Question

Marks of 20 students have been given below 18, 16,18, 17,18, 16, 18, 17,18, 16, 18, 17,18, 17, 20, 18, 20, 20,18,18. Create frequency distribution table and find the mode​

Answer 1

Step-by-step explanation:

Mean = Sum of marks / No. of students

= 18+16+18+17+18+16+18+17+18+16+18+17+18+17+20+18+20+20+18+18

= 356/20

=17.8

Mode nikalne ke liye humhe pehle ascending order me likhna hoga

Arrange in ascending order

16,16,16,17,17,17,17,18,18,18,18,18,18,18,18,18,18,20,20,20

Mode = 18 ( It occurs maximum 10 times )
