Statistical Data Presentation
Analysis of data
Presentation of the Research Report
Basically there are two contexts in which the results of research can be presented: academic context and non-academic context. In both contexts, a research report is presented, but its format, nature and length are different.
The types or methods of analysis are varied and will be discussed below, each method has its rationale and a specific purpose, no more analysis than necessary should be done.
The main analyzes that can be carried out are:
Descriptive statistics for the variables, taken individually.
•
“Z” Scores.
• Ratios and rates.
• Inferential statistics calculations and reasoning.
• Parametric tests.
Non-parametric tests.
• Multivariate analysis.
Measures of central tendency are those that indicate the center of a
data set.
They are identified as:
Mean or Average
Median and Mode
Range, Variance and Standard Deviation
The Coefficient of Variation
Sometimes only the published report is delivered and explained verbally (such is the case of theses), but on other occasions the delivery of the report is accompanied by a presentation with various supports such as acetates, graphics, audiovisuals, videos, computerized systems. video, power point presentations and other resources that researchers can use
Academic context implies that the results will have to be presented to a group of professors-researchers, students of a higher education institution, readers with high educational levels, members of a research agency and individuals with a similar profile.
Non-academic context implies that the results must be for commercial purposes or to the general public (for example, readers of a newspaper or magazines), to a group of executives with little time to dedicate to a subject or to people with less research knowledge.
