Question

Scatterplots - Statistics

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).

Answer 1

What is the label for the horizontal axis?

What is the label for the vertical axis?

Well, the horizontal axis is the same thing as the x-axis, and the vertical axis is the same thing as the y-axis. The points are labeled (x, y). It states that the x and y values are ordered in meters/seconds. That means the x-axis will be meters, and the y-axis will be seconds.

Therefore, the label for the horizontal axis is meters, and the label for the vertical axis is seconds.

Answer 2

Here's the scatter plot:

Answer 3

The meter measurements are very close to each other. However, (4, 0.76) is an outlier, because it's y-value is a lot smaller than the others.

Answer 4

@iGreen I found it difficult to comment on shape, outliers, ect with only 5 points to look at.

Answer 5

Yes, it is kind of difficult.

Answer 6

@iGreen What would you say the shape or form is?

Answer 7

Left-skewed? @iGreen

Answer 8

Yeah..that sounds about right. It's very scattered so it's kind of hard to tell.

Answer 9

Okay, and any comments on strength? @iGreen
