, NCSSM PLACEMENT TEST QUESTIONS AND ANSWERS
correlation - (answer)a measure of the strength an direction of the relationship between two variables
or data sets
correlation coefficient - (answer)a number r greater than or equal to -1 and less than or equal to 1, that
describes how closely the points in a scatter plot cluster around the line of best fit.
linear regression - (answer)a statistical method used to fit a linear model to a given data set
residual - (answer)the signed vertical distance between a data point and a line of fit
X-Intercept - (answer)The x-coordinate(s) of the point(s) where a graph intersects the x-axis.
Y-Intercept - (answer)The y-coordinate(s) of the point(s) where a graph intersects the y-axis.
Linear Function - (answer)A function that can be written in the form y=mx+b, where x is the
independent variable and m and b are real numbers. Its graph is a line.
