Mercury is the only common metal which is liquid at ordinary temperatures. Mercury is sometimes called quicksilver. It is a heavy, silvery-white liquid metal. It is a rather poor conductor of heat if compared with other metals but it is a fair conductor of electricity. It alloys easily with many metals, such as gold, silver, and tin. These alloys are called amalgams.
describe big data, so that you can speak intelligently about it when asked. So probably the main thing to recognize is this notion of the three V's of big data, which are volume, velocity and variety.
Discrete vs Continuous Data. Data is the most salient entity in statistics as it is necessarily the âstudy of the collection, organization, analysis, and interpretation of dataâ. The numerical data used in statistics fall in to two main categories. They are discrete data and continuous data. What is discrete data? If the numerical data can take only an at most countable number of values, then such data is called discrete data. An at most countable number is either finite or countable. An example will illustrate this further.
