Box Plot Skew Right. Feb 18 2017 We can also identify the skewness of our data by observing the shape of the box plot. For a right skewed distribution the mean is typically greater than the median.
If the longer part of the box is to the right or above the median the data is said to be skewed right. In a symmetrical distribution the mean median and mode are all equal. A few items fail immediately and many more items fail later.
The boxplot with left-skewed data shows failure time data.
Most of the wait times are relatively short and only a few wait times are long. In this case the mode is the highest point of the histogram whereas the median and mean fall to the right of it or visually the right of the peak. It means the data constitute higher frequency of high valued scores. This condition is equivalent to where is the quartile skewness coefficient.
