Similarly, 95% of the people are within 2 standard deviation โ€“ which would be 52-68 Kgs. When you have a dataset that is normally distributed, your bell curve will follow the below rules:

What is the difference between a pivot table and a normal table.
  • Pivot tables are a data analysis/summary tool whereas regular tables are a data organisation tool. They serve quite different goals. If you are not using Pivot tables, you should be.

  • both now support Slicers - if you are not using these, you should be.

  • Advanced filter is an "old" feature which has been largely superceded by power query. If you are not using Power query you should be.

How do you guys format your spreadsheets?
Simple, simple, simple. Maximize content, minimize cognitive load. Monospace 8-pt font (Consolas) except on titles. Black-and-white table styles. Avoid borders. Listobjects whenever possible. Split among worksheets to avoid user side-scrolling. Down-scrolling is okay. Hide unused rows and cols. No gridlines visible. If you need gridlines, IMO you're presenting your data wrong. .5 width cols / 5-height rows as dividers More on reddit.com

r/excel on Reddit: How do I create a distribution of values between 0 and 40 with a specified mean and standard deviation?
October 25, 2024 -

I want to create a column that generates a random range of values between 0 and 40. However, the values must have a mean of 19 a standard deviation of 7.3. The formula

=norm.inv(rand(),19,7.3)

works to a point, but it returns some values in the distribution less than 0 and more than 40.

Is there a way of doing this that can keep all the values between 0 and 40?

Many thanks in advance for anyone who can help.

Yes, that is correct. The Normal distribution has a continuous density function with an infinite range despite a very low probability outside of the second range, not probable but possible, as you can see in the image. Main range (2 sd width): (19-7.3=) 11.7 to 26.3 (=19+7.3) - 68.2% probability to be generated; 2nd range (4 sd width): (19-14.6=) 4.4 to 33.6 (=19+14.6) - 95.4% probability to be generated; 3rd range (6 sd width): (19-21.9=) -2.9 to 40.9 (=19+21.9) - 99.6% probability to be generated; The third range shows that negative values (less than zero) and values higher than 40 are possible with a probability of 2.1% each. A set of 100 random-generated numbers has a high probability of containing 2 negative numbers and 2 numbers higher than 40. It's not an error or bug. The Normal density function extends its domain to infinity and the sum of its extremes never reaches 100% probability. Even if you sum the two extremes (0.1% each) to the third range (99.6%) it reaches 99.8%, or 0.2% of probability spread across the infinite. You may reduce the standard deviation if you wish until negative numbers and >40 numbers stay out of the 3rd range. You need to move the mean a bit higher to 20 because the negatives reach -2.9 lower while the >40 reach only 0.9 higher. If you want to force the Excel Normal distribution artificially, you may use: = MAX(0, MIN(40, NORM.INV( RAND(), 19, 7.3 ) ) ) but statistically speaking you're "distorting the numbers". Edit: There are two other methods, more scientifically recommended. One of them is to do an inverse distribution table with the values of ranges you want, but it's a bit time-consuming to explain this here. The second method is quite easy and you don't need to use the NORM.INV function. Just sum 6 RAND() functions (do not multiply) and divide by 6. This method will generate numbers 0 to 1 normally distributed, like this: = ( RAND() + RAND() + RAND() + RAND() + RAND() + RAND() )/6 Then you can adapt the resulting range [0 to 1] to your desired range [0 to 40], with a mean of 19 and a standard deviation of 7.3, however, this adaptation is not a guarantee that <0 and >40 numbers will not show up. I hope this helps.
