To solve for the variation in data you take the ____________________ between the maximum and minimum. {Ans: To solve for the variation in data you take the difference between the maximum and minimum. For the treatment group this is equal to 2.24−(−1.19)=3.43; for the placebo group this is equal to 0.78−(−2.29)=3.07. 3.07 is less than 3.43, Therefore the placebo group has less variation in its data.}An ______________________* in a scatterplot is a point that does not fit the overall trend of the other points. It is usually far away from the other points and is easy to spot. There may be more than one outlier, but if several points are grouped together away from the majority of points, we call them a_________________*, not outliers. Consider the following scatterplot: {Ans: Outlier* Cluster*}The pattern of points tells us about the strength of the correlation between the variables. If the points form a ___________ _____________ pattern, we say there is a strong correlation between the variables. If the points are ________________ scattered and are not tightly grouped, we say there is a weak correlation or no correlation between the variables {Ans: tightly grouped pattern* weak correlation* or no correlation between
