Hello, so I am new to Matlab and I am doing a project where I have to find the average of my column "weights" depending on the column "sex". So it is pretty much finsing the average weight of males and females. This is how the table looks like :

The groupsummary function is also an option —
g = {'Male';'Female'};
allSamples = table(randi([60 99],20,1),randi([160 210],20,1),g(randi([1,2],20,1)), 'VariableNames',{'Weight','Height','Sex'})
allSamples = 20×3 table
Weight Height Sex ______ ______ __________ 74 169 {'Female'} 90 165 {'Female'} 62 167 {'Female'} 82 170 {'Female'} 72 179 {'Male' } 63 207 {'Female'} 89 189 {'Female'} 90 188 {'Female'} 86 170 {'Female'} 88 177 {'Male' } 79 185 {'Male' } 81 197 {'Male' } 65 163 {'Female'} 89 163 {'Male' } 65 206 {'Female'} 70 168 {'Male' }
G = groupsummary(allSamples, 'Sex','mean','Weight')
G = 2×3 table
Sex GroupCount mean_Weight __________ __________ ___________ {'Female'} 12 77 {'Male' } 8 80.875
.
