The negative trend in this scatterplot indicates that the two variables, weight and desired weight change, are negatively correlated. That means as a student's weight goes up, his or her desired weight change goes down (meaning that it is a negative number). If you draw a line of best fit through the data (meaning a straight line that approximately goes through the center of the data), students who weight 100 pounds will want to gain...
The negative trend in this scatterplot indicates that the two variables, weight and desired weight change, are negatively correlated. That means as a student's weight goes up, his or her desired weight change goes down (meaning that it is a negative number). If you draw a line of best fit through the data (meaning a straight line that approximately goes through the center of the data), students who weight 100 pounds will want to gain about 10 pounds (positive ten), while students who weigh about 130 will not want to lose any weight (meaning a value of 0). As students' weights increase, their desired weights become negative because they want to lose weight. For example, a student who weighs 180 pounds will have a desired weight change of approximately negative 40. Therefore, as a student's weight increases, the desired weight change becomes increasingly negative, meaning that the variables are negatively correlated and there is a negative trend in the data.
