Question

The standard deviation is a resistant measure of spread. true or false

Answer 1

True; Standard deviation is the measure of how spread out numbers are.It is a measure that is used to quantify the amount of variation or dispersion of a set of data values. It is calculated by getting the square root of variance by determining the variation between each data value relative to the mean. Therefore, if the points are further from the mean then the standard deviation is higher and vicevarsa.

Answer 2

False,  
This is on the grounds that whenever a number changes, the standard deviation changes. It is likewise influenced by exceptions called outliers. The term applies to measures of focal propensity (evaluations of the focal point of a populace). The middle is impervious to the impacts of exceptions while the mean isn't. A standard deviation is a measure of scattering, in this way the expression "resistant" does not have any significant bearing.
