Mean, median and mode


Here is another learning session with me. Let's understand the concept of three different types of central tendency. Below are the list of central tendencies:

  1. Mean
  2. Median
  3. Mode

Mean, median and mode are the three different types of central tendencies which is helped in the calculation of data. Again there are three different types of mean: arithmetic mean, geometric mean and harmonic mean. Next time i will help you with some other concept such as statistics formulas. This learning session will help you get quality statistics help online.

GET YOUR FRACTIONS HELP HERE


TODAY'S POST IS BASED ON COMPARING FRACTIONS.

COMPARING FRACTIONS IS NOTHING BUT COMPARING TWO FRACTIONS IN CASE WHICH ONE IS THE GREATEST , SMALLEST AND IF THE FRACTIONS ARE EQUAL. IN ORDER TO COMPARE FRACTIONS, WE FIRST NEED TO SIMPLIFY FRACTIONS TO THE SIMPLEST FORM AND THEN COMPARE. BELOW IS GIVEN AN EXAMPLE IN THIS CONCEPT.

EXAMPLE 1: COMPARE 3/12 AND 2/8:
3/12 = 1/4 AND 2/8 = 1/4
THEREFORE, 3/12 = 2/8

EXAMPLE 2: COMPARE 2/4 AND 3/18:
2/4 = 1/2 AND 3/18 = 1/6
NOW, (2X3)/ 12 = 6/12 = 1/2AND (3X4)/ 12 = 12/ 12 = 1
=1/2 < 1
THEREFORE, 2/8 > 3/12

FOR MORE HELP ONE CAN CONNECT TO AN ONLINE TUTOR AND GET THE REQUIRED HELP. NOT JUST FRACTIONS BUT YOU CAN GAIN HELP FROM CALCULUS TUTORING AS WELL.
