<div>
So you want to generate <i>n</i> numbers within a range and the average of those should match a given number?<br />
<br />
Are there any constraints other than the max/min?
</div>


<div>
Exactly! <br />
<br />
That's what it should do, probably later i would try something to smooth the numbers so it wouldn't be far from each other because it will be a graph, but for now i'm just focusing in generate &quot;n&quot; numbers and the average of the range should match the given number. (Which is important).

Thinking out loud algorithm...<br />
<br />
1) Fill a List with X numbers at exactly your desired Average.<br />
2) For each Value, pick a direction (up/down) to move, and pick a distance that keeps it within the min/max values.<br />
3) Pick a different random value and move it the opposite direction by that distance, as long as it stays within the min/max values.<br />
4) Repeat numbers 2 and 3 for all values several times.

Well i'm writing it in vb.net, what i'm trying to do is exactly what Mike mentioned, but still, really thank you for the help!!<br />
<br />
<b>@Mike</b><br />
This is a little visual example of what i'm trying to do.<br />

I'm at work right now so I can't code. If no one has satisfactorily answered by the time I settle down this evening, ill see if I can whip something up.

Whenever the Generate button is pressed do you want to, well, generate a new set of <i>n</i> numbers that fit the criteria?
</div>


<div>
Yes!, &nbsp;whenever i press the generate button, it does use the settings on the left.

Congratulations!!!<br />
<br />
That's exactly what i need, i have been testing it, i'm using this to make a Personal protective equipment (PPE) attenuation Simulator to get a random average attenuation so i can export the generated data and import into a software. Is there a way to add another condition so it would insert random peak values (a little high values) ? If not that's pretty okay!<br />
<br />
<u>Here is the result of the Function into my code.</u><br />

&quot;Is there a way to add another condition so it would insert random peak values (a little high values) ?&quot;<br />
<br />
I'm sure it's possible...should there be a corresponding low value?...or should the difference be spread out among several other values? &nbsp;How many peaks should there be? &nbsp;Do you want one, two, or three?...or maybe calculate a low percentage of peak values. &nbsp;Does a peak value come within X% of the max?...or does it exceed the max? &nbsp;So many questions and ways to do this...
</div>


<div>
<b>Ok, let's see:<br />
<br />
1) Should there be a corresponding low value? or should the difference be spread out among several other values?</b><br />
The difference should be spread out among several other values.<br />
<br />
<b>2) How many peaks should there be? &nbsp;Do you want one, two, or three?...or maybe calculate a low percentage of peak values. </b><br />
I guess if it calculates a low percentage of peak values could be awesome!<br />
<br />
<b>3) Does a peak value come within X% of the max?...or does it exceed the max? </b><br />
No, it shouldn't exceed the maximum value given. but there could be a little percentage it could reach the max or somewhat near.<br />
<br />
I guess with these conditions it should generate a consistent &quot;Average Noise&quot; data simulation.<br />
<br />
I'm really happy with the results so far, Thank you!

Even though the topic was not finished, Thank you a lot @Mike for helping me with the app and @it_saige for giving it a start.

Hello Experts!<br />
<br />
I'm trying to do a little function for my app, but i really don't know to do it.<br />
<br />
<u><b>Example:</b></u><br />
<br />
I want to do a function where i give it a range (Min / Max), Average and How many records like:<br />
<br />
<b>Min:</b> 67.9<br />
<b>Max:</b> 101.9<br />
<b>Records:</b> 5<br />
<b>Average:</b> 74.4<br />
<br />
So it should generate into my DataGridView1 (Or DataTable) 5 records of numbers with a final average of 74.4.<br />
<br />
<b>The Result:</b><br />

<pre><code class="code-1 nolinks" id="code-10-29071125-1"><span>73.2</span>
<span>75.6</span>
<span>71.1</span>
<span>77.4</span>
<span>74.7</span>
<span></span>
<span>Average: 74.4</span>
</code></pre>
<br />
How can i do this?

[VB.NET] Generate Random Numbers by Given Range and Given Average

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,
