Detailed explanation-1: -Right skewed: The mean is greater than the median. The mean overestimates the most common values in a positively skewed distribution. Left skewed: The mean is less than the median.
Detailed explanation-2: -The distribution of scores on any particularly difficult exam will be positively skewed with most students scoring around some mean value with a few outlier students scoring much higher.
Detailed explanation-3: -An example of a real-life variable that has a skewed right distribution is salary. Most people earn in the low/medium range of salaries, with a few exceptions (CEOs, professional athletes etc.) that are distributed along a large range (long “tail”) of higher values.
Detailed explanation-4: -Answer and Explanation: FALSE. If the exam were truly easy, this means that most students would get a high score. The mean would be on the right, which means that we should expect a negatively skewed distribution instead.
