In statistics, the Mode is the value that has most appearance in a set of data values.
For example , a set of data 10, 12, 11, 10, 15, 20, 19, 21, 11, 9, 10 , the mode is "10 occures 3 times".
Mode can be multiple , if multiple values has highest occurance , follow the below set of data
2,3,4,4,4,4,5,5,6,7,7,8,9,9,9,9,10,11,12,12.The mode is 4 occures 4 times, 9 occures 4 times.
Standard Deviations are of two types , standard deviation and sample standard deviation. During calculating the population standard deviation, we divide by n, the number of data values. For calculating the sample standard deviation, we divide by n 1.
