Construction of a Histogram of a Continuous Grouped Frequency Distribution with Equal Intervals of C
Construction of a Histogram of a Continuous Grouped Frequency Distribution with Equal Intervals of Class
1. Take a graph and draw two perpendicular linesÂ such that one of them is horizontal and the other is a vertical line. O is the point of intersection. Mention them as OX and OY respectively.
2. Take OX as x-axis and OY as y-axis.Â
3. Take a suitable scale to represent class intervalsÂ on x-axis and mark the class limits on it.
4. Take a suitable scale to represent frequencies.Â Take points on the y-axis for frequencies.
5. Construct rectangles with the base as class intervals and height proportional to their frequencies.
