In following case mean is less than median.
The scores of students ( out of 100 points ) on a very easy exam in which most scores are high, but a few scores are low.
Note: Mean smaller than median suggests the distribution is skewed left towards the lower numbers making the BULK of the data at the higher numbers.

52.1 Three primary statistics are used to describe a variable's central tendency, defined as the average behavior of the variable. You can use these statistics, known as the mean, the median, and the mode, to draw meaningful conclusions about a variable's past behavior and to predict its future behaviar An investor is considering a stock with the following returns over the past 12 years: Year Annual Return Year Annual Return 12 10 12 The mean, also known as the arithmetic...

stats Q1. Hypothesis testing using a Z test (14 points) A professor has been teaching introductory statistics for many years and the final exam performance (30 points total) has been very consistent from class to class and the scores have been normally distributed. Overall, the whole data base (i.e. population) of final exam scores has a mean (μ) of 20 points and a standard deviation (σ) of 5 points. Because 20 out of 30 is only about 67%, the professor...
