Data analysis procedures in quantitative research

More importantly, a regression will tell you whether a variable e. Basics of qualitative research: It is only by doing this that researchers realize how difficult the task is, and this realization affects their expectations when asking others to transcribe.

You'll need your username and password to login. Qualitative research measures, in hopes of developing universal laws where qualitative research can be described as an exploration of what is assumed to be a dynamic reality.

These are more complex analyses and are looking for significant differences between variables and the sample groups of the population. What is the value of aggregation function F over a given set S of data cases? However the data are being collected, a primary responsibility of the researcher is to safeguard participants and their data.

When using pre-existing statistical data gathered and made available by anyone other than yourself [e. Results The finding of your study should be written objectively and in a succinct and precise format. Analyzing Quantitative Data Analyzing Quantitative Research The following module provides an overview of quantitative data analysis, including a discussion of the Data analysis procedures in quantitative research steps and types of statistical analyses.

The data is usually gathered using structured research instruments. A variable can have a positive or negative influence, and the strength of the effect can be weak or strong. In this article, we review some principles of the collection, analysis, and management of qualitative data to help pharmacists interested in doing research in their practice to continue their learning in this area.

The results are then expressed as exact numbers and allow you to begin to give meaning to the data. Describes the theoretical framework -- provide an outline of the theory or hypothesis underpinning your study. The choice of analyses to assess the data quality during the initial data analysis phase depends on the analyses that will be conducted in the main analysis phase.

Facts by definition are irrefutable, meaning that any person involved in the analysis should be able to agree upon them. Smith 9 suggested a qualitative research method known as interpretative phenomenological analysis, which has 2 basic tenets: As a consequence, the results of quantitative research may be statistically significant but are often humanly insignificant.

In analyzing qualitative data, we seek to discover patterns such as changes over time or possible causal links between variables.

Qualitative and Quantitative Research

The following Slideshare presentation, Quantitative Data Analysis explains the use of appropriate statistical analyses in relation to the number of variables being examined. Data are in the form of numbers and statistics, often arranged in tables, charts, figures, or other non-textual forms.

This background knowledge for the transcriber is especially important in research in which people are using jargon or medical terms as in pharmacy practice. Studies may be univariate, bivariate or multivariate in nature. What was treatment like 30 years ago?

Limitations of Using Quantiative Methods Quantitative methods presume to have an objective approach to studying research problems, where data is controlled and measured, to address the accumulation of facts, and to determine the causes of behavior.

For example, nominal scales where data is coded, as in the case of gender, would not have a mean score. Quantitative studies result in data that provides quantifiable, objective, and easy to interpret results.

Distinguishing fact from opinion, cognitive biases, and innumeracy are all challenges to sound data analysis. Listing the scores in order and counting the number of scores If the number of scores is odd, the median is the number that splits the distribution If the number of scores is even, calculate the mean of the middle two scores Mode — the most common number score or value for a particular variable Depending on the level of measurement, you may not be able to run descriptives for all variables in your dataset.

We provide basic descriptions of each method but encourage you to seek additional information e.

Data analysis

It can be difficult to identify patterns or visualize what the data is showing if you are just looking at raw data.

Hammersley M, Atkinson P. 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.

Organizing Your Social Sciences Research Paper: Quantitative Methods

Wadsworth Cengage, ; Brians, Craig Leonard et al. There are two ways to assess measurement: Persons communicating the data may also be attempting to mislead or misinform, deliberately using bad numerical techniques. For example, the test scores of two groups of students are examined and proven to be significantly different.Analyzing Quantitative Research.

Qualitative Research: Data Collection, Analysis, and Management

The following module provides an overview of quantitative data analysis, including a discussion of the necessary steps and types of statistical analyses. Quantitative evaluation is more easily divided into discrete stages of instrument development, data collection, data processing, and data analysis.

By contrast, in qualitative evaluation, data collection and data analysis are not temporally discrete stages: as soon as the first pieces of data are collected, the evaluator begins the. Quantitative Research Methods Quantitative means quantity which implies that there is something that can be counted.

Quantitative research has been defined in many ways. It is the kind of research that involves the tallying, manipulation or systematic aggregation of quantities of data (Henning, ) John W.

Creswell defined quantitative research. Data analysis has two prominent methods: qualitative research and quantitative research. Each method has their own techniques. 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. INTRODUCTION. In an earlier paper, 1 we presented an introduction to using qualitative research methods in pharmacy practice.

In this article, we review some principles of the collection, analysis, and management of qualitative data to help pharmacists interested in doing research in their practice to continue their learning in this area.
