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.
The Average Cost of Hardwood Floors. It's no secret that hardwood floors are in demand, but the high cost of this material may stop budget-conscious homeowners in their tracks. MarketWatch estimates the cost of hardwood at $3.50 to $12.95 per square foot as of June 2014. This figure doesn't include installation, which can run an additional $2.75 to $6.75 per square foot unless you decide to install the flooring yourself.
