Central Tendency, Skewed Distributions, Discrete and Continuous

Question 1:
When is the mean the best measure of central tendency? When is the median the best measure of central tendency? Explain.

Questions 2:

A researcher has determined that the distribution of annual salaries of NBA players is bell-shaped and symmetrical about the mean salary, do you think that introducing Michael Jordan's last annual salary of more than $30 million would skew this distribution? Explain why or why not. What would be the best measure of central tendency for this distribution? Explain

Question 1:
Give an example representing a discrete probability distribution and a continuous probability distribution. Explain why your choice is discrete and continuous.

Questions 2:

Carefully define a standard normal distribution. Why does a researcher want to go from a normal distribution to a standard normal distribution? Explain.

Solution Summary

This solution answers four questions about central tendency, skewed distributions, discrete and continuous probability distributions and the standrd normal distribution.
