Value – the value of a digit according to its place in a number. Example : 400, 60, 6. Since the averages are the same, can we assume that the students in both classes all did pretty much the same on the exam?. The answer is… No.. The average (mean) does not tell us anything about the distribution or variation in the grades.. and their Units. PHYSICAL QUANTITY . refers to a quantity that can be measured.. Measured in SI Units which means International System of Units used all over the world. PREFIX. A prefix is added to a unit to change the value of the unit. . Using powers is a shorthand way of writing big numbers.. e.g. 10. 3. . - this way of writing a number is called ‘standard form’..
