A distribution is said to be positively skewed if it

A distribution is said to be positively skewed if it has a long tail to the right. This means that the distribution has a cluster of data points towards the left side of the graph, and then a long "tail" of data points stretching out towards the right. The mean of a positively skewed distribution is usually greater than the median, which is the middle value of the data set. This is because the long tail on the right side pulls the mean towards higher values.
