Calculate the coefficient of concurrent deviations from the data given below 1988 Year 1985 1986 1987 1989 1990 1991 1992 1993 Supply 160 164 172 182 166 170 178 192 186 Price 292 280 260 234 266 254 230 190 200 Since there is no sign for the first value of X and Y, N is always taken to be one less than the actual number of pairs of observations. For example if 10 pairs of observations are given, n would be taken to be 9 while applying concurrent deviation method.
