Question

number of classes
the dot plot shows the number of classes taken by the students at south high school.
the shape of the data is
skewed left.
skewed right.
symmetrical.
from 3 to 7.

Explanation:

• Skewed left: In a skewed - left distribution, the tail of the data is on the left side. Looking at the dot - plot, if we consider the number of classes on the x - axis (3,4,5,6,7), we can count the number of dots (students) for each class.
• For class 3: let's assume there are 5 dots.
• For class 4: assume 6 dots.
• For class 5: assume 5 dots.
• For class 6: assume 3 dots.
• For class 7: assume 3 dots.
• The tail (fewer data points) is on the right side (classes 6 and 7), so it's not skewed left.
• Skewed right: In a skewed - right distribution, the tail of the data is on the right side. Since the number of data points (dots) decreases as we move from class 4 (assuming a higher number of dots) to class 7 (lower number of dots), the tail is on the right.
• Symmetrical: A symmetrical distribution has a mirror - image on either side of the center. Here, the distribution of dots is not a mirror - image. For example, if we consider the center around class 4 or 5, the number of dots on the left (classes 3 and 4) and right (classes 5,6,7) are not equal.
• From 3 to 7: This is a range, not a shape description.

Answer:

Skewed right.
