Question

For 15 pairs of observations, the
number of concurrent deviations are
12. what is the value of the coefficient
of concurrent deviation?​

Answer 1

Step-by-step explanation:

12. The deviation in the x-value and the corresponding y-value is known to be concurrent if both the deviations have the same sign. If (2c–m) > 0, then we take the positive sign both inside and outside the radical sign and if (2c–m) < 0, we are to consider the negative sign both inside and outside the radical sign.
