Question

Create MATLAB code that will run statistics (min,max,mean,mode) on a selected column (just 1 column, not all of them). For example, if I want to run the statistics on the column 'age', it will only run it on that column and not the others. The file is cardio_dataset and each column is separated by commas.

The sample file is the following:

age,gender,height,weight,sys_bp,dia_bp,cholesterol_lvl,gluc_lvl,smoke,alco,active,cardio

50.3917808219178,2,168,62,110,80,1,1,0,0,1,0

55.4191780821918,1,156,85,140,90,3,1,0,0,1,1

51.6630136986301,1,165,64,130,70,3,1,0,0,0,1

48.2821917808219,2,169,82,150,100,1,1,0,0,1,1

47.8739726027397,1,156,56,100,60,1,1,0,0,0,0

60.0383561643836,1,151,67,120,80,2,2,0,0,0,0

60.5835616438356,1,157,93,130,80,3,1,0,0,1,0

61.8739726027397,2,178,95,130,90,3,3,0,0,1,1

48.4054794520548,1,158,71,110,70,1,1,0,0,1,0
