Why and what for? QUANTITATIVE DATA

In order to obtain this type of data it is necessary that all the elements of the investigation and the problem can be clearly defined, that is, quantitative data are explicitly defined with numbers , where the problem begins, where it goes and what is its conclusion .

That is, in quantitative research , the approach or input hypothesis, development and conclusions are expressed through numerical data expressed either in frequencies, percentages or statistics in general.

In other words, quantitative data allows you to measure or calculate something within the investigation. When used, they make it easy to read actual results ; since these, support the hypothesis and everything that arises.

Thus, we can say at the moment in which there are statistics regarding the investigated topic, reality can be shown and they are no longer mere theories or hypotheses to induce the presentation of results,  the respective conclusions and even induce recommendations .

Research, based on quantitative data, can be descriptive, analytical or experimental.

  • The experimental group takes the population and divides it into a control group and another study group to be analyzed.
  • The descriptive is the stage in which the scientific work is being prepared, that is, where the procedures and variables are determined for the phenomena to be studied.
  • The analytics, induces the contribution of conclusions. It is more complete because a relationship (comparison) of the variables between the study groups must be established.

For the collection of quantitative data , among the most used instruments are: survey, questionnaire and the census .

In contrast to quantitative data , there are those of a qualitative type , typical of a qualitative research and that in general, are presented in a descriptive way, highlighting or evaluating a quality or attribute and; not a number.

For example:

  • Way of drinking coffee, in the mornings (with milk; red; brown);
  • How does the internet influence the performance of adolescents ?;
  • Relationship between diet, height and weight of a population.
