The values along the x-axis show the values from the dataset and the values along the y-axis show the CDF values. Then, we can click the Insert tab along the top ribbon and click Insert Line Chart to produce the following chart: The goal is to get Excel to successfully plot a curve of a piecewise function that looks something like this. The required data will need to be inserted into the excel sheet. First you have to start the excel software. Subsequently, go to the Insert tab > Charts group > Insert Scatter or Bubble Chart tool >. The steps involved in making the chart will be relatively the same in many instances. To do this, initially, select the B6:C8 cells. However it is the medium I have available and I would like to use Excel so that I can tie it into a bunch of work that Ive already done with it. So the excel software may come with a different interface. To visualize this CDF, we can highlight every value in column B. I fully understand that Excel is not the best program to do this type of work. The probability that the random variable will take on a value equal to or less than 8 is.The probability that the random variable will take on a value equal to or less than 7 is.The probability that the random variable will take on a value equal to or less than 6 is.The way we interpret the values is as follows: Next, we can copy and paste this formula down to every other cell in column B: Next, we can calculate the cumulative distribution probability for the first value in the dataset by using the following formula: =NORM.DIST(A2, $F$1, $F$2, TRUE) Next, let’s specify the mean and standard deviation of the distribution: Example: Calculate & Plot CDF in Excelįirst, let’s create the following dataset in Excel: The following example shows how to calculate and plot a CDF in Excel. We can use the following function in Excel to calculate cumulative distribution probabilities: =NORM.DIST(x, MEAN, STANDARD_DEVIATION, TRUE) A cumulative distribution function (CDF) describes the probability that a random variable takes on a value less than or equal to some number.
