FIND ARITHMETIC MEAN BY DIRECT METHOD WORKSHEET

Question 1 :

Calculate the Arithmetic mean of the following data by direct method.

 x51015202530 f457432

Question 2 :

The following data give the number of boys of a particular age in a class of 40 students. Calculate the mean age of the students

 Age (in years)131415161718 Number of students3891163

Question 3 :

Calculate the Arithmetic mean of the following data:

 x1525354555657585 f12201514161178 x51015202530Total f457432N  =  25 fx2050105807560∑fx  =  390

Arithmetic mean :

∑fx/N

= 390/25

= 15.6

 x131415161718Total f3891163N  =  40 fx3911213517610254∑fx  =  618

Mean age of the students :

∑fx/N

= 618/40

= 15.45 years

 x1525354555657585Total f12201514161178N  =  103 fx180500525630880715525680∑fx  =  4635

Arithmetic mean :

∑fx/N

= 4635/103

= 45 Apart from the stuff given above, if you need any other stuff in math, please use our google custom search here.
