Data In Action

Data in Action

    Data is information. Data is represented everywhere from the numbers on your social security card to your student id, your gym locker combination, and much, much more! Lots of data is collected in surveys.

    Many  governmental and commercial organizations have large databases containing information collected from national, regional, and local surveys. This data reflects people’s interests, opinions, and lifestyles. For example, the U.S. Census Bureau is the country’s longest running and largest database. The U.S. Census Bureau has developed standardized definitions, surveys, and sampling techniques to gather data. Data is gathered for very large databases. Within corporations and the government, specialized departments employ many people to track and analyze trends in agriculture, health, lifestyle, medicine, labor, business, consumer spending, economy, education, and many other subjects. This is a career for you to consider.

      Sometimes data is collected through surveys and opinion polls.  A.C. Nielsen, George Gallup, Elmo Roper, and Louis Harris are examples of these opinion polls. Major political candidates, campaigns, newspapers, television stations, and other news organizations regularly conduct their own surveys and report their results. School districts, universities, and colleges also keep large databases of information. Subject directories are created to search databases organized by subject matter starting with general subject-headings, then move to specific subheadings.

      Since many databases are created using public tax money, their research and findings are available to the public. Looking at data collected from other organizations is called secondary analysis. Secondary analysis accesses and often reuses data gathered by someone else, often for other purposes. Data Mining is the practice of examining large databases in order to generate new information.

    Results of surveys can often be divided into segments or markets on the basis of geography, demographics, and other attributes. Agencies can provide listings of data sets and publications which can be used for secondary analysis. They are also able to answer additional and clarifying questions.

    With the growing sophistication of the internet it is simple and efficient to access and analyze data from large database for a variety of purposes. Online queries of databases and online searches are a fast way to search for research and other information on specific topics. Business Analyst Oscar Gusman describes computer CPUs and databases as primitive replications of our own brain.

Weekend Ed. Quote~January 25

“I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the sea-shore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.” ~Sir Isaac Newton, birthday 1-4-1643

Weekend Ed. Quote~January 18~Reading and the Brain

“The changes were registered in the left temporal cortex, an area of the brain associated with receptivity for language, as well as the the primary sensory motor region of the brain. Neurons of this region have been associated with tricking the mind into thinking it is doing something it is not, a phenomenon known as grounded cognition – for example, just thinking about running, can activate the neurons associated with the physical act of running.” ~Tomas Jivanda writing in this article from The Guardian.

crossing the Rubicon

“Take we the course which the signs of the gods and the false dealing of our foes point out. The die is cast” ~Julius Caesar, on the crossing of the Rubicon, January 10, 49BC

According to Garrison Keillor in The Writer’s Almanac, “With Caesar’s crossing of the Rubicon, the Roman Republic was thrown into civil war. Eventually, Caesar defeated Pompey and his allies and emerged as the winner. As emperor, he made some radical changes in government. He decreased the power of the provinces, and centralized power in Rome. He eliminated much of the government’s debt, disbanded powerful guilds, and rewarded people for having children in an effort to increase Rome’s population. He set a term limit on governors, launched a huge rebuilding effort, established a police force, and modified the calendar. He made himself incredibly powerful and demanded that everyone revere him as part-deity. Because of Caesar, the phrase “crossing the Rubicon” has entered popular culture, meaning ‘past the point of no return.'”

A Poem for the First Monday of the Year

A Poem  for the First Monday of the Year, perhaps for students to listen to at some point today:

Mindful
by Mary Oliver

Everyday
I see or hear
something
that more or less

kills me
with delight,
that leaves me
like a needle

in the haystack
of light.
It was what I was born for —
to look, to listen,

to lose myself
inside this soft world —
to instruct myself
over and over

in joy,
and acclamation.
Nor am I talking
about the exceptional,

the fearful, the dreadful,
the very extravagant —
but of the ordinary,
the common, the very drab,

the daily presentations.
Oh, good scholar,
I say to myself,
how can you help

but grow wise
with such teachings
as these —
the untrimmable light

of the world,
the ocean’s shine,
the prayers that are made
out of grass?
