Chapter 1: descriptive research method study play descriptive research methods scientific procedures that involve systematically observing behavior in order to describe the relationship among behaviors and events naturalistic observation. Most common type of descriptive research may utilize questionnaires, interviews, or observational techniques to collect date cross-sectional survey design a single group of respondents is surveyed. The descriptive techniques discussed above permit a statement, in the form of correlations, about that relationship however, correlation does not imply causation that is, simply because two events are in some way correlated (related) does not mean that one necessarily causes the other. Descriptive research is conclusive in nature, as opposed to exploratory this means that descriptive research gathers quantifiable information that can be used for statistical inference on your target audience through data analysis.
Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques quantitative research focuses on gathering. Descriptive research may be defined as a purposive process of gathering, analyzing, classifying, and tabulating data about prevailing conditions, practices, beliefs, processes, trends, and cause-effect relationships and then making adequate and accurate interpretation about such data with or without the aid of statistical methods. Descriptive research methods in psychology from georgia institute of technology this is a five-section course as part of a two-course sequence in research methods in psychology this course deals with descriptive methods and the second course.
Descriptive market research and exploratory market research are often categorized as distinct approaches to conducting research studiesand, while that is fundamentally true, it is important to recognize that the two approaches to market research are highly complementary and considerable value can be achieved by using the two approaches together. Case studies, surveys, naturalistic observation, and laboratory observation are examples of descriptive or correlational research methodsusing these methods, researchers can describe different events, experiences, or behaviors and look for links between them. There are a variety of descriptive research methods available, and once again, the nature of the question that needs to be answered drives which method is used.
Descriptive science is a category of science that involves descriptive research that is, observing, recording, describing, and classifying phenomena descriptive research is sometimes contrasted with hypothesis-driven research , which is focused on testing a particular hypothesis by means of experimentation. The difference between descriptive research and experimental research is about manipulation in descriptive design, variables of the study are already existing and only need to be observed. This article explains the difference between descriptive and inferential statistic methods in short, descriptive statistics are limited to your dataset, while inferential statistics attempt to draw conclusions about a population.
Introduction to quantitative methods parina patel october 15, 2009 contents 1 de nition of key terms 2 or quantitative values 3 2 descriptive statistics objective of the research or hypothesis there are numerous di erent 12 15. Descriptive statistics are used to describe the basic features of the data in a study they provide simple summaries about the sample and the measures together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data. Unlike exploratory research, descriptive research is preplanned and structured in design so the information collected can be statistically inferred on a population the main idea behind using this type of research is to better define an opinion, attitude, or behaviour held by a group of people on a given subject.
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. Other descriptive research methods l developmental research l case study l job analysis l observational research l correlational studies ~developmental research l is the study of changes in behaviors across years. Descriptive research descriptive research seeks to depict what already exists in a group or population an example of this type of research would be an opinion poll to determine which presidential candidate people plan to vote for in the next election.
Descriptive research design what is it research that uses a set of scientific methods and procedures to collect raw data and create data structures that describe the existing characteristics of a defined target population or market structure. Qualitative research is ideal for earlier phases of research projects while for the latter part of the research project, quantitative research is highly recommended quantitative research provides the researcher a clearer picture of what to expect in his research compared to qualitative research. In addition to the methods listed above some individuals also include qualitative (as a distinct method) and archival methods when discussing descriptive research methods.
