|
a measure of variability that describes an average distance of every score from the mean

|
numerical methods used to determine whether research data support a hypothesis or whether results were due to chance

Detailed explanation-1: -The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each score lies from the mean. The larger the standard deviation, the more variable the data set is.
Detailed explanation-2: -The standard deviation is the most commonly used measure of variability because it includes all the scores of the data set in the calculation, and it is reported in the original units of measurement. It tells us the average (or standard) distance of each score from the mean of the distribution.
Detailed explanation-3: -The standard deviation is the most commonly used measure for variability. This measure is related to the distance between the observations and the mean.
Detailed explanation-4: -The mean absolute deviation (MAD) is the mean (average) distance between each data value and the mean of the data set.
Detailed explanation-5: -The standard deviation measures the dispersion or variation of the values of a variable around its mean value (arithmetic mean). Put simply, the standard deviation is the average distance from the mean value of all values in a set of data.
