Quantitative Research and Analysis: Quantitative Methods Overview

Research design refers to the overall strategy utilized to carry out research [1] that defines a succinct and logical plan to tackle established research question s through the collection, interpretation, analysis, and discussion of data. The methodologies and methods incorporated in the design of a research study will depend on the standpoint of the researcher over their beliefs in the nature of knowledge see epistemology and reality see ontology , often shaped by the disciplinary areas the researcher belongs to.

The design of a study defines the study type descriptive, correlational, semi-experimental, experimental, review, meta-analytic and sub-type e. There are many ways to classify research designs. Nonetheless, the list below offers a number of useful distinctions between possible research designs.

A research design is an arrangement of conditions or collection. Sometimes a distinction is made between "fixed" and "flexible" designs. In some cases, these types coincide with quantitative and qualitative research designs respectively, [6] though this need not be the case. In fixed designs, the design of the study is fixed before the main stage of data collection takes place.

Fixed designs are normally theory-driven; otherwise, it is impossible to know in advance which variables need to be controlled and measured. Often, these variables are measured quantitatively.

Flexible designs allow for more freedom during the data collection process. One reason for using a flexible research design can be that the variable of interest is not quantitatively measurable, such as culture. In other cases, the theory might not be available before one starts the research.

The choice of how to group participants depends on the research hypothesis and on how the participants are sampled. In a typical experimental study, there will be at least one "experimental" condition e.

Confirmatory research tests a priori hypotheses — outcome predictions that are made before the measurement phase begins. Such a priori hypotheses are usually derived from a theory or the results of previous studies. The advantage of confirmatory research is that the result is more meaningful, in the sense that it is much harder to claim that a certain result is generalizable beyond the data set. The reason for this is that in confirmatory research, one ideally strives to reduce the probability of falsely reporting a coincidental result as meaningful.

Exploratory research, on the other hand, seeks to generate a posteriori hypotheses by examining a data-set and looking for potential relations between variables. It is also possible to have an idea about a relation between variables but to lack knowledge of the direction and strength of the relation. If the researcher does not have any specific hypotheses beforehand, the study is exploratory with respect to the variables in question although it might be confirmatory for others.

The advantage of exploratory research is that it is easier to make new discoveries due to the less stringent methodological restrictions. In other words, if the researcher simply wants to see whether some measured variables could be related, he would want to increase the chances of finding a significant result by lowering the threshold of what is deemed to be significant. Sometimes, a researcher may conduct exploratory research but report it as if it had been confirmatory 'Hypothesizing After the Results are Known', HARKing [7] —see Hypotheses suggested by the data ; this is a questionable research practice bordering on fraud.

A distinction can be made between state problems and process problems. State problems aim to answer what the state of a phenomenon is at a given time, while process problems deal with the change of phenomena over time. Examples of state problems are the level of mathematical skills of sixteen-year-old children, the computer skills of the elderly, the depression level of a person, etc.

Examples of process problems are the development of mathematical skills from puberty to adulthood, the change in computer skills when people get older, and how depression symptoms change during therapy. State problems are easier to measure than process problems. State problems just require one measurement of the phenomena of interest, while process problems always require multiple measurements.

Research designs such as repeated measurements and longitudinal study are needed to address process problems. In an experimental design, the researcher actively tries to change the situation, circumstances, or experience of participants manipulation , which may lead to a change in behaviour or outcomes for the participants of the study.

The researcher randomly assigns participants to different conditions, measures the variables of interest and tries to control for confounding variables. Therefore, experiments are often highly fixed even before the data collection starts. In a good experimental design , a few things are of great importance. First of all, it is necessary to think of the best way to operationalize the variables that will be measured, as well as which statistical methods would be most appropriate to answer the research question.

Thus, the researcher should consider what the expectations of the study are as well as how to analyse any potential results. Finally, in an experimental design, the researcher must think of the practical limitations including the availability of participants as well as how representative the participants are to the target population. It is important to consider each of these factors before beginning the experiment.

The researcher has an advantage of minimizing resources in experimental research designs. Non-experimental research designs do not involve a manipulation of the situation, circumstances or experience of the participants. Non-experimental research designs can be broadly classified into three categories. First, in relational designs, a range of variables are measured.

These designs are also called correlation studies because correlation data are most often used in the analysis. Since correlation does not imply causation , such studies simply identify co-movements of variables. Correlational designs are helpful in identifying the relation of one variable to another, and seeing the frequency of co-occurrence in two natural groups see Correlation and dependence.

The second type is comparative research. These designs compare two or more groups on one or more variable, such as the effect of gender on grades. The third type of non-experimental research is a longitudinal design. A longitudinal design examines variables such as performance exhibited by a group or groups over time eee Longitudinal study. Famous case studies are for example the descriptions about the patients of Freud, who were thoroughly analysed and described.

This type of research is involved with a group, organization, culture, or community. Normally the researcher shares a lot of time with the group. Grounded theory research is a systematic research process that works to develop "a process, and action or an interaction about a substantive topic". From Wikipedia, the free encyclopedia.

Types of Research

Published on June 20, by Shona McCombes. Revised on June 19, There are many ways to categorize different types of research. The words you use to describe your research depend on your discipline and field. In general, though, the form your research design takes will be shaped by:.


and report some relationships among different aspects of the phenomenon under study. As defined in previous section, the main objective of the.


Research design

There are a number of approaches used in this research method design. The purpose of this chapter is to design the methodology of the research approach through mixed types of research techniques. The research approach also supports the researcher on how to come across the research result findings.

Descriptive research does not fit neatly into the definition of either quantitative or qualitative research methodologies, but instead it can utilize elements of both, often within the same study. The term descriptive research refers to the type of research question, design, and data analysis that will be applied to a given topic. Descriptive statistics tell what is, while inferential statistics try to determine cause and effect. The type of question asked by the researcher will ultimately determine the type of approach necessary to complete an accurate assessment of the topic at hand. Descriptive studies, primarily concerned with finding out "what is," might be applied to investigate the following questions: Do teachers hold favorable attitudes toward using computers in schools?

Before beginning your paper, you need to decide how you plan to design the study. The research design refers to the overall strategy that you choose to integrate the different components of the study in a coherent and logical way, thereby, ensuring you will effectively address the research problem; it constitutes the blueprint for the collection, measurement, and analysis of data. Note that the research problem determines the type of design you should use, not the other way around! De Vaus, D. Research Design in Social Research. Research Methods Knowledge Base. The function of a research design is to ensure that the evidence obtained enables you to effectively address the research problem logically and as unambiguously as possible.

Research design is the framework of research methods and techniques chosen by a researcher. The design allows researchers to hone in on research methods that are suitable for the subject matter and set up their studies up for success. There are three main types of research design: Data collection, measurement, and analysis. The type of research problem an organization is facing will determine the research design and not vice-versa. The design phase of a study determines which tools to use and how they are used. An impactful research design usually creates a minimum bias in data and increases trust in the accuracy of collected data. A design that produces the least margin of error in experimental research is generally considered the desired outcome.

The purposes and criteria for formulating a design of research, conditions for judging causality, and use of research design as a control of variance are discussed. The purpose of a research design is to provide a plan of study that permits accurate assessment of cause and effect relationships between independent and dependent variables. The classic controlled experiment is an ideal example of good research design. Factors that jeopardize the evaluation of the effect of experimental treatment internal validity and the generalizations derived from it external validity are identified. Sources of variance can be controlled by eliminating a variable, randomization, matching, or including a variable as part of the design. A research project should be so designed that 1 it answers the questions being investigated, 2 extraneous factors are controlled, and 3 the degree of generalization that can be made is valid. Abstract The purposes and criteria for formulating a design of research, conditions for judging causality, and use of research design as a control of variance are discussed.

It is the statement of essential elements of a study that provides basic guidelines of conducting the project. The research design is similar to broad plan or model that states how the entire research project would be conducted. It is desirable that it must be in written form and must be simple and clearly stated. The real project is carried out as per the research design laid down in advance. Research design is a broad framework that states the total pattern of conducting research project.

 Сколько угодно, - улыбнулась женщина.  - Самолет улетел почти пустой. Но завтра в восемь утра тоже есть… - Мне нужно узнать, улетела ли этим рейсом моя подруга. Она собиралась купить билет прямо перед вылетом. Женщина нахмурилась: - Извините, сэр.

 Я из отдела испанской полиции по надзору за иностранными туристами. В вашем номере проститутка. Немец нервно посмотрел на дверь в ванную. Он явно колебался. - Ja, - признался он .
