2. I have data sets (measurements) and I need to know if values are normally distributed. I would like to get this information programmatically in my application and not via plotting and checking it visually myself.
1 Installing a standard solid-strip hardwood floor averages about $8 a square foot for materials, insulation and site finishing, and up to $12 a square foot for wide pine planks, or $1,150-$1,750 for a 12x12-foot room.
Installing hardwood flooring costs between $250 and $7,000, but the total price will vary depending on many factors. Some of those factors include what kind of flooring you decide to install, its quality or grade and how complex the installation job will be for a professional.
