Are results weighted?
Yes. By default, all statistics use the sample weight provided for each selected sample. If a sample has no weight, its results are unweighted.

Online Data Analysis FAQs
Short answers to common questions about using the Online Data Analysis (ODA). Use the index on the right to jump to a question.
Can I export the results?
Yes. You can export tables and charts to Excel (.xlsx), PDF, or download a PNG snapshot.
Can I change the selection of samples while viewing results?
Yes. Use the Selected samples control shown beneath the results to open the selector and add or remove countries/regions.
Tip: Select only the countries you really want to compare — very large tables can be slower to generate and harder to read.
Is the ODA free?
Yes. You can produce and export your own figures and tables. Please cite Latinobarómetro as recommended in the Data & Documentation section.
What do the percentages mean?
Percentages are calculated over the (weighted) number of valid responses for the selected category. “Don’t know/No answer” can be excluded when running a cross-tabulation.
By default you will see percentages over column totals, but you can switch to row totals, sample totals, or show absolute values.
Why don’t the percentages add up to 100%?
Rounding, multi-response items, or excluded missing values can lead to totals slightly above or below 100%. When weights are applied, totals may also vary slightly.
How are missing values handled?
By default, “Don’t know/No answer/Refused” are included in calculations. You can exclude them by clicking the MV button above the chart.
Can I compare results across time (waves)?
Yes. Two ways: use the Round buttons to see results in different waves where the same question was asked, or switch to the Time Series view using the top button.
Are variables fully comparable across countries and waves?
Not always. Some items may not be fielded in every wave. You can see where a variable was asked by checking the Round buttons (Wave 1, Wave 2, Wave 3, …) shown above the chart options.
Does ODA provide significance tests?
ODA reports descriptive statistics. For inference (e.g., tests or models), export your results and use statistical software.
What is the base (N) for a table?
The base is the weighted count of valid cases after applying filters and sample selection. The Ns displayed refer to this base.
Why is my table slow to load?
Very large selections (many countries/waves or many categories) take longer to compute. Reduce the number of samples or collapse categories to speed up rendering.
Which browsers are supported?
Recent versions of major browsers are recommended. For large tables, a desktop browser provides the best experience.
How should I cite results from ODA?
Please use the citation format provided for the study you are using. See Study level downloads.
