Data AnalysisTypes of Data Analysis
simplest form of quantitative (statistical) analysis
carried out with the description of a single variable in terms of the applicable unit of analysis
Univariate Analysis
basic way of presenting is to create a frequency distribution of the individual cases, which involves presenting the number of cases in the sample that fall into each category of values of the variable
can be done in a table format or with a bar chart or a similar form of graphical representation
Univariate Analysis
involves two variables, deals with causes or relationships
major purpose is to explain
one of the simplest forms of the quantitative (statistical) analysis
Bivariate Analysis
involves the analysis of two variables (often denoted as X, Y), for the purpose of determining the empirical relationship between them
In order to see if the variables are related to one another, it is common to measure how those two variables simultaneously change together.
Bivariate Analysis
based on the statistical principle of multivariate statistics, which involves observation and analysis of more than one statistical outcome variable at a time
Multivariate Analysis (MVA)
In design and analysis, the technique is used to perform trade studies across multiple dimensions while taking into account the effects of all variables on the responses of interest.
Multivariate Analysis (MVA)
Design for capability (also known as capability-based design)
Inverse design, where any variable can be treated as an independent variable
Analysis of Alternatives (AoA), the selection of concepts to fulfill a customer need
Uses for Multivariate Analysis
Analysis of concepts with respect to changing scenarios
Identification of critical design drivers and correlations across hierarchical levels.
Uses for Multivariate Analysis
Pusta, Peter Vernon P.
you can use a selection of criteria to analyze which variants have already reached or been set to a specific status, or for which objects the status is used
Status Data Analysis
aims at finding out not only how things are, but above all how they should be, which means that it will be necessary to define the subjective point of view that shall be used, in other words to select the people who shall evaluate the proposals which aim at improving the object of study
Normative Data Analysis
discipline of quantitatively describing the main features of a collection of data, or the quantitative description itself
Descriptive statistics are distinguished frominferential statistics (or inductive statistics), in that descriptive statistics aim to summarize a sample, rather than use the data to learn about the population that the sample of data is thought to represent
Descriptive Data Analysis
For example in a paper reporting on a study involving human subjects, there typically appears a table giving the overall sample size, sample sizes in important subgroups (e.g., for each treatment or exposure group), and demographic or clinical characteristics such as the average age, the proportion of subjects of each sex, and the proportion of subjects with related comorbidities
Descriptive Data Analysis
Pilapil, Wilson O.
a systematic determination of a subject's merit, worth and significance, using criteria governed by a set of standards
can assist an organization, program, project or any other intervention or initiative to assess any aim, realisable concept/proposal, or any alternative, to help in decision-making; or to ascertain the degree of achievement or value in regard to the aim and objectives and results of any such action that has been completed
Evaluation
enable reflection and assist in the identification of future change
often used to characterize and appraise subjects of interest in a wide range of human enterprises, including the arts, criminal justice, foundations, non-profit organizations, government, health care, and other human services
Primary Purpose of Evaluation
Classification refers to categorization, the process in which ideas and objects are recognized, differentiated, and understood
Classification Analysis
the item-by-item comparison of two or more comparable alternatives, processes, products, qualifications, sets of data, systems, or the like
In accounting, for example, changes in a financial statement's items over several accounting periods may be presented together to detect the emerging trends in the company's operations and results.
Comparative Analysis
Side by side examination of two or more alternatives, processes, products, qualifications, sets of data, systems, etc., to determine if they have enough common-ground, equivalence, or similarities to permit a meaningful comparative analysis
Comparative Analysis
For example, financial data of two firms from very different industries may be comparable if they use similar performance measures, follow similar accounting methods, policies, and procedures, and disclose their financial information to the similar extent. A very high degree of comparability may indicate uniformity.
Comparative Analysis
Presentation of Data
Perez, Kent Micky
arranges data in an ordered format, such as lowest to highest
can also use a stem and leaf plot for presentation
the researched data is presented to others in a paragraph form
could be hard for people to understand without a visual aid
Textual Presentation
data is presented in a chart or table format
statistics may be shown across several rows and columns, presenting data with certain parameters in a fashion that can be looked over and compared
Tabular Presentation
data is arranged in rows and columns by month or segment, which is used to show what particular day correlates to the day of the month or number unit of the monthly segment
calendar can be considered one of the simplest types of tabular data presentation
Tabular Presentation
Popa, Grace
visual display of data and statistical results
visual display of data and statistical results
basically summarizes how one quantity changes if another quantity that is related to it also changes
Graphical presentation
show and compare changes
show and compare relationships
bring facts to life
Purpose of Graphing
Attractive and Effective presentation of Data
Simple and Understandable Presentation of Data
Useful in Comparison
Useful for Interpretation
Remembrance for long period
Advantages of Graphs
Helpful in Predictions
Universal utility
Information as well as Entertainment
Helpful in Transmission of Information
No Need for training
Advantages of Graphs
Panaligan, Jesus Marcel H.
Types of Graphs
uses vertical or horizontal bars to represent numerical data.
bar graph compares amounts in a single time period.
Bar Graph
graph that uses pairs of bars to compare information
Double Bar Graph
A graph used to show changes over a period of time
Line Graph
graph that uses pairs of lines to compare information
Double Line Graph
circular graph that separates each category into a piece of the whole
Circular (Pie) Graph
