Question

use the following scatterplot to answer questions 7, 8, and 9. kylie gathered data for her science fair project and created the following scatterplot. 7. what is the independent variable? a. kylie b. science fair project c. amount of rainfall d. day of the month 8. what is the dependent variable? a. kylie b. science fair project c. amount of rainfall d. day of the month 9. which of the following describes the relationship? a. weak positive correlation b. weak negative correlation c. strong positive correlation d. strong negative correlation e. no correlation

Explanation:

Step1: Recall independent - variable definition

The independent variable is the variable that is manipulated or changed in an experiment or data - collection. In a scatter - plot, it is usually plotted on the x - axis. Here, the x - axis is labeled "Day of the month".

Step2: Recall dependent - variable definition

The dependent variable is the variable that is being measured and depends on the independent variable. In a scatter - plot, it is usually plotted on the y - axis. Here, the y - axis is labeled "Amount of rainfall".

Step3: Analyze the correlation

As the day of the month increases, the amount of rainfall generally decreases. The points in the scatter - plot follow a downward trend, indicating a negative correlation. Also, the points are relatively close to a straight - line pattern, suggesting a strong correlation.

Answer:

1. d. Day of the month
2. c. Amount of rainfall
3. d. Strong Negative correlation
