Scientists use knowledge about the nature of electrons, protons and neutrons to devise this categorical scheme. We now take for granted the periodic table , yet it took descriptive research to devise it. Descriptive research generally precedes explanatory research. Hence, descriptive research cannot describe what caused a situation. Thus, descriptive research cannot be used as the basis of a causal relationship , where one variable affects another. In other words, descriptive research can be said to have a low requirement for internal validity.
The description is used for frequencies , averages and other statistical calculations. Often the best approach, prior to writing descriptive research, is to conduct a survey investigation. Qualitative research often has the aim of description and researchers may follow-up with examinations of why the observations exist and what the implications of the findings are. In addition, the conceptualizing of descriptive research categorization or taxonomy precedes the hypotheses of explanatory research.
Descriptive research is also known as Statistical Research. The main goal of this type of research is to describe the data and characteristics about what is being studied. The idea behind this type of research is to study frequencies, averages, and other statistical calculations. For this particular research, he can use survey method and also in-depth interviews as data collection methods. However, correlational research is different.
Unlike in the case of descriptive research where the focus is on collecting descriptive data, in correlational research the researcher attempts to identify associations that exist between variables.
The researcher also makes an effort to understand the nature of the relationship as well. However, it is vital to point out that although the researcher identifies whether there is a relationship between factors, he does not manipulate the variables to come to conclusions. He can neither predict which variable influences the other.
For an example, a researcher who studies on suicide can come up with an idea that there is a relationship between teenage suicide and love affairs.
This is a prediction that he makes. However, in a correlational research to identify the connection between variables, the researcher needs to find patterns in his data corpus. This highlights that there exist a clear difference between these two types of research.
Descriptive research methods are pretty much as they sound -- they describe situations. They do not make accurate predictions, and they do not determine cause and effect. There are three main types of descriptive methods: observational methods, case-study methods and survey methods.
Descriptive research is a study designed to depict the participants in an accurate way. More simply put, descriptive research is all about describing people who take part in the study. More simply put, descriptive research is all about describing people who take part in the study.
An important characteristic of descriptive research relates to the fact that while descriptive research can employ a number of variables, only one variable is required to conduct a descriptive study. Three main purposes of descriptive studies can be explained as describing, . descriptive research research that provides an accurate portrayal of characteristics of a particular individual, situation, or group. These studies are a means of discovering new meaning, describing what exists, determining the frequency with which something occurs, and categorizing information.
Descriptive research design is a valid method for researching specific subjects and as a precursor to more quantitative studies. Whilst there are some valid concerns about the statistical validity, as long as the limitations are understood by the researcher, this type of study is an invaluable scientific tool. Some examples of descriptive research include case studies and preliminary observation of a group. Case studies are examples of a relevant event that can be analyzed to learn about a specific group or topic. Observation is an essential part of descriptive research, and is the main way of gathering.
