Fill in all but one of the above options (the one you are trying to solve for) as follows: N = the total number of times compounded (the number of times compounded per year times the number of years), I% = interest rate (not in decimal form), PV = present value (the amount you invest), PMT = value of payments (0 if you are not making any payments), FV = future value (the amount of money you have at the end of your investment), P/Y = the number of payments per year (the number of times compounded per year if you are not making any payments), C/Y = the number of times compounded per year. If you fill in PV and FV, one must be negative in order for your calculator to find an answer. (Simulating the flow of money between you and the bank.) Make sure you have some kind of value entered in the spot for whichever variable you are solving for or else the calculator will not let you proceed to input values for the rest of the variables.To find a y value from your regression line when given an x value, go to the main calculator screen and call up your function name (VARS, cursor right to Y-VARS, select 1:Function... and Y1 (or whichever function your line is in)) and then open the left parenthesis, type the x value and close your parenthesis. OR... hit CALC (2nd TRACE) and select option 1:value. Then just enter the value for x.

The range of a data set in statistics is the difference between the largest and the smallest values. While range does have different meanings within different areas of statistics and mathematics, this is its most basic definition, and is what is used by the provided calculator. Using the same example:Instructions: Perform a regression analysis by using the Linear Regression Calculator , where the regression equation will be found and a detailed report of the calculations will be provided, along with a scatter plot. All you have to do is type your X and Y data. Optionally, you can add a title and add the name of the variables.The Linear Regression work with steps shows the complete step-by-step calculation for finding the covariance of the two samples $X:4,5,6,7,10$ and $Y:3,8,20,30,12$. For any other samples, just supply two lists of numbers and click on the "GENERATE WORK" button. The grade school students may use this linear regression calculator to generate the work, verify the results derived by hand or do their homework problems efficiently. (Source: ncalculators.com)

Data

You can use this Linear Regression Calculator to find out the equation of the regression line along with the linear correlation coefficient. It also produces the scatter plot with the line of best fit. Enter all known values of X and Y into the form below and click the "Calculate" button to calculate the linear regression equation. Click on the "Reset" to clear the results and enter new data.Linear Regression calculator uses the least squares method to find the line of best fit for a sets of data `X` and `Y` or the linear relationship between two dataset. It estimates the value of a dependent variable `Y` from a given independent variable `X`. It's an online statistics and probability tool requires two sets of data `X` and `Y` and finds the relationship between two variables by fitting a linear equation to observed data.

is a model of the relationship between a dependent variable `y` and independent variables `x` by linear prediction function $\hat {y}=a+bx$. Linear functions are used to model the data in linear regression and the unknown model parameters are estimated from the data. Such method of modeling data is known as linear models. For more two or more variables, this modeling is called .is the line $\hat {y}=a+bx$ that makes the vertical distance from the data points to the regression line as small as possible. We call it "least squares" because the best line of fit is one that minimizes the sum of squares of the errors. So, the line of best fit is the least squares regression line $\hat {y}=a+bx$, where $b$ is the slope of the line and `a` is the `Y`-intercept. Linear regression has many applications. If the goal is a prediction, linear regression can be used to fit a predictive model to a data set of values of the response and explanatory variables. Linear regression can help in analyzing the impact of varied factors on business sales and profits. For example, predictive analytics, operation efficiency, correcting errors, etc. By using this concept, we can analyze the marketing effectiveness, pricing, and promotions on sales of a product.
