A is true: the absolute value of 0.92 is close to 1, and 0.92 is positive. B is false: correlation can also be negative. C is false: the absolute value of -.17 is closer to 0 than 1; therefore, it is a weak correlation. D is true: the absolute value of .01 is very close to 0, meaning that there is no significant correlation. E is true: correlation can range from -1 (perfect negative) to 1 (perfect positive). F is false: it measures the strength and direction between two numerical variables! In conclusion, A, D, and E are true.
The variation(both the skein values and cost values) has the constant of 4 ie the 1st skein value × 4= the last skein value & the 1st cost value × 4=the last cost value
