Washington served as a general and commander-in-chief of the colonial armies during the American Revolution, and later became the very first president of the United States, serving from 1789 to 1797.
Answer:A correlation
Explanation: This means there is a connection between two variables which can be either positive or negative.
Positive correlation occurs when two variables tends to increase at the same time, which means when one variable increases the other one also increases at the same time. Negative correlation occurs when one variable increases and the other one decreases all at the same time.
In this case having children at young age shows to have a connection with lower levels of education. Correlation though doesn't mean causation , which means it shows a connection but it doesn't mean the other variable causes the shift of the other variable.
