If all the values in a dataset are identical, what would be the variance and standard deviation?

  • The variance and standard deviation would be 0
  • The variance and standard deviation would be 1
  • The variance would be 0 but the standard deviation would be 1
  • The variance would be 1 but the standard deviation would be 0
If all the values in a dataset are identical, there is no variation or dispersion in the data. Hence, both the variance and the standard deviation would be zero.
