连续数据(Continuous Data): 1.连续数据是指可以在某个区间内取任意值的数据。 2.连续数据通常与测量或计量有关,可以是任何在一定范围内的实数值。 3.例如,身高、体重、温度等都可以被视为连续数据,因为它们可以在任何范围内取任意的数值。 离散数据(Discrete Data): 1.离散数据是指只能取有限个或可数个数值的...
如某销售部门客户服务质量的评估,0表示很不满意,1不太满意,2表示中性,3表示满意,4表示非常满意。 通过数据预处理中的数据规约,序数属性可以通过将数据的值域划分成有限个有序类别,将数值属性离散化而得到。应注意的是,标称、二元和序数属性都是定性的,只描述样本的特征,而不给出实际大小或数量。下面介绍提供样本定...
© Powerpointmaths All rights reserved. Discrete and Continuous Data Discrete data can only take on certain individual values. Continuous data can take on any value in a certain range. Example 2 Length of a film is a continuous variable. Example 1 Number of pages in a book is a discrete ...
Continuous Data can take any value (within a range)Examples:A person's height: could be any value (within the range of human heights), not just certain fixed heights, Time in a race: you could even measure it to fractions of a second, A dog's weight, The length of a leaf, Lots ...
continuous data为连续数据，discrete data为离散数据。把离散转化为连续，或者把连续转化为离散就可作相关。离散数据是在一个变量只能取某些固定值时产生的，连续数据是在一个变量可以在两个值间取任意值时产生。比如1、2、3这样的自然数就是离散数据，因为它是特定的自然数值，而比如[1,2]这个区间就...

Values that are assigned to the cells of a surface can be represented as either discrete or continuous data. Features and surfaces in ArcGIS can be represented as either discrete or continuous data. Discrete data, also known as categorical or discontinuous data, mainly represents objects in both ...
Discrete and Continuous Data As part of her fundraiser, Madison is selling cupcakes door-to-door in an effort to buy more flutes and trumpets for the school band. Instruments and cupcakes represent a form of quantitative data known as discrete data, which is data that cannot be divided; it ...
We call these continuous data and discrete data. Continuous data Continuous data is measured. Continuous data can take on any value as it’s measured. For example: Your weight. Your weight can be any weight within the range of human weights. Your weight is not a specific fixed number. ...
