Normal Distribution Graph in Excel
Excel has a built-in function for finding mean and standard deviation for a set of values, and a normal distribution graph is a graphical representation of these normal distribution values in Excel. A formula has been discovered in Excel to find a normal distribution, which is categorized under statistical functions.
How to Calculate Normal Distribution in Excel?
The normal distribution is a statistical function that helps to obtain a distribution of values based on a mean value, which can be calculated using the built-in formula. We will also need the mean and standard deviation to find the normal distribution.
How to Make Normal Distribution Graph in Excel?
Making a normal distribution graph in Excel is simple and straightforward. We can plot the normal distribution for each person’s marks by sorting the mark column from lowest to highest, resulting in a bell-shaped graph with the highest point at the top.
Things to Remember
When the mean or standard deviation is not numeric, the error value #VALUE is returned. A normal distribution graph in Excel is a graphical representation of normal distribution values that shows the scattering of values from the mean by sorting the values with the NORM.DIST function.

How do you create a distribution curve in Excel?
Using Excel to Make a Bell Curve
- In cell A1, enter 35.
- In the cell below it, enter 36 and create a series from 35 to 95 (where 95 is Mean 3* Standard Deviation).
- In the cell adjacent to 35, enter the formula: =NORM.DIST(A1,65,10,FALSE).
Can you create a bell curve in Excel?
Select the data points and normal distribution values, then use the Scattered with Smooth Lines version of the X-Y Scatter chart to create a bell curve in Excel.
How do you sketch a normal distribution?
Draw a horizontal line (axis) first, then a normal (bell-shaped) curve centered on it. Finally, draw a vertical line from the horizontal axis through the center of the curve, cutting it in half.
How do you standardize a normal distribution?
By converting the values of any normal distribution into z-scores, any normal distribution can be standardized.
- Your x-value is greater than the mean if your z-score is positive. If your z-score is negative, your x-value is less than the mean. If your z-score is zero, your x-value is equal to the mean.
How do you interpret a normal distribution curve?
The area under the normal distribution curve represents probability, and the total area under the curve equals one. In a normal distribution, most continuous data values cluster around the mean, and the farther a value is from the mean, the less likely it is to occur.
How do you calculate bell curve?
Use the bell curve formula to calculate the y axis value for each x axis value. The bell curve formula is y = (e(?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?-x?
What is a bell curve grading system?
Grading on a curve, also known as bell curving, is a grading method in which students’ grades are distributed over a normal distribution, resulting in a majority of students receiving a grade that is close to the average.
What does a bell curve indicate?
The top of the curve shows the mean, mode, and median of the data collected; the bottom of the curve shows the mean, mode, and median of the data collected. Bell curves (normal distributions) are commonly used in statistics, including in analyzing economic and financial data.
How do you calculate the Z score?
The z-score is calculated using the formula z = (x-)/, where x is the raw score, y is the population mean, and z is the population standard deviation.
How do you draw a normal distribution curve in Word?
Make a curve.
- Click Shapes on the Insert tab, then Lines, then Curve.
- Click where you want the curve to start, drag to draw, and then click wherever you want to add a curve.
- To end a shape, do one of the following: double-click at any time to leave it open, or click near its starting point to close it.
How do you know if data is normally distributed?
You can also visually check for normality by plotting a frequency distribution of the data (also known as a histogram) and visually comparing it to a normal distribution (overlaid in red). In a frequency distribution, each data point is placed into a discrete bin, such as (-10,-5], (-5, 0], (0, 5], etc.
