Let m be the mid-point and I be the upper class limit of a class in a continuous frequency distribution. The lower class limit of the class is

A grouped frequency table with class intervals of equal size using 3-5 (5 included in this interval) as one of the class intervals is constructed for the following data. The frequency of the class 3-5 is

The given cumulative frequency distribution shows the class intervals and their corresponding cumulative frequencies. Then the frequency of class interval 20-30 is

‘Less than’ cumulative frequency table for a given data is as follows. Then, the frequency of class interval 20-30 is

‘More than’ cumulative frequency table for a given data is as follows: Then, the frequency of the class interval 70-80 is

In a bar graph, 0.25 cm length of a bar represents 100 people. Then, the length of bar which represents 2000 people is

In a bar graph if 1 cm represents 30 km, then the length of bar needed to represent 75 km is

In a bar graph, the widths of bars

In a histogram, which of the following is proportional to the frequency of the corresponding class?

For drawing a frequency polygon of a continuous frequency distribution, we plot the points whose ordinates are the frequency of respective classes and abscissa are respectively
