Consider the many possible distributions of grades on a quiz in a statistics class; imagine that the grades could range from 0 to 100. For each of the following situations, give a hypothetical mean and median (that is, make up a mean and a median that might occur with a distribution that has this shape). Explain your answer. a. Normal distribution b. Positively skewed distribution c. Negatively skewed distribution Solution The parameter µ is the mean or expectation (location of the peak) and s?2 is the variance. s is known as the standard deviation. The distribution with µ = 0 and s?2 = 1 is called the standard normal distribution or the unit normal distribution. , Hypothetical Mean=60 \" Median=70.
