The marks obtained by 30 students of Class X of a certain school in a Mathematics paper consisting of 100 marks are presented in table below. Find the mean of the marks obtained by the students.

Text Solution

Verified by Experts

Mean `= (sumf_ix_i)/(sumf_i)`
Please refer to video for the calculation table. Here, `sumf_ix_i = 10+20+108+160+150+112+240+280+72+80+176+276+95=1779`
`sumf_i = 30`
So, Mean `= 1779/30 = 59.3`
