B = slope of the line (rise/run: when you are predicting y, given x, all you need to do is input the given x value, the using the formula, we will find the corresponding y value. Positive and negative relationships: a positive relationship indicates that there is a direct relationship between the variables. A negative relationship indicates that there is an inverse relationship between x and y: the slope of the li(cid:374)e tells us (cid:449)hethe(cid:396) it"s positi(cid:448)e o(cid:396) negative. Correlation: it"s a topi(cid:272) that deal (cid:449)ith the di(cid:396)e(cid:272)tio(cid:374) a(cid:374)d deg(cid:396)ee of the (cid:396)elatio(cid:374)ship direction referring to whether its negative/positive and degree referring to the magnitude/strength of the relationship - which can vary from non-existent to perfect.
