Math Problem Statement
Solution
The image presents a graph showing a skewed distribution, along with three questions asking which labeled point represents the mean, the median, and the mode.
From what I can see:
- The graph is positively skewed (right-skewed), meaning the tail extends to the right. In such distributions:
- The mode is the highest point (the peak) on the graph.
- The median is located between the mode and the mean.
- The mean is typically to the right of the median due to the influence of the skew.
Answering the questions:
-
What letter represents the mean?
- The mean is the rightmost point, labeled C.
-
Which letter represents the median?
- The median lies between the mode and the mean, so it is represented by B.
-
Which letter represents the mode?
- The mode is the highest point of the curve, represented by A.

Related Questions:
- How would this change if the distribution were negatively skewed (left-skewed)?
- Why does the mean get pulled towards the tail in a skewed distribution?
- What are the key differences between mean, median, and mode in symmetric vs skewed distributions?
- How can outliers affect the mean compared to the median?
- In which situations is the median a better measure of central tendency than the mean?
Tip:
In skewed distributions, the median is often used as a better measure of central tendency than the mean, especially when outliers are present.

Theorems
In a positively skewed distribution, the mode is the peak of the distribution, the median is the middle value, and the mean is affected by the tail.
