What is a multiple bar diagram?
Multiple bar diagrams are those diagrams which show two or more sets of data simultaneously.
Data represented through arithmetic line graph help in understanding:
Width of bars in a bar diagram need not be equal.
Width of rectangles in a histogram should essentially be equal.
Histogram can only be formed with continuous classification of data.
Histogram and column diagram are the same method of presentaton of data.
Mode of a frequency distribution can be known graphically with the help of histogram.
Median of a frequency distribution cannot be known from the ogives.
What kind of diagrams are more effective in representing the following:
(i) Monthly rainfall in a year.
