success drivers are product selection‚ website characteristics‚ product pricing‚ and trust element. Accordingly‚ we can order these variables in terms of their impact for instance‚ we may observe from the body of research that the trust element has more weight than product selection in contributing to success thus‚ we can think of those variables as of an ordinal nature. Ordinal data however‚ cannot be measured therefore‚ if we are to construct a survey that would answer particular questions on a

this test is that the distribution of the K-S test statistic itself does not depend on the underlying cumulative distribution function being tested. Another advantage is that it is an exact test (the chi-square goodness-of-fit test depends on an adequate sample size for the approximations to be valid). Despite these advantages‚ the K-S test has several important limitations: 1. It only applies to continuous distributions. 2. It tends to be more sensitive near the center of the distribution than at

(unless there had been a market shock). However based on Central Limit Theorem‚ if the sample size is greater than or equal to 30 samples‚ the sample statistics reflect the time population parameters. • The Median data does not show much in this case as the range (4.7 AA Fly and 6.8 TT Air) is small for both AA Fly and TT Air. This means that the mean is more applicable to be used. • The Mode of AA Fly (7.3) is much nearer to the mean (7.167) compared to TT Air (9.2) which is much further (mean of

Lies of Silence: Personal freedom is not viewed as important here. Throughout the text individuals are forced to do things by others that they do not wish to do‚ or others at least attempt to force them to do so‚ which is still indicative of a world where one’s personal freedom to choose what they wish to do is not valued.

Each plays a different‚ yet very important role in the world of statistic a) Nominal scale Is the lowest level in scales of measurement?
