Answer:
Shape (From)- A scattered plot shows the relationship between two quantitative variables measured for the same individuals. The values of one variable appear on the horizontal axis, and the values of the other variable appear on the vertical axis. Each individual in the data appears as a point on the graph.
Trend (Direction)- Scatter Plots show a positive trend if y tends to increase as x increases or if y tends to decrease as the x decreases. Scatter Plots show a negative trend if one value tends to increase and the other tends to decrease. A scatter plot shows no trend (correlation) if there is no obvious pattern.
Variation (Strength)- For a heteroscedastic data set, the variation in Y differs depending on the value of X. In this example, small values of X yield small scatter in Y while large values of X result in large scatter in Y.
