Perceptual maps: choosing the correct normalization method

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

Cross-selling and tables

What combination of products frequently end up in a shopper's basket? What services are usually bought together by consumers?

Weights and tables

When creating a table, you can present weighted or unweighted data. As usual, the answer depends on the situation. You will get my meaning in a minute, but first, let me explain briefly what weighting adjustment is.

Is gambling addictive? What if the respondent has no opinion?

The standard approach to investigating a single categorical variable involves a few elements.

Dartboards and dashboards

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

How to prepare for reliability analysis?

The area of reliability analysis is of interest first of all to those who plan to use scales and indices in their studies, namely more complex indicators than a single survey question.

Three ways to perceive reliability

When measuring a phenomenon, you need to select the right tool. To measure temperature, you use a thermometer; alcohol content in breath is measured with an alcometer; and weight, with bathroom scales. In survey research, the measuring tool is the questionnaire and its questions. To measure the age…

Correspondence analysis: solution quality assessment

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

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.

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

When letters count in a table

A common task analysts are often faced with is to establish whether there are any relationships between variables and, if there is a, what is the nature of the relationship.

Reduction of multidimensionality

Is a simple two-dimensional coordinate system always enough for us?

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…

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.

Crosstabs as charts: introducing the contingency map

Tabular presentation is one of the most universal reporting techniques.

Welcome to the world of optimal scaling, I.E. The conversion of a qualitative variable into a quantitative one

From crosstab to correspondence analysis: how exactly are the rows and columns of a crosstab transformed into coordinates used in a chart?
