Also, the physical activity behavior (AG) was measured and classified into three classes classified: 1 = rarely, 2 = sometimes, 3 = regularly. The results are shown in cross tabulation below:

   ————- ——– ——– ——– frequencies SB = 1 SB = 2 SB = 3 AG = 1 4 12 14 AG = 2 13 25 12 AG = 3 8 8 4 ————- ——– ——– ——–

   On what scale is the variable AG represented?
