It explains what the column represents it may consist of one or more column headings. The title is a description of the contents of the table. (324 + 101 + 3.84 + 41.6 + 74) lakhs Quantitative Analysis – is employed on data that have been assigned some numerical value. Rows are horizontal arrangements whereas columns are vertical arrangements. It is also known as one way tabulation. The answers will require some analysis if their salient points are to be brought out. 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. In order to facilitate counting prepare a column of tallies''. Required ratio = 1480 : 400 = 37 : 10, 5. 3. Classification of tables. The total amount of bonus paid by the Company during the given period is approximately what percent of the total amount of salary paid during this period? So organisation of data is essential. However the main parts of a table in general are discussed here. 2. 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. The number may be given either in the centre at the top above the title or inside of the title at the top or in the bottom of the table on the left hand side. $\frac{(23.4 + 32.5 + 41.6 + 36.4 + 49.4)}{5}$ lakhs INTRODUCTION The classification of data leads to the problem of presentation of data. 2. 3. The term variable refers to the characteristic that varies in amount of magnitude in a frequency distribution. Tabulation may be defined as systematic presentation of data with the help of a statistical table having a number of rows and columns and complete with reference number, title, description of rows as well as columns and foot notes, if any. Ø The tabulation involves a systematic arrangement of data (information) in the form of rows and columns. Tabulation is the simplest way of arranging the data, so that anybody can understand it in the easiest way. Required Percentage = ($\frac{21}{73}$ x 100)% = 28.77% = 29%. Get Academic Excellence with Best Skilled Tutor! It is the systematic arrangement of raw data … the number of students in each class. 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 difference between the number of students passed with 30 as cut-off marks in Chemistry and those passed with 30 as cut-off marks in aggregate? = $\frac{(288 + 98 + 3.00 + 23.4 + 83)}{(420 + 142 + 3.96 + 49.4 + 98)}$ x 100 % = 1720, 3.

In Economics we deal with a lot of data about the economy and its components. It uses data to learn — constructing algorithms and programs that collect from various sources and apply hybrids of mathematical and computer science methods to derive deeper actionable insights. (4) Stub: - as distinguished from caption, studs are the designations of the rows or row heading. 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. For example, we may present the figures of population (or production, sales. Percentage increase = $\frac{(480 – 280)}{280}$ x 100% = 71%, 4. 1. When the major emphasis falls on the most recent events, a reverse time order may be used. The following are two examples of discrete and continuous frequency distributions: Formation of a discrete frequency distribution. In other cases these processes, though may materially assist the analysis, are not sufficient presentation of the facts. Sound knowledge of statistics can help an analyst to make sound business decisions. Number of students getting at least 60% marks in Chemistry = Number of students getting 30 and above marks in chemistry = 21. As compared with the main part of the table the caption should be shown in smaller letters. 5. 544.44 lakhs, 5. .The data is recorded in the form of a table. = $\frac{495.4}{713.36}$ x 100 % ≅ 69.45%. Evaluate the data for the random variable and determine if it exceeds the critical value, c, for the test statistic. The answers will require some analysis if their salient points are to be brought out. As follows. = 27 – 21 = 6. Tabulation is mainly based on the data concerning common disciplines as production over a period of a few years like imports, exports, incomes of employees in a factory, students applying for and qualifying for a certain field of study etc..T The data is recorded in the form of a table. But that is not in an easily assailable form.

Complex tabulation: If the data is tabulated on many characteristics, then it is called complex tabulation. Also known as contingency tables or cross tabs, cross tabulation groups variables to understand the correlation between different variables. for example, the students of a college may be classified to weight as follows: Such a distribution is known as emperical frequency distribution or simple frequency distribution. Under a column heading there may be sub-heads. 3. Frequency distribution of the number of children*. Types of tabulation: They are three types. Practice Problem: A statistician has created the cross tabulation below using data collected in a random survey. 3. A frequency distribution refers to data classified on the basis of some variable that can be measured such as prices, wages. 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. Statistics, the science of collecting, analyzing, presenting, and interpreting data.Governmental needs for census data as well as information about a variety of economic activities provided much of the early impetus for the field of statistics. In singular form, the word means the statistical methods with the help of which collection, analysis and interpretation of data are accomplished. To facilitate counting, blokes of five bars are prepared and some space is left in between each block. Number of girls participating in 2004 = 100 + 140 + 120 + 120 = 480 Study the following table carefully and answer the questions given below it: There are 50 students having weight ranging from 90 to 100 lb, 200 students having weight ranging from 100 to 110 lb, and so on.
