# tabulation of data in statistics problems

(or any type of data!) 2. = $$\frac{451}{586}$$ It is shown in below table: Then, answer the folowing Cross tabulation is a statistical tool that is used to analyze categorical data. They are at the extreme lift and perform the same function for the horizontal rows of numbers in the table as the column headings do for the vertical columns of numbers. The process of placing classified data into tabular form is known as tabulation. Number of girls participants in 2004 = 100 + 140 + 120 + 120 = 480 = $$\frac{(288 + 98 + 3.00 + 23.4 + 83)}{(420 + 142 + 3.96 + 49.4 + 98)}$$ x 100 % In this type of classification, there are two elements, namely (I) the variable. Infertility. This type of analysis is crucial in finding underlying relationships within your survey results. (PSSC: 2001: 51) 13. Number of students getting at least 40% marks in aggregate = Number of students getting 20 and above marks in aggregate = 73. 5. A frequency distribution refers to data classified on the basis of some variable that can be measured such as prices, wages. 4. The caption should be clearly defined and placed at the middle of the column, if the different columns are expressed in different units. 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… Number of students getting at least 60% marks in Chemistry = Number of students getting 30 and above marks in chemistry = 21. The answers will require some analysis if their salient points are to be brought out. Double tabulation: If the data is tabulated on the two characteristics at a time, then it is called double tabulation. (5) Body: - the body of the table contains the numerical information. Thus we can find out the ways in which the frequencies are distributed. Categorical data involves values that are mutually exclusive to each other. 2. 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. One table should not be overloaded with details. For example, when a student grows, sat, from 90 cm. What is the ratio of boys and girls for school B over the years 2001-2004 ? Demonstrate problem and solution use of t-Tests. Simple tabulation: If the data is tabulated on one characteristic, then it is called simple tabulation. We finally count the number of bars and get frequency. Statistics forms the back bone of data science or any analysis for that matter. As we told you our team of expert, they are best in their field and we are always live to help you in your assignment which makes it special.Key features of services are listed below: Experts are helping students not just improving grades but also to provide better learning of subject concepts and its problem statements. thus we can find out the ways in which the frequencies are distributed. There were 2 families with no child, 5 families with 4 children and only one family with 12 children. 4. As follows. Introduction. However the main parts of a table in general are discussed here. It is used to explain certain points relating to the whole table that have not been included in the title nor in the cations or studs. 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? The presentation of data means exhibition of the data in such a clear and attractive manner that these are easily understood and analyzed. Also known as contingency tables or cross tabs, cross tabulation groups variables to understand the correlation between different variables. = Rs. Tabulation is the simplest way of arranging the data, so that anybody can understand it in the easiest way. (7) Footnotes: - anything in a table which the reader may find difficult to understand from the title, captions and studs should be explained in footnotes. .The data is recorded in the form of a table. As compared with the main part of the table the caption should be shown in smaller letters. Required ratio = 480 : 1710 = 16 : 57, 2. During which of the following years the passing percentage over appeared is the highest from state D? Practice Problem: A statistician has created the cross tabulation below using data collected in a random survey. It facilitates a clear and simple presentation of the data, a clear expression of the implication, and an easier and more convenient comparison. Special tabulation by NCHS . 4.
