    An example of this is how Vietnamese names may be stored differently in a US database and a Vietnamese database. A Vietnamese name can be three or four words long. A first name can comprise two separate words. However, many US online forms, which reflect their databases, limit first and last names to one word. This leads to potential mismatch…[Read more]

    I really like this Gender Wage Gap graphic for its simplicity, comprehensiveness and ease of use. The graph tells the story of wage inequality with only 5 colors and through simple flat lines. It makes the career categories bold, so as to save the space usually consumed by clutter-prone hierarchies. The interactive elements (pop-up information,…[Read more]

    This is my example for such a situation: I have a table for political data (political systems, current ruling party, etc.) in each country of the world. I have another table for each country’s economic metrics (GDP, GDI, debt, etc…). By using the join on these tables and applying necessary WHERE BY functions, I can figure out the GDP growth of…[Read more]

    I think the trickiest part about creating an ERD from a problem description is to avoid overthinking the situation, which may lead to listing entities irrelevant to the problem description or giving entities attributes they don’t have. This is because the way I approached ERDs back in MIS2101 was an open, unstructured one; I just came up with as…[Read more]

    When competing in the Alexion Analytics Challenge last semester, my teammates and I collected diabetes statistics (raw data) and nutrition intake (raw data) for countries and unique territories. These data on their own did not help us gain any insights into the global diabetes situation. By sorting the diabetes prevalence rate and calculating the…[Read more]

    I use Facebook almost everyday.
    A row will be an individual post.
    Some of the columns would be:

    – Number of shares.
    – Type of post (pictures, textual statuses, videos, or shares)
    – Number of words in the post.
    – …

    I have worked with Excel before, but I have not used it for any data-intensive operations or tasks that require complex functions. Therefore, I have not fallen into the traps in the list yet. However, I have made mistakes that have element of number 2 and number 3.

    I used to work for a non-profit organization. I interacted a lot with data…[Read more]

    I believe that among the eight core principles mentioned by Stephen Few, “Simplify” is the most important one because it allows visualized data to be noticed and digested in an age where data are so plentiful that we spend less time on each set of data. Social media platforms provide good examples. On many occasions, we scroll quickly through our…[Read more]

    For me, the most essential takeaway from Mr. Whetstone’s talk is how one approaches data is sometimes more important than the data one can collect. One great example is QVC’s effort to standardize data sets and metadata so that it is easily understood by all of its analysts across the world. Another memorable example is Mr. Whetsone’ story about…[Read more]

    The reason this article caught my eye in the first place is that I am currently worried about how a popular Facebook page in my country is posting random nutrition facts gathered from dubious sources all over the Internet. This page has more than a million likes,…[Read more]

    A piece of conventional wisdom that I am familiar with is “Reading books regularly makes one more knowledgeable and intelligent”. One way to test whether this statement is true or not is to conduct a survey. Firstly, randomly selected participants will provide the average number of books they read per year. All surveyed participants will then take…[Read more]
