Descriptive research does not rely on only one type of data; it relies on both quantitative and qualitative research. 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. It is an affordable way to conduct research. descriptive, correlational, and experimental. The weakness is there are no generalizations about the data and the results are not 100% accurate. correlational, descriptive, and experiential. The following are some of the strengths and limitations of descriptive research studies in general. Each of the three research designs varies according to its strengths and limitations, and it is important to understand how each differs. What are the strengths of using descriptive statistics to examine a distribution of scores? Descriptive research is easy to do in social sciences due to manipulating variables. Strengths: Standardized methods permit the study to be repeated in different areas or over time with the production of comparable findings. Recap. 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. Descriptive research requires gathering data that will describe an event and presenting the information in an organized, and often visual, manner. Let's look closer at one type of qualitative research- phenomenological research - and its strengths and limitations. 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. 2 Life Experiences. Inferential statistics refers to a sampling of data, and does not refer to a whole data set. Advantages of Descriptive Studies Descriptive (including ecological) studies are generally relatively quick, easy and cheap to conduct. What are the disadvantages of descriptive? 2.0 INTRODUCTION. Observing variables as they exist in "nature". More Targeted - This research process can target any area of the business or concern it may have. . 1 Data Collection. There are three basic types of quantitative research questions: descriptive research questions, correlational research questions, and causal research questions. This information is useful for resource planning. For example, research studying the morphology and mechanism of action of SARS-CoV-2 is descriptive. Descriptive research is a research design that is used to investigate different phenomenon and situations. The strengths are you can clarify large volumes of data with no uncertainties. Strengths identified include a coherent logic and structure, an orientation toward the generation of practice-relevant findings, and attention to disciplinary biases and commitments. They are useful for establishing preliminary evidence in planning a future advanced study. Each of these research methods has unique strengths and weaknesses, and each method may only be appropriate for certain types of research questions. part of population that is studied to reach conclusions about population Between these three, all primary data collection methodsare covered, which provides a lot of information. Each of these research methods has unique strengths and weaknesses, and each method may only be appropriate for certain types of research questions. No attempt made to manipulate variables, but rather to observe "as is". The research can utilize methods such as surveys, observation, field experiments, interviews and number analysis. A cross-sectional study is much more affordable to complete when compared to the other options that are available to researchers today. operational, experimental, and descriptive. Both descriptive and inferential statistics rely on the same set of data. 1. In medical research, a cross-sectional study is a type of observational study design . Answer the "what", not the "why". Descriptive studies are useful for estimating the burden of disease (e.g., prevalence or incidence) in a population. Survey research, as with all methods of data collection, comes with both strengths and weaknesses. Depending on the nature of the study, a researcher can use any of the following four main types of quantitative research, namely: Descriptive Research, Correlational Research, Causal-Comparative Research or Quasi-Experimental Research, and Experimental Research. A literature review is an account of what has been published on a topic by accredited scholars and researchers. It allows for data to be presented in a meaningful and understandable way, which, in turn, allows for a simplified interpretation of the data set in question. 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 psychologists formally test whether a relationship exists between two or more variables.Experimental research goes a step further beyond descriptive and . Most research can be divided into three different categories: exploratory, descriptive and causal. This can be particularly difficult during in-person interviews. Surveys. Two very important of this approach are the following (i) it Expert Answer A nswer The goal of descriptive research is to offer a snapshot of the existing situation. Weaknesses: Studies are expensive and time-consuming.. 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. 3. Strengths of survey methods Researchers employing survey methods to collect data enjoy a number of benefits. Descriptive research methods. In the online survey world, mastery of all three can lead to sounder insights and greater quality information. The strengths are you can clarify large volumes of data with no uncertainties.

What are the advantages and disadvantages of descriptive research? 3. Greater Speculation - Researchers can speculate more on what answers to drill down into and how to approach them. Moreover, all researchers presented focused or comprehensive, descriptive summaries of data including themes or categories answering their research questions. Quantitative research is widely used in psychology, economics, demography, marketing, political science, and educational studies. Exposure data often only available at the area level. You need less time for performing such types of research. Go to Descriptive Statistics in Psychology Ch 14. supporting their assessment. This information is usedto develop the Descriptive research is distinct from correlational research, in which psychologists formally test whether a relationship exists between two or more variables. The three main categories of research are. Its strength lies in the ability to involve several subjects at a single point in time to achieve data saturation. It is mainly classified into two types: basic or fundamental research and applied research. Descriptive research designs also offer a unique means of data collection in the form of examining life experiences. blurted this. Because experimental research provides such a high level of control, it can produce results that are specific and relevant with consistency. 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. They can use instinct and subjective experience to identify and extract good data. Strengths: Study participants are questioned or observed in a natural setting (e.g., their homes, child care or educational settings). 01. This type of research is divided into: Descriptive: When values are observed where one or more variables are presented. The weakness is there are no generalizations about the data and the results are not 100% accurate.

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? Descriptive research is usually defined as a type of quantitative research, though qualitative research can also be used for descriptive purposes. Often subjects are not truthful as they feel the need to tell the researcher what they think the researcher might want to hear. Research studies that do not test specific relationships between variables are called descriptive studies. The strengths of case study research are it provides rich descriptive information that can lead to further study, has a narrow focus, combines objective and subjective data, is process-oriented and is a good source of hypotheses. The pros: It's the best way to collect data without bias. Surveys. 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 of this approach include: Replication Repeating the study is possible because of standardized data collection protocols and tangible definitions of abstract concepts. 2.

Descriptive statistics do not allow us to reach to the conclusions beyond the data we have analyzed regarding any hypotheses we might have made. Descriptive statistics allow for the ease of data visualization. The key benefits of exploratory research design are: Increased Understanding: The main objective of exploratory research is to improve a researcher's knowledge of a topic. The most common statistical measure of the strength of linear relationships among variables is the Pearson correlation coefficient, which is symbolized by the letter r. The value of the correlation coefficient ranges from r = -1.00 to r = +1.00. Let's do a quick overview of all three types of research .
