Detailed Solution for Test: Methods of Data Collection - Question 2

Key Points
Stages of processing of data:
Stage 1: Editing of Data

  • The editing of data is a process of examining the raw data to detect errors and omissions and to correct them, if possible, to ensure legibility, completeness, consistency and accuracy. 
  • The recorded data must be legible so that it could be coded later. An illegible response may be corrected by getting in touch with people who recorded it, or alternatively it may be inferred from other parts of the question.

Stage 2: Coding of Data:

  • Coding is the process of assigning some symbols (either) alphabetical or numerals or (both) to the answers so that the responses can be recorded into a limited number of classes or categories.
  • The classes should be appropriate to the research problem being studied.
  • They must be exhaustive and must be mutually exclusive so that the answer can be placed in one and only one cell in a given category.

Stage 3: Classification of Data:

  • Classification condenses the data, facilitates comparisons, helps to study the relationships and facilitates in statistical treatment of data.
  • The classification should be unambiguous and mutually exclusive and collectively exhaustive.
  • Further, it should not only be flexible but also suitable for the purpose for which it is sought.'
  • Classification can either be according to attributes or numerical characteristics

Stage 4: Tabulation of Data:

  • The tabulation is used for summarization and condensation of data.
  • It aids in analysis of relationships, trends and other summarization of the given data.
  • The tabulation may be simple or complex.
  • Simple tabulation results in one-way tables, which can be used to answer questions related to one characteristic of the data.
  • The complex tabulation usually results in two way tables, which give information about two interrelated characteristics of the data; three way tables which give information about three interrelated characteristics of data; and still higher order tables, which supply information about several interrelated characteristics of data. 

Stage 5: Using Percentages:
The tabulated data is converted into percentages and useful results are drawn from it.
