Quantitative Methods: Meaning and Characteristics

characteristics of quantitative research

Data gathered using this type of survey is from people who depict similarity in all variables except the variables which is considered for research. Researcher expertise: Poor knowledge of the application of statistical analysis may negatively affect analysis and subsequent interpretation Black, 1999. Qualitative research is multimethod in focus, involving an interpretive, naturalistic approach to its subject matter. This sampling technique is implemented where the target population is considerably large. The trend at this time tends more to the functionality or utility of the method. If the observations are not repeatable, both results and conclusions are considered to be unreliable.

In addition, preconceived expectations preclude the researcher from observing subtle nuances of character and speech that may be important to understand group behaviors or interactions. They seek answers to questions that stress how social experience is created and given meaning. Some researchers say that validity and reliability are co-related, but the validity is much more important than reliability. Quantitatively based are widely used in the media, with statistics such as the proportion of respondents in favor of a position commonly reported. The output serves as the basis for making the conclusions and generalizations of the study. This test gives weight to the study.

Tree-ring width, for example, is considered a reliable proxy of ambient environmental conditions such as the warmth of growing seasons or amount of rainfall. While the qualitative research relies on verbal narrative like spoken or written data, the quantitative research uses logical or statistical observations to draw conclusions. Survey Research: is the most fundamental tool for all quantitative research methodologies and studies. Nursing research, 17 4 , 364. This research method involves the collection of from existing data sources like the internet, government resources, libraries, research reports etc. Empirical Political Analysis: Quantitative and Qualitative Research Methods.

Exploring Characteristics of Qualitative Research

characteristics of quantitative research

Conversely, in quantitative research measurable data is gathered. Hypotheses can also be tested because of the used of statistical analysis Antonius, 2003. In quantitative studies, it is common to use graphs, tables, charts, and other non-textual elements to help the reader understand the data. Typically, results from qualitative research have been assumed to apply only to the small groups studied, such that generalizability of the results to other populations is not expected. A descriptive study is governed by the following rules: subjects are generally measured once; the intention is to only establish associations between variables; and, the study may include a sample population of hundreds or thousands of subjects to ensure that a valid estimate of a generalized relationship between variables has been obtained.

The approach does not need to be tested by existing theories; on the contrary, it seeks to produce new theories. For example, a or closed questions on a questionnaire would generate quantitative data as these produce either numerical data or data that can be put into categories e. This combination of quantitative and qualitative data gathering is often referred to as. The term qualitative research usually reminds us of a data collection processed without the use of any statistical or mathematical operation. Methods Non-structured techniques like In-depth interviews, group discussions etc. This characteristic of qualitative research causes the variable sampling for this type of study to be much smaller to work with than the larger and more complex samples used in quantitative researches. The issue of quality in qualitative research.

The distinct feature of is that the researcher focuses on collecting data directly rather than depending on data collected from previously done research. It is said that it is better coupled with researchers who truly care about the subject, want to take it seriously and are willing to commit to the study. Colorado State University; Yin, Robert K. Useful for testing and validating already constructed theories. Keep figures small in size; include graphic representations of confidence intervals whenever possible. Notice that qualitative data could be much more than just words or text.

Below are the three key elements that define a qualitative research study and the applied forms each take in the investigation of a research problem. Alternatively, qualitative approaches focus on how and why something works, to build understanding. Differences Between Qualitative and Quantitative Research Methods. Structured techniques such as surveys, questionnaires and observations. Qualitative research often opens up new options and ideas that quantitative research cannot due to its closed-ended nature. Existing data is summarized and collated to increase the overall effectiveness of research.

Hypotheses and theories can continuously change depending on what the observer wants to know. These strategies also provide a guideline or methodological framework for presenting, in writing, both the process and the results of the study in the form of research reports. In the positivist model, study objects eg, learners are independent of the researchers, and knowledge or facts are determined through direct observations. These commercial information sources have in-depth, first-hand information on economic developments, political agenda, market research, demographic segmentation and similar subjects. Four types of measurement scale exist namely nominal, ordinal, ratio, and interval see. A scientific and empirical research method that is used to generate numerical data, by employing statistical, logical and mathematical technique is called quantitative research. This is because accepting a theory based on results of quantitative data could prove to be a natural phenomenon.
