According to Prof Bowley averages are statistical constants which provide an idea about the concentration of values in the central part of the distribution. The five common measures of central tendency are : 1. Mean [Airthmetic mean] 2. Median 3. Mode 4. harmonic mean 5. Geometric mean According to Prof. Yule following are the characterstics required to measure central tendency: 1. Central tendency should be rigidly defined 2. It should be comprehensive and easy to determine 3. Should be based on all observations 4. It should not be much affected by the fluctuation of sampling 5. It should not be affected by extreme values Let us talk about these distributions in detail: 1. Arithmetic mean: Arithmetic mean of a set of observations can be calculated as their sum divided by the number of observations In case f i is the frequency of variable x i then distribution becomes ' Properties of Arithmetic Mean 1. Algebric sum of deviations of a set of v...

• E-Commerce : electronic commerce was meant for facilitation of commercial transactions electronically, using technology such as Electronic Data Interchange (EDI), Electronic Funds Transfer (EFT), etc • Models of e-commerce : B2B,B2C, C2B AND C2B • EDI: can be stated as collection of standard message formats to exchange data between organizations computers via any electronic service. • SET: is a standard protocol for securing credit card transactions over insecure networks, more specifically addressing transactions over Internet. Please note clearly, SET is not itself a payment system, but rather a set of security protocols • Merchant account: When you want to have credit card, you fill up form/details and submit same to financial institution, on similar lines when some want to start e-business/ online transactions (which need online transaction through credit, debit, charge cards), one must step up a merchant account.

In technical jargons testing is also popularly known as “AT”, i.e. acceptance testing. Success of your website depends on this factor in major way. You should do self (means self) check in order to cross validate, that all things are working properly, for e.g. - Forms filled by users is properly stored in database - Hyperlinks / associate links to work properly - Security related stuff, encryption/ SSL etc totally secure! - Make a accentuate test, to check who much load website can carry Maintenance is ongoing endeavor, which will go long way. After website is through with testing and becomes online, it becomes your moral responsibility to nurture this “new kid on the block”. One has to constantly monitor traffic and evaluate web site activities. Remember most of knowledgeable visitors, check first thing while visiting website is “when it was last updated”, it gives impression that how serious/updated seller is about business ! Also, it’s extremely vital to be innovative for...
