Homework answers / question archive / Week 3: Business Intelligence vs Data Analytics Group 2 is on initial post/discussion leader duty this week
Group 2 is on initial post/discussion leader duty this week. Groups 1 and 3 are on reply duty.
Welcome to the first discussion of the course. We're only in Week 3 and other than the fact that the title of the course contains both Business Intelligence AND Data Analytics and the fact that the course is divided into different Modules, one on Business Intelligence and another on Data Analytics, they seem like separate things, right?
Well that's what this first discussion is going to find out.
First of all, as a way of introducing data visualization several weeks before we even cover it in class, I'd like everyone (ALL students, not just the initial post group) to get acquainted with Google's Ngram Viewer: https://books.google.com/ngrams.
Basically the Ngram Viewer allows you to see a graph of the occurrence of a given word or phrase over a specified period of years in the entire corpus of books contained in the Google Books collection. You can also enter several words or phrases to compare the evolution of usage over time. The default (sample) ngram on the day I visited was a comparison of
Albert Einstein,Sherlock Holmes,Frankenstein
which resulted in
Your tasks and the discussion topic(s) this week:
1. ALL students should use Ngram and try various combinations of
You might try allied terms like
Be sure to change the years, you'll definitely want to include through to the current year and I think you'll quickly find that years before 1900 (sometimes later) don't show much. Think about what the graph is showing you in terms of the usage of these various terms. Be aware that even if you enter the current year, Ngram may change that year depending on the data available (currently, it seems to 'default' to 2008 as the most recent year available).
2. INITIAL POST GROUP: in addition to the Ngram exercise, members of the initial post group should also conduct a web search for definitions of at least business intelligence and data analytics. I'm sure you'll find more than a few sites willing to compare the two. The topic this week:
Compare and contrast the terms business intelligence and data analytics. That is, how are they similar, how are they different?
You should include in your initial post a brief discussion of the Ngram findings AND a brief discussion of your search for definitions.
3. REPLY GROUP: in addition to the Ngram exercise, members of the reply group should also conduct a web search for definitions. Your role is build on an initial post with additional insights/information that will further the discussion.
You may want to include a 'snip' image, in particular of any Ngram that you create. Information about creating a 'snip' of an image from your screen is given below in Additional Info. NOTE: LEO does not allow you to directly cut and paste an image into a discussion. You will need to save the file as an image and then click on the small camera icon to insert the image. Tedious, but a good skill to learn.
Additional info:
If you want to delve deeper into Ngram (not required), you may have a look at wildcards and other advanced options.
If you're not sure how to 'snip' an image from your screen or browser, here's a tutorial from Microsoft and another from Apple. Please take care to take snip only of the image you want to share, NOT your entire screen.
