Relation between mean and standard deviation?
Standard deviation is the variance from the mean of the data.
What is the difference between standard deviation and mean?
The mean is the average value and the standard deviation is the variation from the mean value.
Difference between standard deviation and mean devition?
The mean deviation (also called the mean absolute deviation) is the mean of the absolute deviations of a set of data about the data's mean. The standard deviation sigma of a probability distribution is defined as the square root of the variance sigma^2,
What does standard deviation help you find?
Standard deviation helps you identify the relative level of variation from the mean or equation approximating the relationship in the data set. In a normal distribution 1 standard deviation left or right of the mean = 68.2% of the data 2 standard deviations left or right of the mean = 95.4% of the data 3 standard deviations left or right of the mean = 99.6% of the data
Does standard deviation answer have to be between 3?
No, since "between 3" doesn't mean anything. Do you mean between -3 and +3?
