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.
Average cost to install hardwood flooring is about $4,000 - $5,000 (200 sq.ft. of oak wood flooring and a new plywood subfloor). Find here detailed information about hardwood floor installation costs.
