Introduction to Statistics: Mean, Median, and Mode
The Mean
The first term ‘average’ is something we have been familiar with from a very early age when we start analyzing our marks on report cards. We add together all of our test results and then divide it by the sum of the total number of marks there are. so, statistically it’s the Mean!
=&0=&Example:
Four tests results: 15, 18, 22, 20
The sum is: 75
Divide 75 by 4: 18.75
The ‘Mean’ (Average) is 18.75
The Mode
The mode
