range

It is defined as it contains all data and it is also length of the smallest intervals. It is based on two observations that are poor and weak and it is calculated by subtracting the lowest to the highest sample which includes statistical dispersion. Range, is the simplest method of measuring the variability and it is used only for highest score minus the lowest score. Range is equal to or greater than standard deviation which comes under cbse syllabus for class 10.
In range the difference between highest and lowest scores is known as crude range. The smallest and greatest observation is called observed range. For example range can be present in entire row or column and multiple row, column.
Range Of Probability (introduction to probability worksheet), is defined as an event is impossible when its probability is zero and when event is there its probability is one. The value of probability is Pr (impossible event) = 0
The probability of event A is denoted by P(A) and it is range from 0 to 1.
The range of distribution and value of function is equal to zero and it is a random variable which is used to differentiate between maximum value and minimum value which is equal to zero.
The three kinds of averages are mean, median and mode. The median is the middle value in the numbers. For example find the mean, median mode and range of the following values:
3,5,8,6
Answer: (3+ 5+8+6)/ 4 = 22/4 = 5.5
The mean is 3.5
median is 8+6= 14/2= 7
mode= none
range = 5
The largest value is 8, the smallest is 3 and their difference is 5.
so, the range is 5.
The output value of a function is called range of a function.
Domain ->function->Range.
