Resist the Urge to Show Everything

Getting to the point where you have found data worthy of your dissertation takes an enormous amount of work. You test countless hypotheses that go nowhere, run analyses that get discarded, and look at the data from angles that prove dead ends. By the time you have something worth presenting, you've done ten times as much work as the findings show. And so the temptation arrives: show it all. Walk the committee through every test, every angle, every discarded model, as proof of how robust and thorough you've been.

Resist this urge.

Here's the distinction that makes it easier. Analysis has two phases with two different jobs. 

Exploratory analysis is what you do to understand your data: turning it over, testing everything, and figuring out what's actually noteworthy. 

Explanatory analysis is what you do when it's time to communicate: you have a specific thing to explain, a specific story to tell. The mistake isn't doing a hundred explorations. The mistake is presenting like you're still exploring when your audience came for an explanation.

Think of it like a museum and a dig site. The archaeologist moves tons of earth to find one artifact. The museum displays the artifact. Nobody walks through the exhibit wishing they could see the dirt, and nobody doubts the excavation happened. The finding on the pedestal implies the work.

When you show everything instead, you're presenting the data as it is rather than what your audience needs to know. In trying to prove your analysis robust, you hand the committee the job of deciding what matters, which is your job. Audiences notice when they're doing your work, and it costs you the credibility you were trying to demonstrate.

But here's the part that should loosen its grip: the work you cut doesn't disappear. The discarded analyses live in your appendices and your methods chapter, where thoroughness belongs. And most importantly, they live in you. When a committee member asks "did you consider X?", you get to say "Yes, and here's why it didn't hold." Every dead end you don't present becomes an answer you have ready. The defense Q&A is where all that invisible work pays off, and it pays off far better as a confident answer than as slide forty-three.

So when presenting your findings, concentrate on what your audience needs to know. What is the specific story you want to tell? What is the specific thing you need to explain? Everything that serves those questions stays. Everything else waits for the Q&A.

Data in Plain English helps you sort your findings into the exhibit and the archive, so what you present is the best version of your data, and what you cut still has your back. You did all the work. Show them the artifacts, not the dirt.
