Applications of Big Data

Instructor: Kaitlin Oglesby
Big data is now a big word that more and more people seem to be aware of. But what are its applications? In this lesson, we see how big data can be used in healthcare, education, and business.

Different Applications

Chances are you've been hearing a great deal about how big data is going to change the world. After all, information is power, and we've seen it happen before. The internet changed how people interacted and did business, and that was with just gaining access to other information that people already knew. With big data, suddenly we'll be able to manipulate truly massive amounts of data in ways that we never thought possible. From those manipulations and observations, we'll be able to find truly revolutionary ways of doing things that we simply never thought of trying before. In this lesson, we're going to look at the potential applications of big data in healthcare, education, and business.


If you are like millions of Americans, chances are you have some sort of wearable technology that monitors your heart rate, oxygen levels, pulse, and activity levels. In an instant, that may only serve to help make sure that you are getting a workout. But because all of this data has been created, it can be aggregated with your data from previous weeks and months, helping doctors get a good picture of what state of health you are in. This establishment of a baseline helps them detect irregularities much faster.

Healthcare won't only be revolutionized by big data when it comes to prevention. Big data will also let pharmacists better gauge proper dosages for a specific person by drawing on many more data points that just age or weight. As such, medication becomes more effective with fewer side effects.


Speaking of using big data to seek out opportunities to help an individual, imagine if big data was applied to the classroom. In some schools, student activity levels are monitored so that facial expressions changing could be a cue that the student has either lost interest or is confused. That allows the teacher to pinpoint the exact location of the lesson that should be revisited.

Of course, it's not just futuristic classrooms that are seeing the advantages of big data. Education has seen wide improvements since the development of big data. Apps designed to help teach languages are using big data to vary their approach, allowing them to find instructional techniques that work well for a given student given past successes.
