your tablet and solve. when you are done, you press publish and done and then write a description of the mathcast with a hashtag for twitter.
your mathcast is posted on twitter and you are done!

I liked mathcasts because you really had to understand the math concept you were assigned in order to make one. They were useful because I had to make sure i fully understood the concept and problem. I think that they were fun to make, but i hated listening to the sound of my own voice!
I definitely think that we should keep making mathcasts in math!

Merritts scattered data forms

First i created a form and asked:
Name
How many pets do you have?
What is your favorite\lucky number?
I chose the first question because it was interesting and it would be good to graph on the x axis. I chose the question what is your lucky number because it was unique from what everyone elses question and it would be interesting to see the average lucky number and the lucky numbers all mapped out.

Then after i collected responses, I made a chart of my data. Here is the scatter plot:

Here is my scatter plot graph with the line of best fit:

Here is my work on finding the slope of my line of fit:

I used the two equations y1-y2 over x1-x2 to get my slope of 19. Then i used the equation y=mx+b to get the equation 13=19-6

Then i entered my data on the graphing calculator.

The correlation between my two questions was positive but very close to zero.  There wasn't much correlation though because the amount of pets you have usually does not depend on your lucky number. 

A type of question that could be answered on my line of best fit is if your lucky number was higher, would it have an impact on the amount of pets you had, or vise-versa.
