- 16. A few examples…
- 20. Intermission A brief return to high school science class
- 21. Numerical vs. Categorical variables • Numerical • Categorical
- 22. Independent vs. Dependent variables • Independent • A variable that changes in a tightly- controlled or predictable manner • A variable used to try to cause and/or observe a change in dependent variable(s) • Dependent • A variable whose value changes (or seems likely to change) as a function of the independent variable https://www.dreamhost.com/blog/wp-content/uploads/2008/04/plants.jpg http://www.cals.ncsu.edu/agcomm/news-center/media-releases/in-plants-small-changes-make-big-impact/
- 23. Dimensions vs. Measures • Dimension • Independent variable • Variable defining the scale/axis to slice up some other variable against • Can be numerical or categorical • Tableau automatically treats any categorical variable as a dimension • Measure • Dependent variable • Almost always numeric • Holds the data you expect to change as a function of your independent variable
- 24. Continuous vs. Discrete A distinction that almost always applies to numeric variables being used as dimensions • Continuous • Discrete
- 25. Columns, Rows, and Marks • For most types bar/line charts, you have to have at least one variable in the “Column” bar and at least one variable in the “Row” bar. • Specifying a “Mark” variable causes whatever graph is already on your screen to be sliced up by that variable – so you can investigate how differences in one metric (ie age, income etc.) influence changes in another.
- 26. Options, carets, and context menus, oh my! • There are hundreds of them • Do not be afraid of them • Do not worry about knowing what all of them do • DO explore them • And when something weird happens…
- 27. Undo is your friend • If When anything strange happens… ?
- 28. Tableau ≠ Excel • Tableau concepts are both somewhat unique and somewhat portable • Microsoft Power Query and Power Pivot offer many of the same features – though you’ll have to put in more effort to make them work the way you want
- 29. Tableau Key Concepts • Numerical vs. Categorical • Dimensions vs. Measures • Discrete vs. Continuous • Rows, Columns, and Marks • There are lots of options • “Undo” is your friend • Tableau ≠ Excel* *except when it does

Editor's Notes
- TechSoup Global doesn’t just help NGOs overcome barriers to effective use of technology. We also help NGOs overcome language, economic, geographic, cultural, knowledge, and access barriers. We create new ways to access technology, new paths to connect and network, and new means to learn and develop skills — all so that NGOs can operate at their full potential, more effectively deliver their programs and services, and better achieve their missions.

- Basic introduction to how to start using Tableau, and to the power that it gives you NOT a comprehensive overview – that could span several full graduate-level courses Don’t worry about remembering everything; there are tons of resources available on-line – and we’re here to help
- Here’s a roadmap of what we’re going to be covering today There’s some terminology here that will need some explaining – don’t worry; we’ll get to that in a minute First, let’s actually step through this process
- Let’s start out by taking a quick look at where we want to end up Click for a few static pictures
- DO NOT ADVANCE TO NEXT SLIDE. Break here, and go into demo
- Because digging into data really is science, at the end of the day
- Mythbusters actually found evidence for the plant-talking hypothesis, at least somewhat
- Independent variable Classic plants experiment: pet the plant, sing to the plant. In that case, your dimension/IV is sunlight yes/no. Your dependent variable
- If a dimension is being treated as continuous, Tableau will assume that all the data being shown should “flow together,” and any gaps in the dimension variable’s dataset should be visually hidden by best-guess connecting lines. If a dimensions is being treated as discrete, Tableau will show each distinct value of the dimension variable as an isolated entity, and will not make any guesses about missing data. Roughly speaking, these terms refer to the difference between line graphs and bar graphs
- As strange as it sounds, it is completely valid – and often very useful –for a Column/Row arrangement to include different “slices” of a single variable: one slice that treats the variable as a dimension, and another slice that treats the variable as a measure.
