Types of data analysis for quantitative research

This allows for more accurate findings across a greater spectrum of respondents. Researcher has a clearly defined research question to which objective answers are sought. It is important to note that regression analysis are like correlations in that causation cannot be inferred from the analyses.

When conducted on a single group survey research is its own category. Scales of Measurement module for more information on the scales of measurement. Reviews the literature -- review scholarship on the topic, synthesizing key themes and, if necessary, noting studies that have used similar methods of inquiry and analysis.

Quantitative Social Research Methods.

Types of Data

The most common type of graph for quantitative data is the histogram. Remember, correlation does not always mean causation. Hypothesis testing is used by businesses when determining the probability of an event happening under specific conditions.

A variable can have a positive or negative influence, and the strength of the effect can be weak or strong. The mode most commonly occurring value is 3, a report of satisfaction.

As always the use of statistical analysis is engaged to synthesize the data in a clear method for presentation. Explain the techniques you used to "clean" your data set. Like correlations, causation can not be inferred from regression.

A histogram is a bar graph that is constructed by arranging the data into ranges. An important thing to remember when using correlations is that a correlation does not explain causation. This is usually expressed in a percentage.

Note where key gaps exist and how your study helps to fill these gaps or clarifies existing knowledge. Did they affirm predicted outcomes or did the data refute it? Regression Regression is an extension of correlation and is used to determine whether one variable is a predictor of another variable.

Sharpe, ; Quantitative Research Methods. The best quantitative research gathers precise empirical data and can be applied to gain a better understanding of several fields of study. Colorado State University; Singh, Kultar. For some studies, descriptive statistics may be sufficient if you do not need to generalize the results to a larger population.

Limitations -- describe any limitations or unavoidable bias in your study and, if necessary, note why these limitations did not inhibit effective interpretation of the results. For example, a regression analysis may indicate to you whether or not participating in a test preparation program results in higher ACT scores for high school students.

Longman, ; McNabb, David E. These tools are useful for analyzing survey results, historical data or financial numbers. A researcher will represent and manipulate certain observations that they are studying.

Quantitative Data Types and Tests

Researcher uses tools, such as questionnaires or computer software, to collect numerical data. If two statements were placed in different piles, we would use a 0. For example, the test scores of two groups of students are examined and proven to be significantly different. They will also determine and what the changes may reflect.

The most common type of graph for quantitative data is the histogram. A descriptive study is governed by the following rules: Finally, the type of data analysis will also depend on the number of variables in the study. Quantitative and Qualitative Approaches. Once the information is compiled it is then analyzed mathematically to draw conclusions about the affect that one has on the other.

They can also be used for forecasting or determining the probability of a particular event happening.

Types Of Quantitative Research for Students and Researchers

These tools provide analysts with statistical methods of organizing and examining data. In addition to the basic methods described above there are a variety of more complicated analytical procedures that you can perform with your data.

Statistical analysis -- how did you analyze the data? The best ways to do this are by constructing frequency and percent distributions A frequency distribution is an organized tabulation of the number of individuals or scores located in each category see the table below.

Quantitative research can be exciting and highly informative.quantitative data is that which can be expressed numerically and is associated with a measurement scale not all numbers constitute quantitative data (e.g.

tax file number!) DATA TYPES. Quantitative research, is defined as a the systematic investigation of phenomena by gathering quantifiable data and performing statistical, mathematical or computational techniques.

Learn more about quantitative research methods along with types and examples, characteristics and advantages. Also learn about primary and secondary quantitative research along with techniques and types of.

Jun 09,  · Quantitative research is focused specifically on numerical information, also known as ‘data.’ Because the research requires its conductor to use mathematical analysis to investigate what is being observed, the information collected must be in wsimarketing4theweb.com: April Klazema.

Analyzing Quantitative Research. The following module provides an overview of quantitative data analysis, including a discussion of the necessary steps and types of statistical analyses. In quantitative data analysis you are expected to turn raw numbers into meaningful data through the application of rational and critical thinking.

Quantitative data analysis may include the calculation of frequencies of variables and differences between variables.
