frequency

Step-by-step explanation:

Planck showed that the energy that is emitted or absorbed by an object is proportional to the _       frequency of the radiation.

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
