Hair Lenght vs. Height

In the graph of Hair length vs. height I can see that the graph has many scattered points in the graph. The information that the graph is giving us is that not all of our class mates that have a high height ten to have a long length of hair. I believe that there is no correlation between these two variables because neither height or hair length is affecting one another to show how they are related. If the graph where to be set up differently like by gender it would be more helpful to interpret the data that was given. I we where to take out some extreme data point then there might be a correlation between these two variables.

Reading Scatter plots and Understanding Correlations

In the graph there is our shoe sizes vs our heights.There is a relationship between the shoe's height and size. In the graph there seems to be not much of a correlation because the higher in the shoe size the height of our classmates is a negative position. But there are just a few positions that the higher the shoe size the higher the height of our classmates are. I Believe that neither the the shoe causes the height to change; and the height causes the shoe size to change.
