4. 4. THE DAFFODILS <ul><li>Miss Gee is very excited. “The daffodils” her flower boutique which she had set up two years back is getting an overwhelming response from the customers. It has now emerged among the best flower suppliers in the neighborhood. The reason for this success is the undaunting effort by Miss Gee. She makes it a point to sell fresh flowers of all the possible varieties including the seasonal flowers at justified and affordable price. Her invaluable customer service has earned her many regular customers. </li></ul>
5. 5. But at the same time she is finding it difficult to keep track of the total sales in each category of flowers. She indeed has all the copies of the sales bills. In order to increase her total sales she has to find out which of her flowers have more demand. For this she needs to review the past sales trend. But she is piled up with all the bills. How do you think she has to sort out the bills? Yes!!! She has to first classify the flower into different groups.
6. 6. CLASSIFICATION <ul><li>DEFINITION </li></ul><ul><li>The act of forming into a class or classes, a distribution into groups, as classes, orders, families, etc, according to some common relations or affinities. </li></ul>When studying a number of objects or observations you can sometimes reveal an underlying structure of the material by grouping the observations into classes. For the basis of categorization you have to select a property or attribute which you can record for each of the studied specimens or cases.

15. 15. <ul><li>Other classifications </li></ul><ul><li>Cluster analysis: Cases or specimens for which </li></ul><ul><li>there are lot of measurements but one cannot </li></ul><ul><li>know which of the variables are best suited </li></ul><ul><li>for the basis of classification. </li></ul>
16. 16. <ul><li>Other classifications </li></ul><ul><li>Classification of people: In cases of people , </li></ul><ul><li>families, and organizations, classes are made </li></ul><ul><li>on the basis of profession, education, income </li></ul><ul><li>and other demographic characteristics. </li></ul>
17. 17. TABULATION <ul><li>Definition </li></ul><ul><li>Tabulation is the process of summarizing classified or grouped data in the form of a table so that it is easily understood and an investigator is quickly able to locate the desired information. </li></ul>
18. 18. Objectives of Tabulation <ul><li>It simplifies complex data and the data presented are easily understood. </li></ul><ul><li>It facilitates comparison of related facts. </li></ul><ul><li>It facilitates computation of various statistical. </li></ul><ul><li>It presents facts in minimum possible space. </li></ul><ul><li>Moreover, the needed information can be easily located. </li></ul><ul><li>Tabulated data are good for references and to present the information in the form of graphs and diagrams. </li></ul>
19. 19. Components of Table <ul><li>An ideal table should consist of the following main parts: </li></ul><ul><li>Table number </li></ul><ul><li>Title of the table </li></ul><ul><li>Captions or column headings </li></ul><ul><li>Stubs or row designation </li></ul><ul><li>Body of the table </li></ul><ul><li>Footnotes </li></ul><ul><li>Sources of data </li></ul>
