In a negatively skewed distribution, the tail extends to the left, indicating that there are a few lower values. As a result, the mode, which is the most frequently occurring value, is typically located to the right of the mean and median. This means that in negatively skewed distributions, the mode is usually higher than both the median and the mean.

What does the distribution look like if the mean mode and median are different?

If the mean, mode, and median are different, the distribution is likely skewed. For instance, if the mean is greater than the median, the distribution may be positively skewed (right-skewed), indicating a tail extending towards higher values. Conversely, if the mean is less than the median, the distribution may be negatively skewed (left-skewed), with a tail extending towards lower values. In both cases, the presence of outliers or a non-symmetrical spread can contribute to these differences.


What direction does the tail face in a positively skewed and what direction in a negatively skewed set of data?

In a positively skewed distribution, the tail faces to the right, indicating that there are a few exceptionally high values pulling the mean upwards. Conversely, in a negatively skewed distribution, the tail faces to the left, reflecting the presence of a few exceptionally low values that pull the mean downwards. This skewness affects the relationship between the mean, median, and mode in each case.

Mode


What is unimodal skewed?

Unimodal skewed refers to a distribution that has one prominent peak (or mode) and is asymmetrical, meaning it is not evenly balanced around the peak. In a right (or positively) skewed distribution, the tail on the right side is longer or fatter, indicating that most data points are concentrated on the left. Conversely, in a left (or negatively) skewed distribution, the tail on the left side is longer, with most data points clustered on the right. This skewness affects the mean, median, and mode of the data, typically pulling the mean in the direction of the tail.


Is it true if a distribution is negatively skewed if the right tail is longer than the left?

No, a distribution is considered negatively skewed if the left tail is longer or fatter than the right tail. In this case, the bulk of the data is concentrated on the right side, with a longer tail extending to the left. A positively skewed distribution, on the other hand, has a longer right tail.

i) Since Mean<Median the distribution is negatively skewed ii) Since Mean>Median the distribution is positively skewed iii) Median>Mode the distribution is positively skewed iv) Median<Mode the distribution is negatively skewed


Can the distribution of the mean median and mode be equal if the are positively skewed or negatively skewed or symmetric?

Not necessarily.


Is Mean is more sensitive to skewness than the median?

If the distribution is positively skewed , then the mean will always be the highest estimate of central tendency and the mode will always be the lowest estimate of central tendency (If it is a uni-modal distribution). If the distribution is negatively skewed then mean will always be the lowest estimate of central tendency and the mode will be the highest estimate of central tendency. In both positive and negative skewed distribution the median will always be between the mean and the mode. If a distribution is less symmetrical and more skewed, you are better of using the median over the mean.

What direction does the tail face in a positively skewed and what direction in a negatively skewed set of data?

In a positively skewed distribution, the tail faces to the right, indicating that there are a few exceptionally high values pulling the mean upwards. Conversely, in a negatively skewed distribution, the tail faces to the left, reflecting the presence of a few exceptionally low values that pull the mean downwards. This skewness affects the relationship between the mean, median, and mode in each case.


For a skewed distribution what is a better indicator of the central tendency?

Mode


In a negatively skewed dist. following statements are true except?

In a negatively skewed distribution, the mean is typically less than the median, and the median is less than the mode. This results in a tail that extends longer to the left. Therefore, any statement claiming that the mean is greater than the median or that the mode is less than the median would be false. Thus, one must be careful to identify which statements accurately reflect the characteristics of negatively skewed distributions.

What is skewed left?

A distribution or set of observations is said to be skewed left or negatively skewed if it has a longer "tail" of numbers on the left. The mass of the distribution is more towards the right of the figure rather than the middle.
