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
