Q. Based on the given mixed graph, which of the following statements can be inferred about the relationship between education level and income?
A.
Higher education always leads to higher income.
B.
There is a positive correlation between education level and income.
C.
Income is solely determined by education level.
D.
Education level has no impact on income.
Solution
The graph indicates a positive correlation, suggesting that as education level increases, income tends to increase as well, but it does not imply causation.
Correct Answer:
B
— There is a positive correlation between education level and income.
Q. Based on the mixed graph provided, which of the following statements can be inferred about the relationship between variable A and variable B? (2023)

Q. Based on the mixed graph provided, which of the following statements can be inferred about the relationship between education level and income?
A.
Higher education levels lead to higher income.
B.
Income has no correlation with education level.
C.
Lower education levels result in higher income.
D.
Education level is irrelevant to income.
Solution
The graph indicates a positive correlation between education level and income, suggesting that higher education levels generally lead to higher income.
Correct Answer:
A
— Higher education levels lead to higher income.
Q. Based on the mixed graph provided, which of the following statements can be inferred about the relationship between the two variables depicted? (2023)
A.
There is a direct correlation between the two variables.
B.
The variables are independent of each other.
C.
One variable causes changes in the other.
D.
The relationship is non-linear.
Solution
The graph shows a clear upward trend, indicating a direct correlation between the two variables.
Correct Answer:
A
— There is a direct correlation between the two variables.
Q. From the mixed graph, which conclusion can be drawn about the relationship between technology adoption and productivity?
A.
Higher technology adoption leads to lower productivity.
B.
There is no relationship between technology adoption and productivity.
C.
Increased technology adoption correlates with higher productivity.
D.
Productivity is solely dependent on workforce size.
Solution
The graph indicates a positive correlation between technology adoption and productivity, suggesting that higher adoption rates lead to increased productivity.
Correct Answer:
C
— Increased technology adoption correlates with higher productivity.
