Sampling Distribution – Normal, Positive or Negative Skewed
Normal Distribution
When the mean is equal to the median and mode, the sampling distribution is deemed to be normally distributed.
Positively Skewed or Right Skewed
When the mean is more than the median, most of the data is concentrated on the left and hence the data is skewed towards the right.
Negatively Skewed or Left Skewed
When the mean is more than the median, most of the data is concentrated on the left and hence the data is skewed towards the right.
