class upper under Total under 2.0 2.0 - 3.0 over 3.0 total 0.117 0.207 0.145 0.469 0.338 0.090 0.103 0.531 0.455 0.297 0.248 1.000 Probability 0.117

Formula Reference:

G H J K class upper under Total under 2.0 0.117 0.338 =SUM(H7:H8) 2.0 - 3.0 0.207 0.09 =SUM(17:18) over 3.0 0.145 0.103 =SUM(J7:J8) total =SUM(H7:J7) =SUM(H8:J8) =SUM(H9:J9) Probability =0.117/1
