Math Problem Statement
Solution
The question asks you to match distribution shapes with the relationship between the mean and the median. Here's how to solve this:
-
Right-skewed distribution:
- In a right-skewed distribution, the tail extends to the right. The mean is pulled in the direction of the tail, so the mean is typically greater than the median.
-
Left-skewed distribution:
- In a left-skewed distribution, the tail extends to the left. The mean is pulled towards the left, making the mean less than the median.
-
Symmetric distribution:
- In a symmetric distribution, the mean and median are equal because the data is evenly distributed on both sides of the center.
Correct matching:
- Right-skewed: Mean is greater than the median.
- Left-skewed: Mean is less than the median.
- Symmetric: Mean is equal to the median.

- In which real-world scenarios might you encounter a right-skewed or left-skewed distribution?
Tip:
In a skewed distribution, the tail direction helps determine if the mean is greater or less than the median: right-skewed = mean > median, left-skewed = mean < median.
