Once a line of best fit has been placed upon a scatter graph it is straightforward to find the equation. The general equation of a straight line is: y=mx+cy = mx + cy=mx+c Wheremis the slope (gradient) of the line andcis they-intercept. To obtain the gradient, find two points up...
Coefficient of Determination is a useful measure for evaluating the strength of a relationship between two variables. Still, it should be interpreted in conjunction with other statistical measures and with consideration of other factors that may be affecting the relationship. How to Find Correlation Coe...
such as multiplication and linear graphing, the TI-84 Plus can find solutions for problems in algebra, calculus, physics and geometry. It can also calculate statistics functions, including finding the correlation coefficient and coefficient of determination...
Determine the leading coefficients of the two polynomials. The leading coefficient of a polynomial is the constant that is multiplied by the term with highest degree. The leading coefficient of both polynomials in the example equation is 1. Calculate the horizontal asymptotes of the equation using t...

To determine if we are looking for a maximum or minimum, we look to see if theavalue of our quadratic equation is positive or negative. Theais the coefficient of the(x - h)squared term. y=a(x−h)2+kIfa<0we are looking for a maximum. The graph of the function opens downIfa>0we...
How to Find the Slopes of Lines Parallel and Perpendicular to a Line Given in the Form Ax + By = C: Example 2 Find the slopes of lines that are parallel to and that are perpendicular to the line5x−4y=20. Step 1:Rearrange the equation to the s...
How to find the irrational roots of a polynomial? Polynomial with Irrational Root An irrational number is a number with countless or infinite decimals, so, irrational numbers need to be written with fractions, remember: a polynomial can have irrational roots. Answer and Explanation: 1 Become a...
To understand how we are getting this value, we need to find it manually. This will clear our doubts. As we know the correlation coefficient is: =Coveriancexy/(Stdx*Stdy) First, we need to calculate the covariance. We can use the COVERIACE.S function of excel to calculate it. ...
A value of 0.0 suggests that asset prices aren't a function of dependency on the index. Investopedia / Julie Bang Understanding the Coefficient of Determination The coefficient of determination is a measurement that's used to explain how much the variability of one factor is caused by its relati...
