AVERAGES

May 06, 2020

MEDIAN, MODE AND MEAN ARE TYPES OF AVERAGE.

MODE-

IT IS THE MOST COMMON NUMBER

1. PUT THE NUMBERS IN ORDER.

2. CHOOSE THE NUMBER THAT APPEARS THE MOST FREQUENTLY.

3. SOMETIMES THERE MAY BE MORE THAN ONE MODE.


EXAMPLE:

CLASS SHOE SIZE: 3, 5, 5, 6, 4, 3, 2, 5, 6

PUT IN ORDER:        2, 3, 3, 4, 5, 5, 5, 6, 6

               THE MODE IS 5

MEDIAN-

IT IS THE MIDDLE VALUE

1. PUT THE NUMBERS IN ORDER.

2. CROSS OFF THE NUMBERS FROM BOTH ENDS OF THE LIST.

3. THE MEDIAN IS THE ONE IN THE MIDDLE.


LET'S TAKE THE SAME EXAMPLE-

PUT IN ORDER:2, 3, 3, 4, 5, 5, 5,6, 6

                      MEDIAN SHOE SIZE  5.


MEAN-

1. ADD ALL THE NUMBERS TOGETHER.

2. DIVIDE THAT ANSWER BY THE AMOUNT OF NUMBERS YOU HAD TO BEGIN WITH.

 ADD TOGETHER: 3+ 5+ 5+ 6+ 4+ 3+ 2+ 1+ 5+ 6 = 40

DIVIDE BY THE AMOUNT WE STARTED WITH: 40 / 10 = 4

                             SO, THE MEAN IS 4.
