I think the easiest method is to calculate the skewness and kurtosis of your data. If both are near enough to zero, it's normal. To get the score one method often used is the Jarque-Beta test which gives you the p-value given the calculated skewness and kurtosis. share | cite | improve this answer.
Note that surface texturing or skim coating is NOT included in this estimate. For a basic 500 square feet project in zip code 47474, the benchmark cost to Hang Drywall ranges between $1.43 - $1.76 per square foot* .To estimate costs for your project: 1.or a basic 500 square feet project in zip code 47474, the benchmark cost to Hang Drywall ranges between $1.43 - $1.76 per square foot* . To estimate costs for your project:
Installers will determine the drywall prices by how much labor it will take to hang and finish the total finished area. They will then add in whatever profit they think is reasonable, and divide the total by how many sheets they will actually install and finish. Hence, the cost-per-sheet.You can pay for anywhere from $25 a sheet ($12.50 to hang, and $12.50 to finish) on the cheaper side, on up the scale to as much as $60 a sheet to finish drywall for the pricier projects such as wide arches, vaulted ceilings, etc.nstallers will determine the drywall prices by how much labor it will take to hang and finish the total finished area.
