<P> A different tabulation scheme aggregates values into bins such that each bin encompasses a range of values . For example, the heights of the students in a class could be organized into the following frequency table . </P> <Table> <Tr> <Th> Height range </Th> <Th> Number of students </Th> <Th> Cumulative number </Th> </Tr> <Tr> <Td> less than 5.0 feet </Td> <Td> 25 </Td> <Td> 25 </Td> </Tr> <Tr> <Td> 5.0--5.5 feet </Td> <Td> 35 </Td> <Td> 60 </Td> </Tr> <Tr> <Td> 5.5--6.0 feet </Td> <Td> 20 </Td> <Td> 80 </Td> </Tr> <Tr> <Td> 6.0--6.5 feet </Td> <Td> 20 </Td> <Td> 100 </Td> </Tr> </Table> <Tr> <Th> Height range </Th> <Th> Number of students </Th> <Th> Cumulative number </Th> </Tr> <Tr> <Td> less than 5.0 feet </Td> <Td> 25 </Td> <Td> 25 </Td> </Tr>

Frequency distributions indicate the percentage of times that variables are observed
