The measurement and coding of the data for the thesis Thesis No Comments

The measurement and coding of the data means the processing thereof. Before completing this phase of the thesis, it is required that the previous steps of the methodological design of the research work have been completed. This includes the selection of the sample, the adequacy of the data collection method and, of course, the creation of the registration instrument.

It is very important to proceed in an orderly and logical manner. Do not skip operations, or omit any element. Likewise, before starting, we must ensure that we have clear variables to study and that we have all the resources and support to carry out the measurement.

WHAT DOES IT MEASURE TO MEASURE?

Measuring the data consists in assigning a value or property according to the purposes of the thesis. To measure different instruments can be used, which will depend on the methodological design that has been chosen for the study. For example, in experimental designs the measurement will be made according to the characteristics of the experiment that the researcher has developed. We must remember that in this type of methodology who proposes and performs the experiment controls the environment, in order to obtain a certain response or record the behavior and evolution of a situation. This in conditions caused intentionally by the researcher.

On the other hand, in non-experimental designs the researcher does not intervene, he only observes and records the data product of the study without manipulation of a certain subject. In these cases, the use of questionnaires and interviews is very frequent and the measurement is made from the coding of answers.

CODING

The response coding is to assign a symbol and then proceed to construct a more detailed analysis, than a simple answer count. This coding is a preparatory step for the analysis and, it is very useful, when it will be carried out with the help of a computer.

Also, the coding allows to categorize the incorrect answers or the lack of them as lost values. The incorrect answers will be presented when the respondents choose mutually exclusive categories or when the given answer has no logical relation to the proposed question.

Another code is the non-application (“not applicable”) that is used when certain questions can not be answered by certain participants. For example: if we conducted a survey of a group of students in the philosophy career and one of the questions is: During the last semester did you study any subject related to the philosophy of Immanuel Kant? And could you indicate which works you studied? The respondent who answers no to the first question obviously does not apply to answer the second question.

As can be seen, the coding serves to better establish the relevance of the answers and prepare them better for interpretation.

This procedure also serves to assign values ​​to the response alternatives, which are symbolized by a number, in order to keep the corresponding record. For example:

Are you a smoker?

Yes = 1 and No = 2

Are you satisfied with the policies of coexistence of the company?

Very satisfied = 5, Satisfied = 4, Neither satisfied nor dissatisfied = 3, Dissatisfied = 2 and Very dissatisfied = 1.

When the respective codes have been established for each answer or alternative, a record is made with their respective variables to create a database. This will serve to observe the similarities found during the measurement process and reach the results phase.
