DATA 620 Data Management and Visualization Assignment - University of Maryland Global Campus, USA

Locate your very favorite multidimensional time series and tell us all about it.

Define your Time Series - A time series is a series of data benchmarked to a particular point in time; for example, the closing price of the stock of XYZ Corporation on December 1, 2, 3, 4, and 5 would comprise a time series of five data points.

Your time series should have the following characteristics:

1. It needs to span at least ten to twenty roughly equivalent time periods. A period may be a day, a week, a year, or some other unit of measure which makes sense for what you are measuring.

2. It needs to leave room for you to make a prediction for some time period in the future, based on the available data in your time series. For example, if you choose the years 1910, 1911, 1912, 1913, and 1914 to measure cigarette smoking behavior in Americans, your future prediction must be after this year, so you must now predict behavior for next year over a data gap which spans almost 100 years. A more sensible choice of years for this would be 1930, 1950, 1970, 1990, and 2010, which leaves you plenty of room to predict for 2030.

3. It needs to have at least three other variables for your data. These need to have occurred in the same time frames, but may be from different sources. In the example below, our main time series is the closing price of the stock, and the three additional variables were taken from other data sources.

Create your Story - Determine what the story in your data is. A good story has

A narrative, with a research question at the beginning, and a conclusion at the end. Examples of good narratives include, "Is the US crime rate really increasing?" or "What is happening to the crab population in Maryland?"

Each graphic will support some aspect of your story.

Each aspect of the story will be one brief caption or sentence. This will go on the top of your Story Point for your presentation.

A good test of your narrative is to see if you can give it to somebody who is not taking this class. Do they understand what you are claiming?

Key questions to consider as you craft your story:

Background of the data set - what motivated you to study this?

Description of the time series and trends you see.

Any interactions or explanations from background factors? For example, if you are doing CO2 emissions, can you include average global temperatures to support or debunk global warming?

Use annotations to elaborate on your story.

Write a One-paragraph Summary -

Write a one-paragraph (250 words or fewer) summary of your presentation.

It needs to be an Executive Summary: if a busy reader only reads the first sentence, s/he should know what your results are. Don't say "We analyze trends of Beanie Baby purchases." Say instead "Beanie Baby purchases are trending upwards sharply, and we forecast sales of XXX for next quarter."

The best summaries contain a hook. Why should the reader continue to read the paragraph? After reading the paragraph, why should the reader want to view your video?

Note - For the question, use data from the world bank data site to show the population growth in the following countries: Nigeria, China, USA, Russia and Australia. This should be done in Tableau.
