The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
What is the function for standard deviation in R?
This function computes the standard deviation of the values in x . If na. rm is TRUE then missing values are removed before computation proceeds. If x is a matrix or a data frame, a vector of the standard deviation of the columns is returned.
How do I calculate the mode?
To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.
How do you find the mean of a row in R?
