Why do we use Averages? Explain the benefit of using averages. Is there any limitations of it. Long que/ans
Answers
Answer:
WE USE AVERAGES FOR COMPARISONS ACROSS DIFFERENT CLASSES
AVERAGES ARE USEFUL BECAUSE THEY :
* SUMMARISE A LARGE AMOUNT OF DATA INTO A SINGLE VALUE
* INDICATE THAT THERE IS SOME VARIABILITY AROUND THIS SINGLE VALUE WITHIN THE ORIGINAL DATA
LIMITATIONS
AVERAGES CALCULATE ONLY TYE MEAN AVAILABILITY BUT THEY HIDE THE DISPARITIES IN THE PROCESS. THIS IS THE MAIN LIMITATION OF USING AVERAGES.
LET US CONSIDER TWO COUNTRIES A AND B , EACH HAVING 4 CITIZENS
EDUCATION LEVEL OF CITIZENS
COUNTRY A
CITIZEN 1 : Ph.D
CITIZEN 2 : PRIMARY EDUCATION
CITIZEN 3 : M.Tech
CITIZEN 4 : ILLITERATE
AVERAGE : GRADUATE
COUNTRY B
CITIZEN 1 : B.A.
CITIZEN 2 : B.SC
CITIZEN 3 : B.Tech
CITIZEN 4 : M.B.B.S.
AVERAGE : GRADUATE
FROM THE ABOVE EXAMPLE, WE OBSERVE THAT IN COUNTRY B ALL CITIZENS HAVE THE GRADUATE LEVEL OF EDUCATION. THERE ARE FEWER DISPARITIES IN THIS COUNTRY WHEREAS IN COUNTRY A, HALF THE CITIZENS ARE ILLITERATE OR OF PRIMARY EDUCATION LEVEL WHEREAS THE OTHER HALF ARE DOCTORATES OR POST-GRADUATES. THEREFORE EVEN THOUGH AVERAGE EDUCATION LEVEL OF BOTH A AND B IS GRADUATE LEVEL YET THERE ARE GREAT DISPARITIES BETWEEN THEM.
SO THIS ARE THE LIMITATIONS AND BENEFITS OF AVERAGES

We use averages because they are useful for comparing differing quantities of the same category.
For example, to compute the per capita income of a country, averages have to be used because there are differences in the incomes of diverse people. However, there are limitations to the use of averages. This does not show the distribution of thing between people. For an example, suppose in a country, the annual income of a rickshaw puller is Rs 8,000 while an MNC employee earns an annual package of Rs 12,00,000. The average income of this country, therefore, will be Rs 6,05,000. Here actual income or status remains unknown. One can clearly consider this as a rich country thereby ignoring the income disparity between two individuals. Averages are useful for comparison, they also hide disparities.
