the test scores of the students in three different classes are represented by the dot plots below

drag each classes listed below to the box where it belongs so that it matches the descriptions of the statistics
the class with the lowest mean
the class with the highest mean
the classes with the smalliest standard deviation
class A, class B, class c

To classify the classes based on their means and standard deviations using dot plots, you'll generally need to look for the following characteristics:

  1. Mean: This is the average score of the class. To determine which class has the lowest and highest mean, observe the center of the distribution of scores in each dot plot.

  2. Standard Deviation: This is a measure of how spread out the scores are. A smaller standard deviation means that the scores are closer to the mean and less varied. To identify the class with the smallest standard deviation, look for the dot plot where the scores are clustered tightly around the mean.

Without seeing the actual dot plots, I can't provide specific classifications. However, here's an outline of how you might go about organizing the classes:

  1. Class with the lowest mean:

    • Drag the class with the lowest center point on its dot plot to this box.
  2. Class with the highest mean:

    • Drag the class with the highest center point on its dot plot to this box.
  3. Classes with the smallest standard deviation:

    • Drag the class with the tightest clustering of scores around its mean to this box.

If you provide the characteristics of each class or describe the dot plots, I can aid you further in identifying where to place each class.
