absolute value : The distance between a real number and zero on a number line. additive inverse : The opposite of a number. When added together, the sum is zero. algebraic expression : A collection of numbers and variables with at least one arithmetic operation. associative property : The grouping of terms within expressions involving addition or multiplication does not change the value. Ex: (a+b) + c = a + (b+c) axis of symmetry : The line that divides a graph into two symmetrical pa...

We can assess the constant variance assumption in linear regression by plotting the residuals vs. fitted values. - True If one confidence interval in the pairwise comparison in ANOVA includes zero, we conclude that the two corresponding means are plausibly equal. - True The assumption of normality is not required in linear regression to make inference on the regression coefficients. - False (Explanation: is required) We cannot estimate a multiple linear regression model if t...

If (-2,4) is a point on a graph that is symmetric with respect to y-axis, then the point _________ is also on the graph. (2,4) If the point (9,-14) is a graph of a function f, then f(4) = -14 The graph of y=f(x+5)is found by horizontally shifting the graph of y=f(x) five units to the ____________________ left If f(2)=12 and g(2)=4 the (g-f)(2)= 4-12=-8 T/F A line with undefined slope is perpendicular to every line with slope zero. True T/F If (1,2) is a po...

Regression Analysis - Regression analysis is a simple way to investigate the relationship between 2 or more variables in a non-deterministic way. Response/Target Variable (Y) - This is a variable we're interested in understanding, modeling or testing This is a random variable. It varies with changes in the predictor(s) 2. Predicting/Explanatory (independent) Variables(Xs ~ X1, X2) - These are variables we think might be useful in predicting or modeling the response variable This i...
