How to find the mean for each specified range in a table without writing multiple lines of the same code?

I have this table imported into Matlab and im trying to find the mean for each province and year, using the numbers in the "VALUE" column.

Example, for all rows that have "2015" in column A and "Quebec" in column B, calculate the mean using the values in column D.

stats1=rmmissing(stats1,'DataVariables',{'VALUE'})
stats1 = sortrows(stats1,'REF_DATE','ascend');
stats1 = sortrows(stats1,'GEO','ascend');
AB2015=mean(stats1{1:5,4})
AB2015 =

    9.320

I used this method, and it works but I need to find the mean for each year and province so it seems like it would be very repetitive and long. Im wondering if there is an easier way to do this?

Like I told you before, use groupsummary (see also findgroups )

In addition to groupsummary you might also look at grpstats and splitapply
