Did you calculate a measure of uncertainty for each estimate on the scientific scale?
Did you immediately split your data into training and validation? Did you use cross validation, resampling, or bootstrapping only on the training data? Did you create features using only the training data?
Did you estimate parameters only on the training data? Did you fix all features, parameters, and models before applying to the validation data? Did you apply only one final model to the validation data and report the error rate?
Did you identify potential reasons that causality may not be appropriate such as confounders, missing data, non-ignorable dropout, or unblinded experiments? If not, did you avoid using language that would imply cause and effect?
Did you describe the data set, experimental design, and question you are answering? Did you specify the type of data analytic question you are answering?
Did you specify in clear notation the exact model you are fitting? Did you explain on the scale of interest what each estimate and measure of uncertainty means?
Did you report a measure of uncertainty for each estimate on the scientific scale? IX Figures Does each figure communicate an important piece of information or address a question of interest?
The Elements of Data Analytic Style
Do all your figures include plain language axis labels? Is the font size large enough to read? Does every figure have a detailed caption that explains all axes, legends, and trends in the figure?

Did you try to have someone else run your analysis code to confirm they got the same answers? download it on Leanpub or site! First this happened:. And apparently not just for me: So lesson learned, there is no soft open with Coursera.
Here is the post I was going to write though:. I have been doing data analysis for something like 10 years now gulp! One of the things we do in my data analysis class at Hopkins is to perform a complete data analysis from raw data to written report every couple of weeks.
One goal is to summarize in a succinct way the most common difficulties encountered by practicing data analysts. It is modeled loosely in format and aim on the Elements of Style by William Strunk.
But just as with writing, new analysts would do better to follow the rules until they know them well enough to violate them. The book includes a basic checklist that may be useful as a guide for beginning data analysts or as a rubric for evaluating data analyses.
This checklist provides a condensed look at the information in this book.We allowed participants to update their expectations and confidence levels for a given forecast question as often as they wished, up until the point the question was resolved and a ground-truth answer was available. Here are a few widely publicized examples of machine learning applications you may be familiar with: The heavily hyped, self-driving Google car?
Bundesgesetze nach Absatz 1. Did you consider whether the question could be answered with the available data?
When we say affordable, we mean it.
This interface provided alerts for new questionnaires for them to complete, new forecasting questions for them to answer, and optional research studies that they might participate in.
