DQ1-Week 5: Please respond to this discussion question by Thursday (Day 3):

Does all statistical data have a mean, median, or mode? Why? When is the mean the best measure of central tendency? When is the median the best measure of central tendency?

If there is data that is more than one (hopefully many) there is a mean or the mathematical average, there is a median in odd numbers it is the middle most observed number, if even numbers is the mathematical split between two numbers. This may be different than the average as taken:

Two numbers 45 and 60. The average or mean is (x1x2)/2 which is 105/2 52.5. The median is 45/260/2153.5.

The mode is the value of the number with the highest frequency of occurrence. As in the single array: 4,4,4,7,8,8,9 the mode is 4 as it occurs three...
