What is metric and non metric data?

Answer 1

Metric variables have numbers associated with them. For example: Team Members in a Call Center can be evaluated by how many calls they take per day. How many minutes they spend on average on those calls. The difficulty level of the calls they took, etc.

Non Metric variables are intrinsic. The weather can affect an outdoor wedding, that is a non metric variable. In the record business, the non metric variable of illegal downloads affects the bottom line for the record producer. In this case the number of downloads is an unknown.

Answer 2

There are several differences and all of them are advantages in the metric system.

1. The metric system is internationally agreed as standard. Not like a gallon which can mean one amount in the US and different amount in the UK.

2. Orders of magnitude for measuring the same attribute in the metric system are related by simple multiples or fractions of powers of ten conversions and only a handful of prefices are required (although there are a lot more). By way of contrast, the Imperial system uses:

• 2 pints in a quart

• 3 feet in a yard

• 4 quarts in a gallon

• 6 feet in a fathom

• 8 furlongs in a mile

• 9 square feet in a square yard

• 12 inches in a foot

• 14 pounds in a stone

• 16 ounces in a pound

and so on, and on and on. The decimal structure also makes it simple to use scientific notation for very small and very large quantities.

3. There are many simple relations between measures for one characteristic to another. For example, the force required to accelerate a mass of 1 kilogram by 1 metre/second^2 is 1 Newton. The pressure exerted by 1 Newton over an area of 1 Square metre is 1 Pascal.

Answer 3

maybe its all about measurements
