## Data analysis procedures in quantitative research

###
The goal of quantitative experimental research is to gather evidence that allows a. threats to data validity are commonplace.Data visualization uses information displays such as tables and charts to help communicate key messages contained in the data.While statistical analysis is typically performed on quantitative data, there are numerous analytic procedures specifically designed for qualitative material including content, thematic, and ethnographic analysis.

Author Stephen Few described eight types of quantitative messages that users may attempt to understand or communicate from a set of data and the associated graphs used to help communicate the message.

No amount of statistical analysis, regardless of the level of the sophistication, will correct poorly defined objective outcome measurements.Specific variables regarding a population (e.g., age and income) may be specified and obtained.Geographic or geospatial: Comparison of a variable across a map or layout, such as the unemployment rate by state or the number of persons on the various floors of a building.Generalized linear model: An extension of the general linear model for discrete dependent variables.In a confirmatory analysis clear hypotheses about the data are tested.Users may have particular data points of interest within a data set, as opposed to general messaging outlined above.Quantitative methods emphasise on objective measurements and numerical analysis of data collected through polls, questionnaires or surveys.General linear model: A widely used model on which various methods are based (e.g. t test, ANOVA, ANCOVA, MANOVA ).The characteristics of the data sample can be assessed by looking at.

The integrity of data analysis can be compromised by the environment or context in which data was collected i.e., face-to face interviews vs. focused group.If one uses unconventional norms, it is crucial to clearly state this is being done, and to show how this new and possibly unaccepted method of analysis is being used, as well as how it differs from other more traditional methods.Descriptive and interpretive approaches to qualitative. quantitative and qualitative research traditions, data.

Log-transformation (if the distribution differs substantially from normal).There are a variety of cognitive biases that can adversely effect analysis.The chief aim of analysis is to distinguish between an event occurring as either reflecting a true effect versus a false one.

Also included are recommendations regarding how to manage specific course assignments.In his book Psychology of Intelligence Analysis, retired CIA analyst Richards Heuer wrote that analysts should clearly delineate their assumptions and chains of inference and specify the degree and source of the uncertainty involved in the conclusions.Basics of qualitative research: Grounded theory procedures and techniques.For example, plotting unemployment (X) and inflation (Y) for a sample of months.At times investigators may enhance the impression of a significant finding by determining how to present derived data (as opposed to data in its raw form), which portion of the data is shown, why, how and to whom (Shamoo, Resnik, 2003).Item response theory: Models for (mostly) assessing one latent variable from several binary measured variables (e.g. an exam).
