It will show that it’s valued at somewhere around $2500 by the dot in the green circle. Want to know what it will be worth in 2030? You can get a rough idea by adding 10 periods, or years, to the trendline in the Forecast Forward field. Now you have a linear regression trendline that shows you the general growth of the stock value over 20 years. Feel free to work with the Excel formatting to make the line look nice. The Linear trendline option will already be selected. ![]() The Format Trendline menu will open on the right. When you do, a sub-menu will open.Select Add Trendline. This can be a little tricky, so keep trying if you don’t get it on the first try. Once the graph is built and you’ve customized the Excel chart to look the way you want it, right-click on a single data point. Select the down arrow next to it.Select the first scatter graph with just dots and no lines. Select Insert in the main toolbar.Look for the icon of a graph with just dots on it. Then, in Excel, select both columns of data by selecting and holding on the top-left number and dragging down to the bottom-most number in the right column. You can copy and paste the data into Excel so you can play along. Our example will have Time in years and Stock Value in dollars. Then we can do some neat things with the trendline and see what it means.Ĭreate 2 columns of data in Excel. The first step is to create a scatter plot. Let’s assume you haven’t learned all about Excel yet. How To Create An Excel Scatter Plot With Linear Regression Trendline # Now we know those words are actually English and what they mean. That line is a simple linear regression trendline through a scatter plot. The dots could be all over the place or scattered.Ĭould we draw a line through the dots that would show a trend? Let’s call that a trendline. Then we put those measurements on a graph or plot. ![]() That’s fairly simple because we’re only measuring how much we change one thing or one variable. We figure it out by looking at how much the stock earned over several years. If we bought a stock for $1 and in one year its value went up to $100, does that mean every year the value will go up another $100? Does that mean in 25 years it will be valued at $2500? We don’t know. But how dependent is the value of a stock on time passed? We can’t control those other things, but we can control when we sell the stock, so we control the time variable. We know that the value of a stock is changed by time passing, among other things. X will be time in years and Y will be the value in dollars. Let’s use the example of tracking the value of a single share in the stock market over the years. Regression, in math, means figuring out how much one thing depends on another thing. Ok, now that the nerds are gone we’ll explain linear regression. If you know what a linear regression trendline is, skip ahead.
