Question

plz someone tell me when we have to draw krink mark on the graph in histogram.​

Answer 1

you draw a kink when the class interval does not start from origin to show that there are missing class intervals in between.

for eg,if the class intervals are 20-30,30-40,40-50,....                                               you draw a kink from 0-20

but if it starts from 0-10,10-20,20-30,....

you do not draw the kink

also if it starts from 10-20,20-30,30-40,...

when you draw the graph it will be 0-10,10-20,20-30,...

so you don't draw the kink
