For left-skewed: Mean>Median - This is because majority of the high-value data points are stacked while low-value data points are sparse 
For Right-skewed: Mean<Median - This is because majority of the low-value data points are stacked while high-value data points are sparse 

  • Explain right-skew and left-skew distributions (draw on whiteboard). Where are mean and median values in these cases, compared to symmetrical normal bell shape?
  • How would you describe right-skewed and left-skewed distributions, and where do the mean and median lie in each case compared to a normal distribution?
  • Can you illustrate the differences between right-skewed and left-skewed distributions, particularly where the mean and median are placed in contrast to a normal distribution?
  • Explain the concept of skewness in distributions. Where would you typically find the mean and median in right-skewed and left-skewed distributions?
  • Show how the mean and median are positioned in right-skewed and left-skewed distributions compared to a normal bell curve.,
  • Describe the characteristics of right and left-skewed distributions and where the mean and median fall in these distributions compared to a normal curve.,
  • In skewed distributions, where do the mean and median fall compared to a normal distribution?
  • Please explain right and left skewness in distributions and the relative positions of mean and median.,
  • Illustrate and explain the differences in the placement of mean and median in right-skewed and left-skewed distributions, as opposed to a normal distribution.,
  • Define right-skewed and left-skewed distributions. Where would you find the mean and median in these distributions compared to a normal distribution?
  • Could you explain the characteristics of right-skewed and left-skewed distributions and their mean and median positions relative to a normal distribution?
