In Data Science, we come across terms like mean, mode, median, variance, standard deviation and many more. These arithmetic functions are very useful for solving of data science problems. Let us understand them in some detail. What is mean? Mean is the average of the numbers. It is basically the sum of all the numbers, divided by how many numbers are there. Example:  We have numbers as follows: 2 ,3 ,4 and 7. First step: sum of all the numbers: 2 + 3 + 4 + 7 = 16 Second step: total numbers in the series: 4 Third step: Divide the sum of all numbers by total numbers in the series: 16 / 4 = 4 Thus we get the mean as 4. What is Mean, Mode. Median, Variance and Standard Deviation? What is mode? The number which appears the most often in a given set of numbers is called mode. Example:  ( 4 , 5,  4 , 6,  4 , 5,  4 , 5, 6,  4 ) In the above series of numbers, we have number 4 as the mode as it is occurring the maximum time that is 5 times....
