If we have studied statistics, we will assimilate the significance of n (n = representation size). When your representation distance is tiny or biased, the accuracy of your deduction or inference or end will be of singular accuracy.
The normal tallness of Malaysians
There have been 5 adult males in your house. You magnitude their heights as well as find out which the normal tallness is 1.55 m. Your n = 5. If, formed upon this, we explain which the normal tallness of adult males in Malaysia is 1.55m, your matter is not credible.
Now we go out as well as magnitude the heights of 10 adult males any in all fourteen states. Your n = 140. You find out which the normal tallness of the adult males in your representation is 1.62m. If, formed upon this, we explain which the normal tallness of adult males in Malaysians is 1.62m, your matter is still not convincing though some-more correct than the progressing matter formed upon n=5.
The subsequent day we go out as well as magnitude the heights of 1000 adult males any in all fourteen states. Your n = 14,000. You find out which the normal tallness of your representation is 1.58m. If, formed upon this, we explain which the normal tallness of adult males in Malaysians is 1.58m, the credit of your matter improves though might still not good enough to be statistically valid [14000 is less than 1% of adult males in Malaysia].
Then there is the issue of representativeness of your representation is. If your representation consists of usually state basketball players, then we can contend which your representation is skewed or biased. Or if we picked usually those men aged 60 as well a! s above, we can additionally contend which your representation is inequitable i.e. the representation does not paint the population.
Now we go out as well as magnitude the heights of 10 adult males any in all fourteen states. Your n = 140. You find out which the normal tallness of the adult males in your representation is 1.62m.

The n (and the representativeness) is really important. The credit of the conclusions depends upon it.
People who consider open ride in Malaysia is efficient
You live in KL as well as there have been 4 others in your household. You ask all 4 whether the open ride in Malaysia is efficient? If dual of them contend yes, as well as the alternative dual contend no, can we explain which 50% of Malaysians contend which the open ride in Malaysia is efficient? Of march not. Your representation distance is too tiny as well as as the result your end not credible.
Now we go out as well as talk 200 commuters during the Bukit Jalil LRT station. 140 determine which open ride is efficient, 60 contend no. Based upon this survey, can we explain which 70% of Malaysian determine which open ride is efficient? Of march not. Your representation is tiny as well as biased. The representation is inequitable because it is singular to people already regulating the LRT which is not deputy of the race of Malaysia (heck it is not even deputy of people in the Kelang Valley).
Now we go as well as talk 10,000 people in Melaka as well as an additional 10,000 in Sarawak as well as ask the same question. If 33% of the 20,000 respondents contend which they consider open ride in Malaysia is efficient, can we interpretation which 33% of Malaysians consider! open ri de is efficient? Of course, not. The representation is tiny (20,000 is still less than 0.1% of Malaysians) as well as inequitable (focussing upon Melaka as well as Sarawak only)
To get convincing results, we need to have sure the representation distance is vast enough as well as it is representative. We must have sure respondents have been from all over Malaysia. Key demographic as well as socio-economic factors which could influence the outcomes must be considered in the choice of sample. Income is the good example. Individual income might be an critical cause in determining whether one uses open ride or not. If your representation consists of all tall income earners, the results of your consult will not be deputy of the Malaysian population. If your representation usually consists of people vital in urban areas, your conclusions will not be really credible. If your representation usually consists of professionals, your commentary additionally cannot be used to infer to the race of Malaysia as the whole.
n is really important. The credit of the conclusions depends upon it.
Moral of the story
Whenever we have the matter or come to the end about sure people, issues or things, please pause the impulse as well as ask yourself, what is my n? When we contend many Malaysians feel this way, what is your n? When we explain many people adore Rosmah, what is your n? When we scream which many Malaysians have been indignant with BN, what is your n? When we shout which many Malaysians have been indignant with Pakatan, what is your n? When we contend which many Malaysians await "Pakatan Rakyat", what is your n? When we contend many Malaysians awai! t PTPTN, what is your n? When we contend many students have been burdened by PTPTN, what is your n?

Monyet King additionally says
The Malaysian race is current about 28 million. Just 0.1% is 280,000 people.
Have we listened the saying "birds of the feather, flock together". Well, birds of the plume mostly consider comparison too (this is my conclusion, n = 1).
