4.1 and Follow Up

If you know a persons arm span can you figure out his height? No, I don't think so because some people have really long arms and some people think that the height has to be bigger then the arms but it doesn't because some people have really long arms example the student on (145,140) has longer arm span then his or her height.

Gather your math classes data and then make a scatter plot and the figure out the answer to the question above?

Follow Up

1. What is the number of class mates in your math class that are on the line? What is the truth about arm span compared to height for the points on this line? None of my math class mates are on the line in this scatter plot. If there was a student on the line he would be perfect because he has the same arm span and height.

2. What is the truth about arm span compared to height under the diagonal line? Points below show that the student who are below the line most probably have short arms and he/she is tall example the point on (142,143) this student has long arms but short height.

3. What is the truth about arm span compared to height above the diagonal line? The truth is people who are above the diagonal line most probably have long arms and short height example the point on (157,161) this student has long arms but short height then his arm span.
