how to plot a graph in excel with formula

This will help to find the variation of the values among a data set. The normal distribution function is a statistical function that helps to get a distribution of values according to a mean value. By using this, we can find the normal distribution. Now for the Normal distribution graph in excel, we have the mean and standard deviation of the given data. You will get the standard deviation value of the given data as below.The standard deviation is calculated by using the formula =STDEV(C2:C15).

You will get the mean value of the given data as below.

Here we applied the formula =AVERAGE (C2:C15) where column C consists of the marks of each student.

To find the mean, please apply the average function. To find the normal distribution, we need two more pieces of data that is the mean and standard deviation. If you would like to know the different formulas that Excel uses for different types of trend lines, you can use the online Help system to search for 'equations for calculating trendlines.Excel functions, formula, charts, formatting creating excel dashboard & others How to Calculate Normal Distribution in Excel?īelow is the data given with students’ names and their marks in a particular subject.īy using this data, let’s try to find the normal distribution. No more guessing! Once you know the formula, you can turn off the formula display if you want it off. You can then use this formula to determine points, as well. The result is that Excel shows a formula, on the chart, that represents how it calculated each point along the line.

Make sure the Display Equation on Chart check box is selected.

Make sure the regression type you want to use is selected.

Excel displays the Add Trendline dialog box.

Choose the Add Trendline option from the Context menu.Right-click on the data series in question.Rather than visually trying to figure out where a point falls, you can follow these steps: At some point, you may want to actually figure out how Excel does its calculations to determine where to actually plot points along the line. When creating charts from Excel data, you can smooth out the lines between data points by using any number of methods.
