  • The given statement is true. A scatter plot can be used to detect the direction of a relationship between the variables.
  • A scatter plot is formed by plotting the independent variable on the x-axis and the dependent variable on the y-axis.
  • The pattern formed by plotting these points corresponding to their coordinates gives an idea about the correlation present between these variables.
  • If the pattern of dots rises from lower left to upper right , it indicates positive correlation between the variables.
  • If the pattern of dots slopes from upper left to lower right, it indicates negative correlation between the variables.
  • If the pattern neither rises nor falls or first rises, then falls , it indicates the variables are uncorrelated.
