Determining Relationships Using Student Homework Data
Problem Statement:

A high school math teacher decides to divide her class in to two groups and record a score for each student’s satisfaction based on the number of homework assignments assigned. She assigns students who claim to enjoy math to Group 1, and students who claim to dislike math to Group 2. The data collected from this experiment is plotted on the coordinate grid. Run the program, and for each group determine the relationship between the number of homework assignments and student satisfaction scores.

```/* Code generated by RoboBlockly v2.0 */
double variable;

printf("What is the relationship between number of homework assignments and student satisfaction score for Group 1? (positive correlation, negative correlation, or no correlation?)"+"\n");
scanf("%lf", &variable);
printf("What is the relationship between number of homework assignments and student satisfaction score for Group 2? (positive correlation, negative correlation, or no correlation?)"+"\n");
scanf("%lf", &variable);
printf("What is the relationship between number of homework assignments and student satisfaction for the entire class (both groups together)? (positive correlation, negative correlation, or no correlation?)"+"\n");
scanf("%lf", &variable);
```
