To describe the data represented in the scatterplot based on the x-axis (student's age) and the y-axis (number of times the student cried each month), the following vocabulary words can be used:
- Bivariate - The data involves two variables (age and number of times cried).
- Linear trend - If the data points suggest a linear relationship.
- Increasing - If the number of times cried generally increases as age increases (assuming that's what the plot indicates).
- Positive trend - If the data suggests that as age increases, the number of times cried also increases.
So, the applicable vocabulary words are:
- Bivariate
- Linear trend
- Positive trend
- Increasing
The terms "Univariate," "Proportional," and "Decreasing" would not be appropriate descriptors based on the provided context.
