T= readmatrix('Participants.csv');

x=T(:,1);

y=T(:,2);

z=T(:,3);

scatter3(x,y,z)

I would show the corrolations between variables.

T1= readtable('Participants_1.xlsx'); 
T1.Gender = categorical(T1.Gender);
T1.Gender = double(T1.Gender);
T2=table2array(T1);
imagesc(corrcoef(T2)); colorbar
xticks([1 2 3 4 5])
xticklabels({'Age','Gender','Height','Weight','BMI'})
yticks([1 2 3 4 5])
yticklabels({'Age','Gender','Height','Weight','BMI'})

I think we dont need to plot the height and weight since BMI there.

I am not an expert in your field. If you feel you need to drop the values, you can easily do so.

T1= readtable('Participants_1.xlsx');  T1 = removevars(T1, {'Height_cm_','Weight_kg_'});
T1.Gender = categorical(T1.Gender);
T1.Gender = double(T1.Gender);
T2=table2array(T1);
%%
imagesc(corrcoef(T2)); colorbar
xticks([1 2 3])
xticklabels({'Age','Gender','BMI'})
yticks([1 2 3])
yticklabels({'Age','Gender','BMI'})
