Abstract
The quantitative research is a data research of some hypothesis, which can be checked by using mathematical or statistical techniques. This means employing of some mathematical models and methods (performing calculations). These calculations are based on empirical observations given in a data set. This data has a numeric form.
The qualitative research refers to understanding some phenomena (for example, human behavior) – how and why people do or think something. The quantitative methods are usually can support qualitative researches. The one of the most usual methods to collect the data for qualitative research is to observe a respondent’s impression about some fact.
The Understanding of Quantitative and Qualitative Researches
“In quantitative research, the research question guides the study”. This is because we are checking some statistical hypothesis using certain statistical methods (for example, the hypothesis about equality of means of two different sets of observations). Here the hypothesis may be formulated in the very beginning, and then checked.
"but, in qualitative research, the research findings often emerge from the data." During the qualitative research process (for example, interviewing) some hypothesizes may arrive based on respondents answers. So, the gathering data may give an impression of some laws or rules, and then the hypothesis should be formulated and checked by using quantitative methods.
This claim can be also described in area of Psychology.
Using quantitative and qualitative analyzes can be studied personality. Or quantitative variation- statistical, analysis is to compute the coefficients of the right tasks, the repetition frequency of the observed mental phenomena. To compare the results of different studies on different tasks or quantitative composition of the groups are not absolute, but relative, mainly interest rates. In the quantitative analysis of the results of research are often used arithmetic averages of all the studies of a mental process or individual psychological characteristics. In order to draw conclusions about the likelihood of the arithmetic mean, calculate the coefficient of variation of it separate indicators. With less deviation indicators of individual studies on the arithmetic mean, then it is demonstrative of the psychological characteristics of personality research.
Qualitative analysis is performed on the basis of quantitative analysis, but not confined to it. In the qualitative analysis ascertain the reasons for high or low levels, their dependence on age and individual personality characteristics, living conditions and education, relationships in the team, to the activities, etc.
Quantitative and qualitative analysis of the survey data provide a basis for psychological and educational characteristics of the individual and the findings of educational activities.
