What Is Mean What Is Mean In mathematics the meaning of mean is same as the meaning of average or in other words meanings of mean is adding all the values and then divide these values by the total number of values are called mean. Mean is the term which we use in statistic in place of average and there are various types of averages in statistic but the most commons are mean, median and mode. Now we elaborate What is the Mean in mathematics The meaning of mean in mathematics or we can say in statistic is same as the meaning of normal average that we take means in average we are adding all the numbers or value of all quantities and then divide this by the total number of quantities and in mean we do the same procedure as we doing while finding the average. Formula of mean is Mean = add all the numbers or quantities/ total number of quantities Now to understand the meaning of mean more clearly we are taking some examples

1. Suppose that we have some numbers 23, 12, 2, 43, 56, 13, 76 and 32 now we have to find the mean of these numbers. Then first we have to add all the numbers So, 23 + 12 + 2 + 43 + 56 + 13 + 76 + 32 = 257 Now we seeing that how many numbers of element are present, so there are 8 elements are present now we have to apply the formula of mean. Then, mean = 257/ 8 So, mean = 32.125 This is the final result and this way we are going to find the mean in mathematic. 2. Let’s take another example suppose that there are 10 students in a class and a list of marks all students in maths subject are given below Student A got 70 marks in maths Student B got 65 marks in maths Student C got 76 marks in maths Student D got 80 marks in maths Student E got 87 marks in maths Student F got 50 marks in maths Student G got 79 marks in maths

Student H got 90 marks in maths Student I got 40 marks in maths And student J got 60 marks in maths Now find the mean of all the students So there are 10 students in class Now add the marks of all the student of maths subject So, 70 + 65 + 76 + 80 + 87 + 50 + 79 + 90 + 40 + 60 = 697 Now we have to apply the formula of mean to find the result Mean = adding all the marks of students in maths / total number of students Mean = 697 / 10 Mean = 69.7 This is the final result. Now we can say that the meaning of mean and average is same in mathematics and these are two different names given to the same procedure. In normal we say average but in statistic we say mean so average is also called mean.
