Math Problem Statement

Match the distribution shape with the correct relationship in comparing the mean to the median.

Solution

The question asks you to match distribution shapes with the relationship between the mean and the median. Here's how to solve this:

  1. 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.
  2. 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.
  3. 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.

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.
