You can also draw a "Line of Best Fit" (also called a "Trend Line") on your scatter plot:
Try to have the line as close as possible to all points, and as many points above the line as below.

  1. Ok the ice cream is a bit harder in math twerms but in logical terms of course. When it gets hotter lots of ppl get ice cream.
    But mathamtically there is an increase of about 110$ in sales for every 2.4 degrees C

  2. I also got a math brain buster
    In a world where 1+7=8 ,2+3=10, 5+4=45, what does 12+12=?

    Any one who figures it out without cheating is super good at math and logical thinking.

  3. This data makes sense because in real life people eat more ice cream if it is hotter outside becasue it cools them down, but in the winter, people don't want ice cream becasue it is cold outside and they would rather have soup or something warm.
