However the main parts of a table in general are discussed here. The answers will require some analysis if their salient points are to be brought out. When the major emphasis falls on the most recent events, a reverse time order may be used. (or any type of data!) What is the number of students scoring less than 40% marks in aggregate ? The process of placing classified data into tabular form is known as tabulation. It is the most systematic way of presenting numerical data in an easily understandable form. As follows. 60% of 50 = ($$\frac{60}{100}$$ x 50) = 30 (6) Head note: - it is a brief explanatory statement applying to all or a major part of the material in the table, and is placed below the point centered and enclosed in brackets. We have just to count the number of times a particular value is repeated which is called the frequency of that class. (1) Table number: - each take should be numbered. What is the average amount of interest per year which the Company had to pay during this period? It can range from the examination of simple frequencies to the description of events or phenomenon using descriptive statistics, and to the investigation of correlation and causal hypothesis using various statistical tests.

Evaluate the data for the random variable and determine if it exceeds the critical value, c, for the test statistic. 2.       formation of a discrete frequency distribution, Types of Statistical Classifications Chronological Classification, When data are observed over a period of time the type of classification is known as chronological classification. We may consider the following guidelines for tabulation : 1. = 27 – 21 = 6. to 150 cm. In a continuous variable, thus data are obtained by numerical measurements rather than counting. When possible, charts and maps can be used to display results and check for outlying values for a better overview of large datasets. Tabulation helps in drawing the inference from the statistical figures. One table should not be overloaded with details. Serves which can be represented by a discrete variable are called discrete series. • It is an intermediate process between the collection of the data and the statistical analysis. the number of students in each class. Write The Hypothesis For The Chi-square Test For Independence B. Classification and tabulation of data The collected data is usually contained in schedules and questionnaires. So we suggest the aspirants learn and practice as much as required. Total number of candidates selected from state A is approximately what percentage of the total number of candidates selected from state B? Total expenditure of the Company during 2000 For example, if there are two coordinate factors, the table is called a two-way table or bi-variate table; if the number of coordinate groups is three, it is a case of three-way tabulation, and if it is based on more than three coordinate groups, the table is known as higher order tabulation or a manifold tabulation… We finally count the number of bars and get frequency. Since 66 students get 20 and above marks in Chemistry and out of these 21 students get 30 and above marks, therefore to select top 35 students in Chemistry, the qualifying marks should lie in the range 20-30. For example, the unit of measurement is frequently written as a head note, such as ''in thousands'' or ''in million tonne3s or ''in crores'', etc. In year 2004 the number of participating girls is what percent of number of participating boys? This put a bar (vertical line) opposite the particular value to which it elates. As a rule, the first step in the analysis is to classify and tabulate the information collected, or, if published statistics have been employed, rearrange these into new groups and tabulate the new rearrangement.

Moreover, the acquisition date of the IACS data does not allow information to be collected on yields; thus, an alternative data source is needed in order to estimate these important parameters. Thus every theoretically continuous series can never be expected to flow continuously with one measurement touching another without any break in actual observations. What is the ratio of boys and girls for school B over the years 2001-2004 ? 4. In order to facilitate counting prepare a column of tallies''. 2. 5. In addition to the numeric checking of the aggregated data that may be built into the tabulation process, an additional analysis and evaluation of the data are also required.

Number of boys participants in 2004 from school B = 480 The answers will require some analysis if their salient points are to be brought out. It is clear from the table that the number of children varied from 0 to 12. Rows are horizontal arrangements whereas columns are vertical arrangements. 2.

The presentation of data means exhibition of the data in such a clear and attractive manner that these are easily understood and analyzed. Number of girls participants in 2004 = 100 + 140 + 120 + 120 = 480 Cross-tabulation, also known as cross-tab or contingency table, is a statistical tool used for categorical data. Tabulation is based on the type of classification and it may be simple, double or complex. 5. 3. = $$\frac{(288 + 98 + 3.00 + 23.4 + 83)}{(420 + 142 + 3.96 + 49.4 + 98)}$$ x 100 % It is also known as one way tabulation. A variable may be either continuous or discrete. In statistics, classification is the problem of identifying to which of a set of categories (sub-populations) a new observation belongs, on the basis of a training set of data containing observations (or instances) whose category membership is known. Horizontal arrangement of data is called rows and vertical arrangement is called columns. Tabulation Data Interpretation MCQ Quiz Online Test will help the postulates in preparation to concentrate more on areas which carry more weightage of marks. etc.) 4,7,9 are merely numerical unless specified—for example, 4 apples, 7 bananas, and 9 kiwis. Thus we can find out the ways in which the frequencies are distributed. It is shown in below table: Then, answer the folowing (2) Title of the table: - every table must be given suitable title.

A simple formula to obtain the estimate of appropriate class interval, i.e. In the year 1995 which state had the lowest percentage of candidates selected over the candidates appeared? Simple tabulation: If the data is tabulated on one characteristic, then it is called simple tabulation. = Rs. = 25 + 20 + 22 + 36 + 32 + 28 = 163, Total no.of candidates selected from state B = 35 + 30 + 28 + 32 + 40 + 38 = 203, Required % = $$\frac{163}{203} \times 100$$ ≅ 80%. Extracting the data from the IACS system in order to obtain the number of hectares of main crops is not an easy task. Also known as contingency tables or cross tabs, cross tabulation groups variables to understand the correlation between different variables. Ø The main objective of tabulation is to present and interpret complex information in a simple and systematic way. Statistics forms the back bone of data science or any analysis for that matter. • ―Tabulation involves the orderly and systematic presentation of numerical data in a form designed to illustrate the problem under consideration‖-- Conner Table and Tabulation… It may be simple, double or complex depending upon the type of classification.
