All calculations are possible
Example: Income
🗑
|

| show | is the most frequent value
example: ddccaaa - A is the mode. If these are grades, this shows that it favors smarter students.
🗑
|
||||
| show | is the exact middle of the distribution. N = number of values (state if its even or odd number of values) RANK order before you calculate!
🗑
|
||||
| show | Where mean = median = mode
Note: the tails of the curve represent the outliers with extreme scores for both measures and therefore the highest frequency is clustered around the average.
🗑
|
||||
| show | Where mean>median>mode
Note: long tail to the right means extreme values where this inflates the mean. This means that median encompasses average better than mean.
🗑
|
||||
| show | Where mean<median<mode
Note: long tail to the left means extreme low values which inflate the mean thus we use the median as a measure of central tendency.
