Interval in statistics define
WebClass interval is a term that is used to denote the numerical width of a class in a frequency distribution. In a grouped frequency distribution, data is arranged in the form of a class. The difference between the upper-class limit and the lower limit gives the class interval. In statistics, there are two types of class intervals, namely ... WebWeight is measured on the ratio scale. Ratio: exactly the same as the interval scale except that the zero on the scale means: does not exist.For example, a weight of zero doesn’t exist; an age of zero doesn’t exist. On the other hand, temperature (with the exception of Kelvin) is not a ratio scale, because zero exists (i.e. zero on the Celsius scale is just the freezing …
