Note: The given class intervals are not continuous. Therefore, we first modify the distribution as continuous.
A random survey of the number of cbse classes in kalyan formula of various age groups playing in a park was found as follows: D raw a histogram to represent the above data.
Here, the class sizes are different therefore, we calculate the adjusted frequencies corresponding to each rectangle. Note: I. In a histogram, the areas of the rectangles are proportional to the corresponding frequencies. If the widths of all the rectangles kalan equal, then the lengths of the rectangles are cbse classes in kalyan formula to the frequencies. In case the rectangles have different widths then we need to make modifications in the lengths of the Cbse Classes In Kalyan Tab rectangles such that their areas are proportional to the frequencies.
Therefore, finding the adjusted frequencies we have: ii The maximum frequency is 44, which is corresponding to cpasses class interval 6 � 8.
