I'm not sure what is SDI, but I think the answer to base question about the Data Statistics item in the Tools menu of the traditional figure is "No"...the uifigure which App Designer uses doesn't support the 'figure' MenuBar --
>> hUIF=uifigure;
>> set(hUIF)
...
MenuBar: {'none' 'figure'}
...
>> hUIF.MenuBar='figure';
Functionality not supported with figures created with the uifigure function.

While it appears that it is an allowed value, trying to bring it back fails.
It appears the tool is another small app being called but I am unable to find the actual code/function being called by the menu callback -- it may be buried inside something else or in some inscrutable internal function.
The best I can think of would be to have to build a similar functionality; it shouldn't be too awful hard, if one has the Statistics TB there is grpstats which can be used to calculate a selected set of statistics on a dataset; the grouping variable(s) can be set to the empty [] array to be a global calculation without grouping. Capturing this output and formatting a table similar to the menu tool wouldn't be terribly difficult.
As with so much else that has been left behind, I'd suggest to submit service request to Mathworks on how to restore the functionality in present release; perhaps they would let us know how it is presently implemented that could be picked up; otherwise at least get it into the enhancement list and on the ever-growing list of complaints about functionality regression.
