Dependent variable - ANSthink of the independent variable as the input and the dependent variable as the output. Stated another way, the independent variable's input influences what output, or outcome, you get from the dependent variable. independent variable - ANSIs the variable that explains, influences, or affects the other variable. The independent variable is put on the x-axis, or horizontal axis, on a graph. Quantitative variables. - ANSA variable that is measured on a number scale; A variable with a numeric value. Qualitative variables - ANSA variable that is not numeric; also, called a categorical variable. A qualitative variable describes data that fits into categories. Functions - ANSA relation based on a set of inputs and a set of possible outputs where each input is related to exactly one output. Inverse function - ANSInverse functions are basically functions that "reverse" each other. An inverse function swaps the input and output variables. independent variable and dependent variable relationship - ANSAn independent variable explains changes in the dependent variable, while a dependent variable measures the changes. rate of change - ANS-Rate of change is the change in y-values over the change in x-values. -Rise over run instantaneous rate of change - ANSThe rate of change at a particular moment, as opposed to average rate of change, which is a change over a period of time. Take what you miss and divide it by the Goal for percentages - ANSExample: If the goal is 500 and you miss it by 50 do 50/500= 0.1. Which would be 10% Take what you surpass and divide it by the Goal for percentages - ANSExample: If the goal is 190,000 and you surpass it by 10,000 do 10,000/190,000=5.26. Which would be 5.26%
