Enter your data in a column
Calculate the mean with `=AVERAGE(range)`
Calculate the standard deviation with `=STDEV.S(range)`
Create a list of x-values for the distribution
Use `=NORM.DIST(x, mean, standard_dev, FALSE)` to get the normal distribution values
Fill the formula down for all x-values
Create a chart using the x-values and distribution values
Insert a Scatter chart with smooth lines or a Line chart
Format the chart as needed
