I thought it would be easy to get the RGB values based on the Pantone numbers. It wasn't. When I searched using the numbers from each photo, I found wildly different colors. I wrote to Ms Dass multiple times asking which Pantone color book she was using over a couple of years. I didn't hear back from her. I checked with Pantone. They said the numbers weren't theirs. I wrote to her again, explained my background in clinical studies, and said if I looked at the project as a clinical study I would suspect the data was fraudulent. That got her attention. She sent a terse message stating that she is an artist and I was being passive aggressive. She offered no explanation for why her "Pantone" numbers didn't match with any Pantone numbers.

Yes, the equation gives ...Good question, Saptashwa. Yes, the equation gives us an estimate of the population standard deviation. And yes, that estimate could bigger or smaller than the actual population standard deviation since we are not including all potential data into the computation. But I claim that this estimate of the population standard deviation (when you divide by n) is biased. In the long run, you will get a number slightly smaller than the actual population standard deviation.<br /><br />Why? You need the mean in order to compute the standard deviation. Generally speaking, you use the same data to compute the mean and the standard deviation... but you don't need to. <br /><br />Averaging the data does not give you the true population mean, but rather an estimate of it. That estimate of the mean could be smaller or larger than the population mean. If you pull another sample of data points from the same population, you will likely get a different estimate of the mean.<br /><br />Here is the kicker... of all possible estimates of the mean, the average of your original data set gives the smallest estimate of the standard deviation. The true mean could be bigger or smaller, but we choose the smallest of them to compute the standard deviation? That gives us a bias.John Seymourhttps://www.blogger.com/profile/11350487038873935295noreply@blogger.comtag:blogger.com,1999:blog-1840985738235902482.post-55326327270890363092022-12-08T13:01:47.919-05:002022-12-08T13:01:47.919-05:00But I don't get one thing, the sample standard...But I don't get one thing, the sample standard deviation is an estimator of the population standard deviation, this estimate can be either greater or smaller than the population's one but in writing the 'n-1' in the denominator we are assuming this estimate to be lesser(hence dividing by a smaller number), I don't seem to be convinced of this assumption.
