To find mean for grouped data
There are three methods to find mean for a frequency distribution. (i) Direct method: where x is the mid-interval f is the frequency M is the mean (ii) Short-cut method: where A = assumed mean d = x - A (iii) Step-deviation method: where i = class size We illustrate each of these methods w..

Since carbon and oxygen have different values of electronegativity, the bond between carbon and oxygen is polar. The electron density around the oxygen atom is increased which causes the development of partial positive charge ( d +) on carbon and a partial negative charge ( d -) on oxygen..

Tutors are very well educated who knows what they are doing and is very good at math. Also I like the way they teach me - Baker
Turtors are so good, and patient and most important knows their stuff. They really tutor in a very professional way. Their system is unique and they really knows how to explain and made sure you undertand. They even put stuff from a book into the white board, just to show me how the process of my question - Paul
It was fun! It showed me a easier way to do multiplication with bigger numbers,Thank you all - Christian
The tutor made sure i was learning and made sure i was paying attention, superbbbb session. Thank u
