This statement is true.

The mean deviation about median is a measure of dispersion that indicates how far the observations deviate from the median on average. For a standard normal distribution, the median is 0, and the mean deviation about median is equal to 0.675. This value can be calculated using the formula:

Mean deviation about median = 2/π ≈ 0.6745

Therefore, the statement "The mean deviation about median of a standard normal variate is 0.675" is true, with slight rounding error.
