No attempt made to manipulate variables, but rather to observe "as is". It is an affordable way to conduct research. Most research can be divided into three different categories: exploratory, descriptive and causal. research questions, paired sample t-test, ANOVA analysis, and least significant difference (LSD) test were used. Methodology In order to get a comprehensive background for understanding the current knowledge in research methods for qualitative and quantitative methodologies we adopted a narrative literature review. Allows investigation of variables in more real-world . correlational, descriptive, and experiential. The research can utilize methods such as surveys, observation, field experiments, interviews and number analysis. Both descriptive and inferential statistics rely on the same set of data. These characteristics do not indicate that there are correct ways to do QD studies; rather, they demonstrate how others designed and produced QD studies. Descriptive Research Design provides explanation and examples for quantitative descriptive research.A closed-captioned version of this video is available here.. Descriptive research is distinct from correlational research, in which researchers formally test whether a relationship exists between two or more variables. Strengths of Descriptive research. operational, experimental, and descriptive. Cost-effective and fast. 3 Confidentiality. Experimental research provides conclusions that are specific. In writing the literature review, our purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are.

Some of the significant advantages of descriptive research are: Data collection: A researcher can conduct descriptive research using specific methods like observational method, case study method, and survey method. Answer the "what", not the "why". The direction of the linear relationship is indicated by the sign of the correlation coefficient. For instance, information on prevalence of cataract in a city may help the government decide on the appropriate number of ophthalmologic facilities. Experimental research goes a step further beyond descriptive and . It is possible to determine success or failure, making it possible to understand the validity of a product, theory, or idea in a much . Each of these research methods has unique strengths and weaknesses, and each method may only be appropriate for certain types of research questions. This article reviews the essential characteristics, describes strengths and weaknesses, discusses methodological issues, and gives our recommendations on design and statistical analysis for cross-sectional studies in pulmonary and critical care medicine. Experimental research tests cause and effect, while non-experimental research, such as, correlation research, relates variables, and survey research describes trends. The review evolved during the planning stage of a PhD project that sought to determine the effects of witnessed resuscitation on bereaved relatives. The research design should be carefully developed to ensure that the results are valid and reliable.. Strengths of this approach include: Replication Repeating the study is possible because of standardized data collection protocols and tangible definitions of abstract concepts. Finding relationships between variables is the goal of corr View the full answer Transcribed image text: What are the relative weaknesses and strengths of descriptive/correlational research as opposed to experimental research? 1. What are the strengths of using descriptive statistics to examine a distribution of scores? Experimental research is a research where the variables are manipulated by the researcher to arrive at conclusions or come across findings.Unlike in the case of descriptive research, in experimental research, the focus is not on describing the population; testing the hypothesis is the main focus.There are different types of experiments such as quasi-experiments . .

Descriptive statistics rely solely on this set of data, whilst inferential statistics also rely on this data in order to make generalisations about a larger population. Descriptive research refers to research which describes a phenomenon or else a group under study. Weaknesses: Studies are expensive and time-consuming.. Challenges include limited resources for situating the methodology, challenges in employing a lesser-known methodology, and uncertainty regarding the degree of . . Descriptive Research: Assessing the Current State of Affairs Descriptive research is designed to create a snapshot of the current thoughts, feelings, or behaviour of individuals. Strengths: Descriptive research can provide an in-depth view of any topic we might want to study, and the level of detail that we can find in descriptive research is extremely valuable. Research works can be done via two methods. They are useful for establishing preliminary evidence in planning a future advanced study. Exposure data often only available at the area level. Descriptive research does not rely on only one type of data; it relies on both quantitative and qualitative research. blurted this. Differences in exposure between areas may be bigger than at the individual level, and so are more easily examined. Descriptive research is usually defined as a type of quantitative research, though qualitative research can also be used for descriptive purposes.

This advantage reduces the risk of having bias creep into the information being gathered. 1 Data Collection. There are three basic types of quantitative research questions: descriptive research questions, correlational research questions, and causal research questions. 3. Observe values of two or more variables and determine what relationships exist. Each serves a different end purpose and can only be used in certain ways. Moreover, all researchers presented focused or comprehensive, descriptive summaries of data including themes or categories answering their research questions. Companies can collect data first-hand based on stats and unbiased information. Video 1. Raw data would be difficult to analyze, and trend and pattern determination may be .

Let's do a quick overview of all three types of research . Companies use descriptive research analysis, but it has both advantages and disadvantages. Compared to exploratory and explanatory case study designs: Strengths are that descriptive case study focuses on illuminating a phenomenon, it does not be limited to a part of bigger research. The weakness is there are no generalizations about the data and the results are not 100% accurate. In this form of research, we may find information that we never even knew to . What are the strengths of descriptive research methods? Descriptive Research: Assessing the Current State of Affairs Descriptive research is designed to create a snapshot of the current thoughts, feelings, or behaviour of individuals. Limitations and Weaknesses of Quantitative Research: Research entails the collection of materials for academic or other purposes. Differentiate between descriptive, experimental, and correlational research Explain the strengths and weaknesses of case studies, naturalistic observation, and surveys There are many research methods available to psychologists in their efforts to understand, describe, and explain behavior and the cognitive and biological processes that underlie it. Because experimental research provides such a high level of control, it can produce results that are specific and relevant with consistency. Importance of Descriptive Statistics. 3. Often subjects are not truthful as they feel the need to tell the researcher what they think the researcher might want to hear. research techniques (Martin & Bridgmon, 2012; Hoy & Adams, 2015).

ADVANTAGES OF DESCRIPTIVE RESEARCH gives researchers the opportunity to use both quantitative and qualitative data in order to find data and characteristics about the population or phenomenon that is being studied, The data collection for descriptive research presents a number of advantages as it can provide a very multifaceted approach. Descriptive research is distinct from correlational research, in which psychologists formally test whether a relationship exists between two or more variables.
