A cross-sectional study is much more affordable to complete when compared to the other options that are available to researchers today. It is a process of gathering information and data to solve or existing problem or prevent future problems. The weakness is there are no generalizations about the data and the results are not 100% accurate. 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. Results can be compared statistically. qualitative, descriptive, and experimental. Case studies. 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. 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. Strengths: Standardized methods permit the study to be repeated in different areas or over time with the production of comparable findings. 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. What are the strengths of descriptive research methods? Research studies that do not test specific relationships between variables are called descriptive studies. research questions, paired sample t-test, ANOVA analysis, and least significant difference (LSD) test were used. 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 . 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. Survey research allows you to gather large volumes of data that can be analyzed for frequencies, averages . Observe values of two or more variables and determine what relationships exist. Cost-effective and fast. Greater Speculation - Researchers can speculate more on what answers to drill down into and how to approach them. 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. It is an affordable way to conduct research. Quantitative research is widely used in psychology, economics, demography, marketing, political science, and educational studies. This advantage reduces the risk of having bias creep into the information being gathered. Descriptive studies are closely associated with observational studies, but they are not limited with observation data collection method. Descriptive statistics do not allow us to reach to the conclusions beyond the data we have analyzed regarding any hypotheses we might have made. The research can utilize methods such as surveys, observation, field experiments, interviews and number analysis. The strengths and weaknesses of the three principle social scientific research methods of experiment, survey and ethnography are highlighted. descriptive, correlational, and experimental. The research design majorly focuses on explaining more of . More Targeted - This research process can target any area of the business or concern it may have. Companies can collect data first-hand based on stats and unbiased information. Descriptive research requires gathering data that will describe an event and presenting the information in an organized, and often visual, manner. Inferential statistics refers to a sampling of data . Descriptive research does not rely on only one type of data; it relies on both quantitative and qualitative research. 3 Confidentiality Confidentiality is the primary weakness of descriptive research. Non-experimental research can take the following forms: Cross-sectional research: Cross-sectional research is used to observe and analyze the exact time of the research to cover various study groups or samples. 1 Data Collection. While descriptive research can employ a number of variables, only one variable is required to conduct a descriptive study. Strengths of this approach include: Replication Repeating the study is possible because of standardized data collection protocols and tangible definitions of abstract concepts. 3. Weaknesses: Studies are expensive and time-consuming.. 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. Using a descriptive research design requires the use of specific forms of data collection related the process. Companies use descriptive research analysis, but it has both advantages and disadvantages. Moreover, all researchers presented focused or comprehensive, descriptive summaries of data including themes or categories answering their research questions. This type of research is divided into: Descriptive: When values are observed where one or more variables are presented. Two very important of this approach are the following (i) it Descriptive research designs also offer a unique means of data collection in the form of examining life experiences.

Collecting the data from different different organizations in the specific forms of data collection. This can be particularly difficult during in-person interviews. At the end, reviewers summarize the study's key strengths and limitations and their implications for the findings. Both descriptive and inferential statistics rely on the same set of data. Video 2.4.1. This information is useful for resource planning. 2. Log onto the UG Sakai LMS course site: 2. Variables have distributions of its units which can fit mathematical models of data to variable extents. Descriptive research methods are used to define the who, what, and where of human behavior and other . Strengths: Study participants are questioned or observed in a natural setting (e.g., their homes, child care or educational settings). These characteristics do not indicate that there are correct ways to do QD studies; rather, they demonstrate how others designed and produced QD studies. The three main categories of research are. Descriptive statistics refers to the underlying data and does not draw conclusions about the data being represented. Inferential statistics refers to a sampling of data, and does not refer to a whole data set. 3. 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. This information is usedto develop the correlational, descriptive, and experiential. A literature review is an account of what has been published on a topic by accredited scholars and researchers. What are the strengths of descriptive design? Descriptive research designs also offer a unique means of data collection. Qualitative research or quantitative research. entire group of interest to researchers to which they wish to generalize their findings What is a sample? Descriptive Statistics Descriptive statistics is the analysis of data that summarize data in a way such that meaningful patterns emerge from the data. 01. Descriptive research is distinct from correlational research, in which psychologists formally test whether a relationship exists between two or more variables. Strengths identified include a coherent logic and structure, an orientation toward the generation of practice-relevant findings, and attention to disciplinary biases and commitments. Its strength lies in the ability to involve several subjects at a single point in time to achieve data saturation. The results apply to various other topics and departments, too. 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. Descriptive research is a systematic search for a specific topic to come up with new and useful information. What are the advantages and disadvantages of descriptive research? Surveys. Each serves a different end purpose and can only be used in certain ways. The weakness is there are no generalizations about the data and the results are not 100% accurate. Descriptive research is a multifaceted research approach. Applied research is one type that is used to answer a specific question with direct application. Each of the three research designs varies according to its strengths and limitations, and it is important to understand how each differs. This type of research requires the model performance to be monitored on a constant basis in order to ensure its compliance with the original hypotheses. Advantages and disadvantages of descriptive research In addition, it obtains information on the phenomenon or situation to be studied, using techniques such as observation and survey, among others. The design applies to measuring study variables that cannot be manipulated in the lab. Most research can be divided into three different categories: exploratory, descriptive and causal. Observational method. 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. Importance of Descriptive Statistics. 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. Descriptive research is distinct from correlational research, in which psychologists formally test whether a relationship exists between two or more variables. It can also be used for many different purposes, which makes it a very versatile method of gathering data. Strengths of Descriptive research. Check Answer. Answer the "what", not the "why". This paper presents a critical review of the strengths and weaknesses of research designs involving quantitative measures and, in particular, experimental research. operational, experimental, and descriptive. Expert Answer A nswer The goal of descriptive research is to offer a snapshot of the existing situation. What is Experimental Research? They can use instinct and subjective experience to identify and extract good data. Allows investigation of variables in more real-world . Limitations and Weaknesses of Quantitative Research: Research entails the collection of materials for academic or other purposes. 3. Descriptive research is easy to do in social sciences due to manipulating variables. Each of the three research designs varies according to its strengths and limitations, and it is important to understand how each differs. This is particularly true of descriptive research that is collected qualitatively. The strengths are you can clarify large volumes of data with no uncertainties. 1. 2. 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. In this form of research, we may find information that we never even knew to . 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. Let's look closer at one type of qualitative research- phenomenological research - and its strengths and limitations. Each of the methods used to collect descriptive data have their own strengths and limitations. Let's do a quick overview of all three types of research . First, surveys are an excellent way to gather lots of information from many people. We'll examine both in this section. Descriptive studies are useful for estimating the burden of disease (e.g., prevalence or incidence) in a population. It can include quantitative data such as the use of empirical information, or can depict qualitative sources such as patterns of disease. Recap. Answer (1 of 2): Descriptive statistics is formally an approach to defining the modes of variability of a measurable quantity. blurted this. No attempt made to manipulate variables, but rather to observe "as is". Differences in exposure between areas may be bigger than at the individual level, and so are more easily examined. For each, the relative emphasis placed on the setting, reliability, generalizability, description of explanatory variables and control of extraneous is summarized. 2.0 INTRODUCTION.
