MEAN, MEDIAN, AND MODE
Mean, Median, and Mode are ways to measure the central tendency of a set of numbers.
Mean
Mean, better known as average, is the most common way to find central tendency. It is found by adding all the numbers in a set together, then dividing the sum by the amount of numbers originally in the set.
Median
Median means the middle number. Median is found by ordering all the numbers given from least to greatest.
Next if the amount of numbers is odd, there would be one median and if it was an even amount, there would be 2. In a case where the total amount of numbers are even you would have to find the average of the two medians. (Find the Mean of the two Medians.)
Next if the amount of numbers is odd, there would be one median and if it was an even amount, there would be 2. In a case where the total amount of numbers are even you would have to find the average of the two medians. (Find the Mean of the two Medians.)
Mode
When you are finding mode, you find the number that occurs the most in a number sequence, If the numbers all occur the same amount, there is no Mode.
