Designing a questionnaire: how to convert the content of a survey into digital form

When two dimensions are not enough: the multidimensional scatterplot in ps imago pro

A scatterplot, or scatter graph, is a popular diagnostic tool for associations between quantitative variables. It is invaluable in correlation analysis for readily assessing the nature and the shape of the relationship between two variables.

Consumer shopping value analysis using regression trees. Part 2

Regression trees are a very interesting data analysis technique commonly used in tasks related to poststratification, forecasting, and segmentation.

Multidimensional scaling in brand positioning

Positioning a product in the context of the competition, or the identification of a product’s features and attributes are often key issues facing marketing, promotion, and product managers.

Automatic linear modeling: ensemble models

Today, we will look into ensemble model methods.

Car value: variable selection for linear modelling

The Automatic linear modeling procedure is intended to streamline the work of analysts who use regression models.

Data sourcing: pros and cons of desk research

What is data? What is data needed for? Can data be divided according to specific criteria ? Does data only come from surveys?

Consumer shopping value analysis using regression trees. Part 1

How can we estimate the potential value of consumer shopping, predict the behavior of a visitor to our website, or reduce the risk of credit losses?

How to boost a decision tree algorithm

The decision tree is a popular and effective algorithm used primarily in classification work, but it also serves well in predicting quantitative phenomena. The charm of methods based on decision trees comes mainly from the fact that they present us with a set of convenient decision, or business rul…

Basics of a questionnaire survey with PS QUAESTIO PRO

The goal of computer software is to support the user at work. The PS QUAESTIO PRO platform is no different.

Shopping for a mountain trip: analysis of multiple response sets

Multiple response sets often form the basis for further detailed questions about opinions on selected products.

SNA or network as an analytical object

Today, we will look into Social Network Analysis (SNA), or Social Relation Analysis.

When is a value ‘good’ or ‘bad’? About thresholds and alerts in dashboards

The dashboard is a form of reporting, which allows the analyst to convey information in a concise way.

Tables for multiple questions measured using the same scale

Surveys often use questions where respondents assess different elements on the same scale.

Sankey diagram

When analysing data on migration, transport, international trade, or traffic on a website, you are often faced with the problem of visualising the flow between the analysed units.

Word cloud: an extraordinary visualisation from an ordinary table

Frequency, group structure, or percentage share analysis is one of the first tasks of an analyst.

Hierarchical graph

Hierarchical data can be presented using various visualisations. Today’s article will focus on the hierarchical graph.

Correspondence analysis: calculating distances in a table

Correspondence analysis is one of the most convenient and popular exploratory techniques in data analysis.

Caring for the brand: repositioning, campaign optimization and new product recommendations

50 years of SPSS – statistical data analysis software

It all began in 1968, when Norman H. Nie, C. Hadlai (Tex) Hull and Dale H. Bent decided to develop software based on the idea of using statistics to transform raw data into information necessary for decision-making. At that time, not even wealthy Stanford University housing those young science enth…

Pointing the way with arrows

When creating dashboards, reports, or infographics, you often use other elements besides charts and tables. Individual numerical values are often presented as text (with a suitable style that attracts the readers attention and matches the whole report visually), sometimes with meaningful icons. Suc…

Visualising decision trees: the classic refurbished

In this post, we continue to discuss the visualisation of nested hierarchical data. In my previous blog, I showed how hierarchical data can be presented in a two-dimensional space as a treemap. This approach, however, has some limitations, namely the number of nesting levels. The treemap can handle…

Maps that grow out of trees: data visualisation as an artform

In the previous PS blog “Trees that grow out of tables”, Janusz Wachnicki described how a good understanding of the humble crosstab can help us utilise classification trees more effectively. When it comes to visualisation, can classification results be presented any other way than in a tree? The an…

Series plot

The series plot is a type o linear or layered plot most often used to represent changes in time. The plot may represent size for a primary variable category or statistics for a selected quantitative variable. Individual points of the plot representing data are connected with a line from the first v…

Building charts with bricks

Data visualisation helps present in an attractive way information that could be difficult to interpret in the form of a table. Undoubtedly, for many managers, the phrase ‘time is money’ is a life motto, not a cliché. They receive a lot of information in tables but often need to quickly verify the p…

Table or cube? Reporting in the form of olap cubes

When we want to include a lot of values in a table, in several various cross-sections e.g. by time, region, type of phenomenon, we have several approaches to choose from.

Violin plot

Before starting a more complex data analysis, it is worth taking a closer look at variable distributions which are of interest to us.

Correspondence analysis: solution quality assessment

Correspondence analysis is a technique often thought of as an alternative to a crosstab (contingency table).

Basic steps when design tables

Humans presented data in tabular format already in the ancient times. Thus, sometimes we can be deluded that structuring and reading tables is intuitive and does not require expert knowledge

Perceptual maps: choosing the correct normalization method

In this article you can find perceptual maps prepared using different normalization methods.

Dartboards and dashboards

The dartboard visualization is another useful medium for presenting the results of analyses on a dashboard.

Speedometers in reporting

Speedometers, or gauges, are very intuitive hence their popularity in dashboarding. But they evoke mixed feelings among analysts.

Deciding to remove an item from the scale

Sometimes instead of asking a single question in a survey, we ask a whole set of questions, which are intended to be used later to build a scale.
