1. choose the best answer.

which type of relationship exists between these variables?
inverse relationship
direct relationship
no relationship

1. choose the best answer.

which statement is true based on the type of relationship these two variables have?
the more a student was absent, the lower the science grade.
the less a student was absent, the lower the science grade.
there is no relationship between the two variables.

Explanation:

• For question 12: In an inverse relationship, as one variable increases, the other decreases. Here, as the number of absences (one variable) increases, the science grade (another variable) decreases. In a direct relationship, both variables change in the same direction. Since the data points follow a trend where an increase in one leads to a decrease in the other, it's not a direct or no - relationship.
• For question 13: Based on the inverse relationship (from question 12), when the number of absences (a variable) is more (increase), the science grade (the other variable) is lower (decrease). The second option is the opposite of what the inverse relationship shows. And we have already established there is a relationship (inverse), so the third option is wrong.

Answer:

1. Inverse relationship
2. The more a student was absent, the lower the science grade.
