Magnets and iron. A compass has a needle that has a magnatized end. If there are outside objects near then it will give a false reading. I have placed a knofe in the console before and had my compass read 20 degrees off.

Iron or steel. Since it is a magnet, a compass will point to iron instead of pointing North.
Accuracy is the distance away in percent of a result (or a measure) from the target. This mathematical definition is from the book "A Mathematical Foundation For Politics And Law"
Accuracy and precision is very important for pilots. Not just for the safety of the aircraft but for the accuracy of your destination. For a two hour flight, a 10 degree off course heading can lead you tens of miles away, or 30 minutes away from your destination.

Accuracy refers to how close you are to the real answer. This is usually used in measurements. For example: The weight is 55.5kg. The accurate measurement will be 60kg which is close to the real answer.

One should consider reading reviews of content management systems. One should be away of the services that are required and compared these to those on offer to ensure the correct system is selected.
Mostly they face away from the beach toward inland. It's believed they were watching over the villages. If you mean compass direction they didn't face any particular compass direction, or they faced various compass directions, whichever you prefer.
