Question

The x-axis represents a students age in years and the y-axis represents the number of times the student cried each month on average.

What type of data is represented in this scatterplot?


A scatter plot is displayed. The x and y axes are labeled, with tick marks indicating units. Approximately 20 small, reddish-brown circles are scattered across the graph. The points are dispersed, with no clear clustering or strong correlation visible; they do not appear to closely follow any particular pattern or trend line.

Answer 1

The data represented in the scatterplot can be described as follows:

- The x-axis (student's age in years) and the y-axis (number of times the student cried each month on average) are both numerical, specifically they are continuous variables because they can take on any value within a range.
- The relationship between the two variables is bivariate, meaning that it involves two different variables (age and crying frequency).

So the appropriate responses based on the type of data represented in the scatterplot are:

1. **numerical**
2. **continuous**
3. **bivariate**

If only two responses are allowed, "numerical" and "bivariate" would be the most inclusive terms, while if three responses are accepted, you can include "continuous" as well.
