Bibliography Definition Quantitative methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques.
Quantitative research focuses on gathering numerical data and generalizing it across groups of people or to explain a particular phenomenon. The Practice of Social Research. Wadsworth Cengage, ; Muijs, Daniel. Characteristics of Quantitative Research Your goal in conducting quantitative research study is to determine the relationship between one thing [an independent variable] and another [a dependent or outcome variable] within a population.
Quantitative research designs are either descriptive [subjects usually measured once] or experimental [subjects measured before and after a treatment]. A descriptive study establishes only associations between variables; an experimental study establishes causality.
Quantitative research deals in numbers, logic, and an objective stance. Quantitative research focuses on numeric and unchanging data and detailed, convergent reasoning rather than divergent reasoning [i. Its main characteristics are: The data is usually gathered using structured research instruments.
The results are based on larger sample sizes that are representative of the population. The research study can usually be replicated or repeated, given its high reliability. Researcher has a clearly defined research question to which objective answers are sought.
All aspects of the study are carefully designed before data is collected. Data are in the form of numbers and statistics, often arranged in tables, charts, figures, or other non-textual forms. Project can be used to generalize concepts more widely, predict future results, or investigate causal relationships.
Researcher uses tools, such as questionnaires or computer software, to collect numerical data. The overarching aim of a quantitative research study is to classify features, count them, and construct statistical models in an attempt to explain what is observed.
Things to keep in mind when reporting the results of a study using quantitative methods: Explain the data collected and their statistical treatment as well as all relevant results in relation to the research problem you are investigating. Interpretation of results is not appropriate in this section.
Report unanticipated events that occurred during your data collection. Explain how the actual analysis differs from the planned analysis. Explain your handling of missing data and why any missing data does not undermine the validity of your analysis.
Explain the techniques you used to "clean" your data set. Choose a minimally sufficient statistical procedure; provide a rationale for its use and a reference for it. Specify any computer programs used. Describe the assumptions for each procedure and the steps you took to ensure that they were not violated.Testing Guidelines.
To get faster and more reliable results: Test only a few elements If you change multiple elements on each page, it can be difficult to figure out which element or combination of elements was responsible for the best results.
A variable is any characteristics, number, or quantity that can be measured or counted. A variable may also be called a data tranceformingnlp.com, sex, business income and expenses, country of birth, capital expenditure, class grades, eye colour and vehicle type are examples of variables.
Identify the appropriate place and promotional strategy that should be used in the development of the strategic marketing plan Gentry Identify quantifiable elements that can be used to evaluate, monitor, and control the effectiveness of your marketing plan.
Density as a Characteristic Property The density of a substance is a characteristic of that substance. can be used for clinical research, policy research, and other types of performance evaluation.
