Question

Calculate mode for the following data... 0-10, 10-20, 20-30, 30-40, 40-50, 50-60, 60-70 , Frequency 4,13,21,44,33,22,7

Answer 1

Step-by-step explanation:

For calculating the mode plot the class intervals on x axis and frequency on y axis.

draw bar graphs for each data.

Now take the longest bar and draw a cross joining the 2 adjecent bars to the longest one.

draw a perpendicular from the intersection of the cross down to the x axis.

The number u get on the x axis is the mode.

hope this helps:)
