Tableau Training in Dundee
Tableau training for Dundee teams, built around aggregation — the concept that decides whether a dashboard is right. Everything shown is computed at some level of detail, and a percentage that is correct per region and wrong for the whole country is almost always somebody averaging an average without realising it.
Why this comes up
The problem
The regional figures are right, the national total is not, and nobody can explain the difference.
What you get
What we deliver
- Aggregation taught explicitly, including what a view is calculating and at what level
- Level of detail expressions covered, since they solve the problems filters cannot
- Published data sources used so definitions are shared rather than rebuilt per workbook
- Extracts and live connections compared, with the performance consequences of each
- Dashboard design taught for comprehension rather than density
- Publishing and permission conventions agreed before workbooks proliferate

Tableau Training in Dundee — common questions
- Why is aggregation the central concept?
- Because it silently determines the answer. A ratio calculated per row and then averaged gives a different number from the same ratio calculated on totals, and both look plausible on a chart — so understanding which one a view is producing is the difference between reporting and guessing.
- What do level of detail expressions solve?
- Questions that mix granularity. Comparing a customer's spend against the average for their segment requires two levels of detail in one view, and without these expressions people resort to blending data or exporting to a spreadsheet, which reintroduces every problem the tool was bought to remove.
- Should we use extracts or live connections?
- Extracts for speed and predictability, live where the data genuinely changes minute to minute. Most organisations choose live because it sounds better and then complain about performance, when a scheduled extract would have served the actual reporting need perfectly.
- Why publish data sources centrally?
- Because it stops every analyst inventing their own definition. A certified published source means revenue is calculated once, and the arguments in meetings become about what the numbers mean rather than about which workbook is correct — which is the real return on a training programme like this.
- Do you work with businesses across Dundee City?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Scotland, including Dundee and the surrounding Dundee City area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Dundee businesses do you usually work with?
- Interactive and games-adjacent development, plus life sciences data systems tied to the university research base. Beyond that we work across Games & Digital, Life Sciences, Higher Education, Healthcare and Marine.
- Do you cover the areas around Dundee?
- Yes — we work throughout Scotland, including Perth, Aberdeen, Edinburgh. Dundee is an urban area of roughly 150,000+, and we take on work across the wider Dundee City region rather than the city boundary alone.
