Question

Draw a histogram and frequency polygon for the marks of students given below:- Marks 0-10 ,10-30 30-45,45-50 50-60 and Students :- 8, 32, 18, 9, 6,

Answer 1

here we have to use the adjusted frequency formula because the class intervals( marks) are not equal.You can draw a histogram and frequency polygon using the class intervals in x axis (marks) and adjusted frequency in y axis (number of students).Don't use A.F( adjusted frequency). write adjusted frequency itself.

sorry for the delay... hope this helps you..
