This document discusses the preparation of a frequency distribution table from a discrete data series. It provides an example of survey data from 20 homes on the number of cars registered to each household. The data is organized into a frequency distribution table with columns for the number of cars, tally marks, and frequencies. The table shows that 0 cars were recorded 3 times, 1 car was recorded 4 times, 2 cars 6 times, and so on, with the total of all frequencies equaling the 20 total data points. The document also provides the meaning and steps for creating a frequency distribution table, including organizing the data values and tallying the frequency of each value.

It then discusses different types of diagrams used for data presentation, including bar diagrams, pie charts, and two-dimensional diagrams. The key advantages of diagrams over tables are that they can more quickly and easily convey complex ideas in numbers and trends may be more noticeable. Guidelines for effective diagrams include giving them a clear title, using an appropriate size and scale, including a legend if multiple variables are shown, and selecting the correct type of diagram for the data. Common one-dimensional and two-dimensional diagram types are also listed.
KPC skewness 2
This document discusses measures of skewness, including Bowley's coefficient of skewness. It provides examples of calculating Bowley's coefficient using quartiles to determine if a distribution is skewed or symmetrical. The document also includes review questions related to skewness, Bowley's coefficient formula, and examples of its calculation using quartile data from continuous distributions.
Diagrams part 2
This document discusses one dimensional bar diagrams, including simple and subdivided bar diagrams. It provides examples of how to construct simple and component bar diagrams to present statistical data comparing production costs between companies and expenditures across categories for two schools. Multiple choice questions are also included at the end to test understanding of diagrammatic data presentation.
Mean Deviation and Co- efficient
This document discusses quantitative techniques for a B.Com program. It covers measures of central tendency and dispersion such as mean, median, mode, range, mean deviation, standard deviation, and quartile deviation. The learning objectives are to understand these concepts and apply them to sample data. An example is provided to calculate the mean deviation and coefficient of mean deviation from the mean, median, and mode for household income data. Multiple choice questions review key concepts like the definition of mean deviation and properties of variance. References for further reading on statistics are also included.
graphical representation 6
This document discusses quantitative techniques and constructing graphs from data. It covers constructing less than and more than ogive curves, which are cumulative frequency curves. An ogive curve shows the cumulative frequency distribution and can be used to find the median. Two problems are presented on drawing less than and more than ogive curves from data on weights of items and ages of pensioners. Multiple choice questions are also provided to test understanding of ogives and cumulative frequency polygons.
Diagrams part 3
This document discusses quantitative techniques for a B.Com program. It covers one dimensional bar diagrams, including percentage and multiple bar diagrams. It provides examples of problems involving percentage and multiple bar diagrams with solutions. It also includes learning objectives and outcomes about presenting and interpreting data graphically using various charts and diagrams. There are example problems and solutions for constructing percentage and multiple bar diagrams from given data. The document concludes with multiple choice questions and answers about different types of bar diagrams.

Wound healing PPT
This document provides an overview of wound healing, its functions, stages, mechanisms, factors affecting it, and complications.
A wound is a break in the integrity of the skin or tissues, which may be associated with disruption of the structure and function.
Healing is the body’s response to injury in an attempt to restore normal structure and functions.
Healing can occur in two ways: Regeneration and Repair
There are 4 phases of wound healing: hemostasis, inflammation, proliferation, and remodeling. This document also describes the mechanism of wound healing. Factors that affect healing include infection, uncontrolled diabetes, poor nutrition, age, anemia, the presence of foreign bodies, etc.
Complications of wound healing like infection, hyperpigmentation of scar, contractures, and keloid formation.

frequency distribution table 1
- 1. PROGRAMME B.COM SUBJECT QUANTITATIVE TECHNIQUE – I SEMESTER III UNIVERSITY VIJAYANAGAR SRI KRISHNADEVARAYA UNIVERSITY, BALLARI SESSION 08
- 2. RECAP • Types of Classifications and Types of Series (Individual , Discrete & Continuous)
- 3. LEARNING OBJECTIVES • The aim of the chapter is to make students to present data in textual and Tabular format including the technique of creating frequency distribution and working out bi-variate distribution table
- 4. LEARNING OUTCOMES • After the Chapter, The Students Shall be able to Describe and Understand the Rules & Types of Classification, Frequency Distribution, Class Interval & its Types, Basic Principles Tabulation and The Sorting of Data.
- 5. SESSION - 9 • Preparation of Frequency Distribution Table Meaning-- Discrete Series Problems -- 01
- 6. Meaning of Frequency Distribution: • In Statistics, a frequency distribution table is a chart that summarizes values and their frequency, i.e. the number of times the values have occurred. Steps of Frequency Distribution: Four steps they are • we should form table of three columns, with heading of Observations, Tally marks and Frequency. • In the first Column, place all possible values of variables or observations.
- 7. CONT., • In the second column draw tally marks vertically against the observations. After a particular value has occurred four times, for the fifth occurrence we put a cross tally marks IIII ( 5 ) • In the third column (Frequency column) count the number of marks corresponding to each value of the variable and place it. • Discrete or Ungrouped Frequency distribution series In this case, the observations or variables are counted that how many times repeated is called the frequency of that class.
- 8. Example of Discrete Series • Example: A survey was taken on Maple Avenue. In each of 20 homes, people were asked how many cars were registered to their households. The results were recorded as follows: 3,1,4, 0, 2, 1, 5, 2, 1, 5, 4, 2, 3, 2, 0, 2, 1, 0, 3,2. Present this data in Frequency Distribution Table. Ans; Number of Cars Tally marks Frequencies 0 III 3 1 IIII 4 2 IIII I 6 3 III 3 4 II 2 5 II 2 Total 20
- 9. SUMMARY As we already discussed and learnt today on Classifications and Tabulation as below • Preparation of Frequency Distribution Table Meaning-- Discrete Series Problems -- 01
- 10. MCQs 1. In an array, the data are: (a) In ascending order (b) In descending order (c) Either (a) or (b) (d) Neither (a) or (b) 2. The number of tally sheet count for each value or a group is called: (a) Class limit (b) Class width (c) Class boundary (d) Frequency
- 11. MCQs 3. The frequency distribution according to individual variate values is called: (a) Discrete frequency distribution (b) Cumulative frequency distribution (c) Percentage frequency distribution (d) Continuous frequency distribution 4. A series arranged according to each and every item is known as: (a) Discrete series (b) Continuous series (c) Individual series (d) Time series
- 12. MCQs 5. A frequency distribution can be: (a) Qualitative (b) Discrete (c) Continuous (d) Both (b) and (c) ANSWERS 1. C 2. D 3. A 4. C 5. D
