Working with Quadrants Analyze your results – What is the mean height of students in your class? Standard deviation? What is the mean armspan of students in your class? Standard deviation? Sketch lines on your graph to represent these values, separating the values that are below the mean from those that are above the mean. Using the definitions of quadrants shown Quadrant II Quadrant I in the figure to the right, record the number of observations in each Quadrant III Quadrant IV of the quadrants. Quadrant I n(QI) = Quadrant II n(QII) = Quadrant III n(QIII) = Quadrant IV n(QIV) = What conjecture can you make about the distribution of observations in the quadrants and the positive or negative correlation of a set of data? How would the observations be distributed to the quadrants if the relationship were perfectly positively correlated? How would the observations be distributed to the quadrants if the relationship were perfectly negatively correlated?
