Frequently Asked Questions
What is this? What is Data Maven from Crunchzilla?
Data Maven is an interactive tutorial where you explore data and statistics.
So many people have tried to
learn about statistics, only to get bogged down in probability, theory, and math,
without feeling that they were able to do anything with it. Data Maven is
an intuitive game-like tutorial where you try answering questions with data and statistics.
The focus is on action. You answer questions, look at data, and discover how
to use statistics as your tool to do even more.
Why aren't you telling me all the details about statistics?
There are already a lot of tutorials and textbooks out
there that teach statistics with technical, in-depth
explanations of probability, sampling, confidence intervals,
distributions, hypothesis testing, regression, and so on. If
you want that, there are many choices available, many of which
are excellent supplements to Data Maven.
What is hard to find is a tutorial that is fun, immersive, and gets you immediately
working with lots of real data. Data Maven skips a lot of the explanation you
can get elsewhere and instead jumps straight into
what you can do with data and statistics.
By the time you finish Data Maven, you should be curious for
more. At the end, there is a list of other resources to go to to
learn more about statistics, data analysis, and data science.
Why doesn't this work perfectly on an iPad (or other mobile device)?
Data Maven will work and is playable on many mobile devices, but
it isn't designed for mobile. Why not?
Mostly because mobile screens are so small. It's hard to
read a lot on tiny mobile screens, even harder to see
detailed charts, and can even be a challenge to accurately
select the answer you want in the quizzes. Because of that,
Data Maven is designed to work on mobile, but not optimized
Data is plural, isn't it? Shouldn't you say "data are", not "data is"?
Data was originally the plural of datum. Years ago,
people did used to say "data are". Nowadays, the word datum is
rarely used, and the word data is treated as a mass noun similar
to the word information (e.g. "information is great and, golly
gee, data is too").
The Oxford English Dictionary states that data usually
takes a singular verb in current standard English. Most style
guides either favor "data is" or say either is acceptable. And,
"data are" sounds wrong to most younger people. So,
Data Maven from Crunchzilla uses "data is".
Where can I learn more about programming?
Code Maven is a fun way
programming, many of which are excellent supplements to Code Maven.
Data Maven from Crunchzilla is a combination of a game and tutorial
with a focus on action over explanation.
When you work through Data Maven, you dive right into playing

more. By the time you finish Data Maven, you'll find you too can use
data analysis and statistics to answer questions you have!
