Select the data table range, including your formula, variable values cells, and empty cells for the results (D2:E8).

If you want to examine the impact of the variable values on other formulas that refer to the same input cell, enter the additional formula(s) to the right of the first formula, as shown in this example. We choose the latter option, and enter this simple formula in E2: =B8

Or, link this cell to the formula in your original dataset (if you decide to change the formula in the future, you would need to update only one cell).

Type your formula in the cell one row above and one cell to the right of the variable values (E2 in our case).

In this example, we are going to create a column-oriented data table, so we type our variable values in a column (D3:D8) and leave at least one blank column to the right for the outcomes.

Enter the variable values either in one column or across one row.

Here are the steps to make a one-variable data table:

B2 is the variable you want to test (initial investment).Īnd now, let's do a simple What-If analysis to see what your savings will be in 5 years depending on the amount of your initial investment, ranging from $1,000 to $6,000.

B8 contains the FV formula that calculates the closing balance.

To check different options, you've built the following compound interest calculator where: Suppose you are considering depositing your savings in a bank, which pays 5% interest that compounds monthly. To help you better understand this feature, we are going to follow a specific example rather than describing generic steps.

One variable data table in Excel allows testing a series of values for a single input cell and shows how those values influence the result of a related formula.

How to create a one variable data table in Excel If you are looking to learn about many possible ways to create, clear and format a regular Excel table, not data table, please check out this tutorial: How to make and use a table in Excel. A data table isn't the same thing as an Excel table, which is purposed for managing a group of related data. Just enter you own examples above and they will be calculated immediately step-by-step.Note. To find the equation of the function, you have to insert a point and get an equation which gives the y-axis intercept.

To calculate the slope m, use the formulaĪs we can see, the slope was calculated first. This means: You calculate the difference of the y-coordinates and divide it by the difference of the x-coordinates. How to calculate the equation of a linear function from two given points?įirst, we have to calculate the slope m by inserting the x- and y- coordinates of the points into the formula. Therefore, the equation of the function is General form of the linear function: f(x)=mx+b Here is an example: Lets assume we know that our function has slope and goes through (-2|5).Ĭalculate the y-axis intercept b by inserting: the one coordinate for x and the other one for f(x). You have to insert the point into the equation, i.e. How to calculate the equation of the line from a point and the slope? If you take a look on the function graphs, you see that intersects the y-axis at intersects the y-axis at. As the name says, it says where the function cuts the y-axis.

The y-line intercept is the number at the end of the function. What is the y-line intercept of a linear function? This means whenever we go one square to the right, we have to go three squares down to be on the graph again. If we go one square to the right of any point on the graph, we have to go two squares up to be on the graph again.Īnother example, this time with negative slope:

It says how may units you have to go up / down if you go one unit to the right. The slope of a linear function corresponds to the number in front of the x. The graph of a linear function is always a line.Ī similar word to linear function is linear correlation. Here is an example:ĭein Browser unterstützt den HTML-Canvas-Tag nicht. The general form of a linear function is, where m is the slope and b is the y-axis intercept.

A linear function is a function whose graph is a line.
