Veracity — A data scientist must be p… 13 Challenges For Big Data In Education by Sara Briggs , opencolleges.edu.au “The problem with learning data, historically, is that we’ve always gone for the low-hanging fruit,” says Elliott Masie for the American Society for Training and Development. This is often described in analytics as junk in equals junk out. The grand challenge in data-intensive research and analysis in higher education is to find the means to extract knowledge from the extremely rich data sets being generated today and to distill this into usable information for students, instructors, and the public. Data Challenges The data challenges associated with big data can be pointed down as: Variety: Uniting multiple sets of data in which the real challenge is to handle the multiplicity of types, formats, and sources. Data is a powerful tool for any modern business, but as we’ve discussed in the previous two blogs, managing data is no easy task. These include data quality, storage, lack of data science professionals, validating data, and accumulating data from different sources. Laney first noted more than a decade ago that big data poses such a problem for the enterprise because it introduces hard-to-manage volume, velocity and variety.

Following are some of the Big Data examples- The New York Stock Exchange generates about one terabyte of new trade data per day. 3.2 The challenges of data quality. Shortage of Skilled People. As a result, many big data initiatives remain constrained by the skills of the people available to work on them. In terms of the three V’s of Big Data, the volume and variety aspects of Big Data receive the most attention--not velocity. Now look at big data spending today – according to recent numbers from Gartner, spending on services outweighs spending on software by a ratio of nine to one*. Known as the three Vs, these are volume, velocity, and variety, often complemented with variability and value. The statistic shows that 500+terabytes of new data get ingested into the databases of social media site Facebook, every day.This data is mainly generated in terms of photo and video uploads, message exchanges, putting comments … In the final chapter of this three-part blog series, we look at three more leading data management challenges.
