Ответ:
b) symmetrical without outliers
Step-by-step explanation:
In statistics, when we want to compare the center and variability of a given data sets, there are particular measures that we use for this purpose.
Such measures include:
a. Mean
b. Mean Absolute Deviation
c. Median
d. Mode
e. Interquartile mean
Mean and Mean Absolute Deviation are measures of the center and variability of symmetrical data. This symmetrical data does not have any outliers present in them. This data is also continuous and well distributed.
