The data below were gathered on a random sample of 5 basking sharks, swimming through the water and filter-feeding, i.e. letting the water bring food into their mouths.

Body Length (meters) Column 1

Mean Speed (meters/seconds) Column 2

4 0.89
4.5 0.83
4 0.76
6.5 0.94
5.5 0.94

Construct a scatterplot of the data and answer the following questions:
(a) What is the label for the horizontal axis?
(b) What is the label for the vertical axis?
(c) Interpret the scatterplot (comment on association, form, strength, and outliers).

Given:
Body length (meters) Mean Speed (meters/seconds) 4                                            0.89 
4.5                                         0.83 4                                            0.76 6.5                                         0.94 5.5                                         0.94 

The horizontal axis is the x-axis. The values reflected in this axis is the body length of the shark.

The vertical axis is the y-axis. The values reflected in this axis is the mean speed.

Graph your own scatter plot.
point 1 (4, 0.89)
point 2 (4.5, 0.83)
point 3 (4, 0.76)
point 4 ( 6.5, 0.94)
point 5 (5.5, 0.94)

The correct answers are:

Body length; Mean Speed; There appear to be no outliers, the graph seems to have a strong positive association and appears to be nearly linear in form.  The graph is attached.

Explanation:

Since body length is in column 1, that will be the label of the horizontal axis.  The mean speed is in column 2, so that will be the label of the vertical axis.  

The points are very tightly grouped and appear to be slightly increasing.  There are no points that are very different than the rest, so there are no outliers.
