How Reliable is Big Data?
The era of Big Data is underway. Compared to Small Data, machine learning, computerized databases and other modern technologies makes it possible for Big Data to do handle massive data and reveal information in a way that individual bits of data can't. Random sampling's accuracy depends on ensuring randomness when collecting data from samples. Analyzing only a limited number of data points means errors may get amplified, which may reduce the accuracy of the overall results potentially. Meanwhile, Big Data gathers and analyzes massive data to produce some excellent results that we could never know when we are limited to smaller quantities, like address various societal ills, offer potential of new insights into diverse fields. But as the data comes from an environment of uncertainty and rapid change, bigger data may not a better data. Increasing the volume of data may lead to inaccuracy, but in return for relaxing the standards of allowable errors, which produces more valuable information and better results.
big data is gaining popularity in business organizations. How would the concept of big data alter the perspective of what type of data is stored and the challenges it poses? Consider the various sources outlined in the chapter for gathering data.
What is big data? How can big data analytics help a company grow? Explain Hadoop and MapReduce. Can an ERP play a part in this growth?
Cognitive Technology and convergence of big data, digital marketing and consumers. Explain how big data can provide insight to cognitive computing. Be sure to use examples where appropriate.
"How accurate and reliable is your data (how good are you at pipetting and timing)? You basically repeated one of the reactions 3 times. How close are the rates?" I understand you might not be able to answer this question without my data but can you walk me through how to answer this?

a) Are data on GDP per capita reliable in measuring the welfare of citizens in a country? b) How useful are experimental data, such as that collected from games such as the Ultimatum game, in understanding the behaviour and preferences of people in an economy? (7 marks)
With regard to big data, the term "velocity" refers to: A. How current the data is that is being acquired (i.e., is it being acquired at the time it is happening, or close to it) B. The speed at which the data is being transmitted across the network (e.g., in Mb per second) C. The speed at which the events that are being monitored are happening
