Answer:
The correct answer is:
There is a positive correlation because women's weight tend to increase when height increases (D)
Step-by-step explanation:
The units that might be used to measure each variable are:
Height : meter (m) or foot (plural, feet) (Ft.)
weight : kilograms (kg) or Pounds (lb)
A positive correlation is said to occur between two variables when they both move in the same direction, that is, when they both increase or decrease, while a negative correlation occurs when the movement is not in tandem, i.e, as one increases, the other decreases. The relationship between height and weight is a positive correlation because, an increase in height, which is mainly as a result of elongation of bones, leads to an accumulated increase in total body mass, which in turn increases the body weight.
