In Histogram if the classes of unequal width then the heights of the rectangles must be proportional to the frequency densities.
In representing simple frequency distributions of a discrete variable
Class boundaries should be considered to be the real limits for the class interval
“Cumulative Frequency” only refers to the
Most extreme values which would ever be included in a class interval are called
The number of types of cumulative frequency is
Frequency density is used in the construction of
Vertical bar chart may appear somewhat alike
In the construction of a frequency distribution, it is generally preferable to have classes of
For determining the class frequencies it is necessary that these classes are
The number of observation falling within a class is called
For the construction of a grouped frequency distribution
In all Statistical and diagrams involving end points of classes
The number of “ Frequency distribution” is
The graphical representation of a cumulative frequency distribution is called
(Class frequency) / (width of the class) is defined as
An approximate idea of the shape of frequency curve is given by
In general the number of types of tabulation are
Unequal widths of classes in the frequency distribution do not cause any difficulty in the construction of
To find the number of observations less than any given value
