The story of Cortana, Microsoft's Siri killer. By Tom Warren on April 2, 2014 02:00 pm 570Comments.

Discrete and continuous data. Raw data is the information we get when we do a survey. For example, we might have a list of heights or shoe sizes. Data can either be discrete or continuous. Discrete data. This data set shows a group of discrete data. This is called discrete data because the units of measurement (for example, CDs) cannot be split up; there is nothing between 1 CD and 2 CDs. Bitesize CD store 31 January 2008
Word categories are not the only type of variable that is discrete; numbers can also be discrete. For example, at the beginning of this section, we mentioned that you could use a bar chart to plot the number of families with 0, 1, 2 or more children.Here, the number of children in a family is a discrete variable.So too are the number of goals scored per match by a football team, and the number of bedrooms in a house. Bar charts are normally drawn with separate bars in order to emphasise the discrete nature of the data.Discrete variables often relate to counted items.o too are the number of goals scored per match by a football team, and the number of bedrooms in a house.
