How to Make Cumulative Distribution Graph in Excel

Steps:

  • Select cell D5 and enter the following:
=AVERAGE(C5:C11)
  • Press Enter.

  • We will get the mean of the values.
  • Select cell E5 and enter the following formula:
=STDEV(C5:C11)
  • Press Enter.

  • We will get the standard deviation of the values.
  • Choose cell F5 and enter the following formula:
=NORM.DIST(C5,$D$5,$E$5,TRUE)
  • We will have our cumulative density function value for the value in cell C5.
  • Convert it from general to percentage format.

  • Lower the cursor to autofill the rest of the cells.

  • Select the Marks and Cumulative Distribution columns.
  • Go to the Insert tab.
  • From the Charts option, select Insert Scatter or Bubble Chart.
  • Select any of the scatter charts suitable for you.

  • We will have the Cumulative Distribution graph for the data.
