Introduction Statistics is a set of tools used to organize and analyze data. Data must either be numeric in origin or transformed by researchers into numbers. For instance‚ statistics could be used to analyze percentage scores English students receive on a grammar test: the percentage scores ranging from 0 to 100 are already in numeric form. Statistics could also be used to analyze grades on an essay by assigning numeric values to the letter grades‚ e.g.‚ A=4‚ B=3‚ C=2‚ D=1‚ and F=0. Employing

universally. The scale is chosen depending on the information that the data is intending to represent. The four scales of measurement of data are nominal‚ ordinal‚ interval‚ and ratio. Each plays a different‚ yet very important role in the world of statistic a) Nominal scale Is the lowest level in scales of measurement? Is a way of grouping behavior‚ where actual numbers are simply labels or identifiers. -they do not put subjects in any particular order: no logical basis for the answers in each

a plot of the empirical distribution function with a normal cumulative distribution function for 100 normal random numbers. The K-S test is based on the maximum distance between these two curves. Characteristics and Limitations of the K-S TestAn attractive feature of 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

The primary role of statistics is to to provide decision makers with methods for obtaining and analyzing information to help make these decisions.

Premium Sampling Statistics Stratified sampling
suggested measuring skewness by standardizing the difference between the mean and the mode‚ that is‚ . Population modes are not well estimated from sample modes‚ but one can estimate the difference between the mean and the mode as being three times the difference between the mean and the median (Stuart & Ord‚ 1994)‚ leading to the following estimate of skewness: . Many statisticians use this measure but with the ‘3’ eliminated‚ that is‚ . This statistic ranges from -1 to +1. Absolute values above

shorter than TT Air‚ it does not significantly affect the output as the one day does not change much (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
